Description
本發明關於電池組用框體、蓄電池、電池組、蓄電池系統、電池組用框體的散熱性提升方法及電池組用框體的耐變形性提升方法。The invention relates to a method for improving heat dissipation of a battery pack frame, a battery, a battery pack, a battery system, a battery pack frame, and a method for improving the deformation resistance of a battery pack frame.
如第7圖所示，在閥控式鉛蓄電池1(以下，有時也僅稱為「蓄電池」)中，正極板2和負極板3隔著墊子狀隔片(separator)4(以下有時也僅稱為「隔片」)而交互地積層，並藉由熔接來連接同極性的電極板彼此的耳部來構成電極板群。在閥控式鉛蓄電池1中，將此電極板群收納在成為電池槽之框體10中，並利用熔接或黏結劑將具有正極端子6a、負極端子6b及排氣孔6c之蓋子6黏結在成為此電池槽之框體10上。閥控式鉛蓄電池1，是自排氣孔6c注入電解液來實行電池化成(battery jar forming)，並將控制閥(未圖示)覆蓋在排氣孔6c上來製造。As shown in FIG. 7, in a valve-regulated lead-acid battery 1 (hereinafter, sometimes referred to simply as a “battery”), the positive electrode plate 2 and the negative electrode plate 3 are separated by a spacer-like separator 4 (sometimes hereinafter (Also referred to as a "separator"), which are laminated alternately, and the electrode portions of electrode plates of the same polarity are connected by welding to form an electrode plate group. In the valve-regulated lead-acid battery 1, this electrode plate group is housed in a frame 10 serving as a battery tank, and a lid 6 having a positive terminal 6a, a negative terminal 6b, and an exhaust hole 6c is bonded to each other by welding or an adhesive. It becomes the frame body 10 of this battery slot. The valve-regulated lead-acid battery 1 is manufactured by injecting electrolyte from the exhaust hole 6c to perform battery jar forming, and covering the exhaust hole 6c with a control valve (not shown).
近年來，對於風力發電或太陽能發電等的利用自然能源來進行之發電設備，與其一起設置的循環用閥控式鉛蓄電池的需求增加。在此用途上被使用的蓄電池系統，具備蓄電池收納箱來收納複數個閥控式鉛蓄電池，並藉由將各蓄電池串聯或並聯而成的電池組來構成(例如，參照專利文獻1)。In recent years, there has been an increasing demand for cycle-regulated valve-regulated lead-acid batteries for power generation facilities using natural energy, such as wind power or solar power. A storage battery system used for this purpose includes a storage battery box to store a plurality of valve-regulated lead storage batteries, and is configured by a battery pack in which the storage batteries are connected in series or in parallel (for example, refer to Patent Document 1).
[先前技術文獻] (專利文獻) 專利文獻1：日本特開2014-235803號公報[Prior Art Document] (Patent Document) Patent Document 1: Japanese Patent Application Laid-Open No. 2014-235803
[發明所欲解決的問題] 對於使用這種電池組之先前的蓄電池系統，若反覆地進行充放電，則由於各個蓄電池的發熱會引起溫度上升，可能會造成循環壽命特性惡化。因此，電池組的散熱性是重要的。在專利文獻1中揭露一種蓄電池系統，其在各個蓄電池之間配置隔板(partition plate)，前述隔板具備可進行空氣對流之空洞部，並在與框體的電極板的積層方向平行之方向的面上不形成肋部(rib)(凸部)，藉此使前述框體與前述隔板的側板能夠以面接觸的方式來配置，該框體成為蓄電池的電池槽。在專利文獻1中，使前述框體與前述隔板的側板能夠以面接觸的方式來配置，並使前述隔板具備可以進行空氣對流之空洞部，藉此提升電池組的散熱性。[Problems to be Solved by the Invention] If a conventional battery system using such a battery pack is repeatedly charged and discharged, the temperature rise due to the heat generated by each battery may deteriorate cycle life characteristics. Therefore, the heat dissipation of the battery pack is important. Patent Document 1 discloses a storage battery system in which a partition plate is provided between the storage batteries, the partition plate having a cavity portion capable of air convection, and a direction parallel to a lamination direction of an electrode plate of a frame body The ribs (convex portions) are not formed on the surface, so that the frame body and the side plate of the separator can be placed in surface contact with each other, and the frame body becomes a battery slot for a battery. In Patent Document 1, the frame and the side plate of the separator can be disposed in surface contact with each other, and the separator is provided with a cavity portion capable of air convection, thereby improving the heat dissipation of the battery pack.
又，在大型的閥控式鉛蓄電池中，一般來說，為了提高成為電池槽之框體的強度而會在框體的全部側面上設置肋部(凸部等)。上述肋部，具有抑制由於群壓所造成的框體膨脹之效果。在專利文獻1揭露的蓄電池系統中的蓄電池，在與框體的電極板的積層方向正交之面上形成有肋部，以抑制由於群壓所造成的框體膨脹。另外，群壓，是指將正極板和負極板隔著隔片而交互地積層(將這些稱為電極板群)，當自積層方向的兩端推壓時的推斥力(repulsive force)。當將電極板群(正極板、負極板、隔片)插入成為電池槽之框體時，為了抑制循環壽命惡化的一個主要原因，也就是正極活性物質的軟化現象，而必須在電極板的積層方向上壓迫電極板群，而造成隔片成為被壓潰的狀態。Moreover, in a large-scale valve-regulated lead-acid battery, generally, in order to increase the strength of the frame body to be a battery tank, ribs (projections, etc.) are provided on all sides of the frame body. The ribs have the effect of suppressing the expansion of the frame due to the group pressure. In the storage battery in the storage battery system disclosed in Patent Document 1, ribs are formed on a surface orthogonal to the lamination direction of the electrode plates of the frame to suppress the expansion of the frame due to the group pressure. In addition, the group pressure refers to a repulsive force when a positive electrode plate and a negative electrode plate are alternately laminated with a separator interposed therebetween (these are referred to as an electrode plate group) and are pushed from both ends in the direction of the lamination. When inserting the electrode plate group (positive electrode plate, negative electrode plate, and separator) into the frame of the battery tank, in order to suppress the deterioration of cycle life, that is, the softening of the positive electrode active material, it is necessary to laminate the electrode plate. The electrode plate group is pressed in the direction, and the separator is crushed.
但是，專利文獻1，在各個蓄電池的框體之間設置隔板來作為與框體的側板不同的構件，此隔板具備能夠進行空氣對流之空洞部，所以必須佔用在蓄電池彼此之間的空間，而可能造成電池組的體積變大。進一步，也造成電池組的構成零件數變多而不佳。However, in Patent Document 1, a partition is provided between the casings of each battery as a member different from the side plate of the casing. This partition has a hollow portion capable of air convection, so it must occupy the space between the batteries. , Which may cause the volume of the battery pack to become larger. Furthermore, the number of component parts of the battery pack is also increased and unsatisfactory.
又，鉛蓄電池，當過度充電時可能會產生氣體並使得電池槽內的壓力上升。又，在鉛蓄電池中，當放電時，在正極和負極的任一個電極中，電極活性物質都會產生放電生成物(硫酸鉛(PbSO4 ))。放電生成物，相較於正極的正極活性物質也就是二氧化鉛(PbO2 )和負極的負極活性物質也就是金屬鉛(Pb)，具有更大的體積。因此，鉛蓄電池，相較於其他蓄電池(例如鋰離子電池)，在將正極和負極積層而成之電極板群的積層方向，對相對向的側壁施加的壓力大。In addition, lead storage batteries may generate gas when overcharged and cause the pressure in the battery tank to rise. Further, in a lead storage battery, when discharged, either of the positive electrode and the negative electrode, an electrode active material generates a discharge product (lead sulfate (PbSO 4 )). The discharge product has a larger volume than the positive electrode active material of the positive electrode, which is lead dioxide (PbO 2 ), and the negative electrode active material of the negative electrode, which is metal lead (Pb). Therefore, compared to other storage batteries (for example, lithium ion batteries), lead batteries have a greater pressure on the opposite side wall in the direction of the electrode plate group formed by laminating the positive electrode and the negative electrode.

The description will be made with reference to FIG. 5, but the battery pack housing, battery, battery pack, and battery system of the present invention are not limited to the following embodiments.
如第2圖(a)～第2圖(c)、第3圖、第4圖及第5圖所示，本實施形態的電池組用框體10，當構成具備有複數個蓄電池1之電池組(未圖示)時，用作構成前述電池組的各個蓄電池1中的至少一個的框體10，其中，將複數個電極板2、3以積層狀態來加以收容，在前述電極板2、3的積層方向22上相對向之對向外壁13A、13B，具備了在與鄰接的其他蓄電池1的框體的外壁20(未圖示)之間形成空洞(未圖示)之非接觸凹部。As shown in FIGS. 2 (a) to 2 (c), 3, 4 and 5, the battery pack frame 10 of this embodiment is configured as a battery including a plurality of storage batteries 1. In the case of an assembly (not shown), the housing 10 is used as at least one of the storage batteries 1 constituting the battery pack. A plurality of electrode plates 2 and 3 are housed in a laminated state. The stacking direction 22 of 3 is opposite to the outer walls 13A and 13B, and is provided with a non-contact recessed portion that forms a cavity (not shown) with the outer wall 20 (not shown) of the frame of another adjacent storage battery 1.
在本實施形態中，蓄電池1是指可以充電和放電之電池，也就是鉛電池。又，在本實施形態中，當僅提到蓄電池1時，就是單電池(一個蓄電池)。相對於此，電池組，是指連接有複數個蓄電池1而構成之蓄電池的集合體。In this embodiment, the storage battery 1 refers to a battery that can be charged and discharged, that is, a lead battery. In this embodiment, when only the storage battery 1 is mentioned, it is a single battery (a single storage battery). In contrast, the battery pack refers to an assembly of storage batteries configured by connecting a plurality of storage batteries 1.
蓄電池1的框體10，是收容電極板2、3並儲存電解液之電池槽。電池組用框體10，當構成具備有複數個蓄電池1之電池組時，用作構成電池組的各個蓄電池1中的至少一個的電池組用框體。在本實施形態中，有時將電池組用框體10簡稱為框體10。當構成具備有複數個蓄電池1之電池組時，在統整地構成複數個蓄電池1時，一般來說是使用蓄電池收容箱。蓄電池收容箱是收容複數個蓄電池1之容器，該複數個蓄電池1包含具備有電池組用框體10之蓄電池1。The casing 10 of the storage battery 1 is a battery tank that houses the electrode plates 2 and 3 and stores an electrolytic solution. When the battery pack housing 10 constitutes a battery pack including a plurality of storage batteries 1, the battery pack housing 10 is used as a battery pack housing for at least one of the respective storage batteries 1 constituting the battery pack. In this embodiment, the battery case 10 may be simply referred to as the case 10. When a battery pack including a plurality of storage batteries 1 is constructed, and when a plurality of storage batteries 1 are constructed in an integrated manner, a storage battery case is generally used. The battery storage box is a container for storing a plurality of batteries 1, and the plurality of batteries 1 include a battery 1 including a battery pack frame 10.
電極板2、3，在蓄電池1中，是作為正極而發揮機能之正極板2或作為負極而發揮機能之負極板3。作為電極板2、3，如後述，舉例有糊式電極板(paste type electrode plate)、包覆式電極板(cladding type electrode plate)等。在本實施形態中，電極板也就是正極板2和負極板3，隔著用來防止兩電極板2、3之間的短路之隔片4，並在交互地積層的狀態下，被收容在電池組用框體10中。The electrode plates 2 and 3 are the positive electrode plate 2 functioning as a positive electrode or the negative electrode plate 3 functioning as a negative electrode in the battery 1. Examples of the electrode plates 2 and 3 include a paste type electrode plate, a cladding type electrode plate, and the like, as described later. In this embodiment, the electrode plates, that is, the positive electrode plate 2 and the negative electrode plate 3 are housed in a state of being laminated alternately via a spacer 4 for preventing a short circuit between the two electrode plates 2 and 3. The battery pack housing 10.
電極板2、3的積層方向22，是正極板2和負極板3隔著隔片4來積層的方向。積層方向22，是與電極板2、3的電極面正交之方向。對向外壁13A、13B，是電池組用框體10的外壁20當中，在電極板2、3的積層方向22上相對向之外壁。對向外壁13A、13B，是以覆蓋電極板2、3的電極面的方式配置之框體10的外壁。The lamination direction 22 of the electrode plates 2 and 3 is a direction in which the positive electrode plate 2 and the negative electrode plate 3 are laminated via the separator 4. The lamination direction 22 is a direction orthogonal to the electrode surfaces of the electrode plates 2 and 3. The outer walls 13A and 13B are, among the outer walls 20 of the battery pack frame 10, facing the outer walls in the laminated direction 22 of the electrode plates 2 and 3. The outer walls 13A and 13B are outer walls of the frame body 10 arranged so as to cover the electrode surfaces of the electrode plates 2 and 3.
在框體10的外壁20上具備的非接觸凹部21，當構成具備有複數個蓄電池1之電池組時，在與鄰接的其他蓄電池1的框體10的外壁20之間形成空洞。將具有非接觸凹部21之外壁20，稱為凹狀外壁(未圖示)。當構成電池組時，將複數個蓄電池1收納在蓄電池收納箱(未圖示)中並將這些蓄電池1連接時，此非接觸凹部21不僅在鄰接的蓄電池之間，也在與蓄電池收納箱等的其他構件之間形成空洞。此處，空洞(未圖示)，是指與包含其他蓄電池1和蓄電池收納箱之電池組的任一個構件都沒有接觸之空間。When the non-contact recessed portion 21 provided on the outer wall 20 of the housing 10 constitutes a battery pack including a plurality of storage batteries 1, a cavity is formed between the non-contact recessed portion 21 and the outer wall 20 of the housing 10 of another adjacent storage battery 1. The outer wall 20 having the non-contact recessed portion 21 is referred to as a concave outer wall (not shown). When constituting a battery pack, when a plurality of storage batteries 1 are stored in a storage battery case (not shown) and the storage batteries 1 are connected, the non-contact recess 21 is not only between adjacent storage batteries but also with the storage battery case, etc. Voids are formed between the other components of. Here, the cavity (not shown) refers to a space that is not in contact with any member of the battery pack including the other storage battery 1 and the storage battery case.
亦即，在本實施形態的框體10的對向外壁13A、13B上設置的非接觸凹部21，是藉由向框體10的內側(內部)凹陷的凹形狀而形成的部位。非接觸凹部21，相較於連接對向外壁13A的外周端部13AX與外周端部13AY之直線、及連接對向外壁13B的外周端部13BX與外周端部13BY之直線，不具有在積層方向22上更向外側突出的部位。在本實施形態中，非接觸凹部21不具有向外側突出的凸部。具體來說，非接觸凹部21，在外周端部13AX與外周端部13AY之間、及在外周端部13BX與外周端部13BY之間，不具有自對向外壁13A、13B向外側突出的凸部。亦即，非接觸凹部21，是由直線或曲線的連續面所形成。因此，非接觸凹部21，不相當於如專利文獻1所揭露的當在框體10的外壁20上設置凸狀的肋部時的於肋部之間所形成的凹陷。That is, the non-contact recessed portions 21 provided on the outer walls 13A and 13B of the frame body 10 according to the present embodiment are formed in a concave shape recessed toward the inside (inside) of the frame body 10. The non-contact recessed portion 21 does not have a line in the stacking direction compared to a straight line connecting the outer peripheral end portion 13AX and the outer peripheral end portion 13AY to the outer wall 13A and a straight line connecting the outer peripheral end portion 13BX and the outer peripheral end portion 13BY to the outer wall 13B. The part 22 protruding more outward. In the present embodiment, the non-contact recessed portion 21 does not have a convex portion protruding outward. Specifically, the non-contact recessed portion 21 does not have a protrusion protruding outward from the outer wall 13A, 13B between the outer peripheral end portion 13AX and the outer peripheral end portion 13AY, and between the outer peripheral end portion 13BX and the outer peripheral end portion 13BY. unit. That is, the non-contact recessed part 21 is formed by a continuous surface of a straight line or a curved line. Therefore, the non-contact recessed portion 21 does not correspond to the recess formed between the ribs when the convex ribs are provided on the outer wall 20 of the frame 10 as disclosed in Patent Document 1.
在本實施形態的框體10的對向外壁13A、13B上設置的非接觸凹部21，是在與鄰接的其他蓄電池1的框體的外壁20之間形成空洞之凹部。藉由非接觸凹部21形成的空洞(未圖示)，是與包含其他蓄電池1之電池組的任一個構件都沒有接觸的空間。因此，非接觸凹部21，不相當於為了使蓄電池1並排並使框體10的外壁20彼此嵌合而在框體10的外壁20上形成的凹陷。The non-contact recessed portions 21 provided on the outer walls 13A and 13B of the frame body 10 of the present embodiment are recessed portions that form a cavity between the outer wall 20 of the frame body of another adjacent storage battery 1. A cavity (not shown) formed by the non-contact recessed portion 21 is a space that does not come into contact with any member of the battery pack including the other storage batteries 1. Therefore, the non-contact recessed portion 21 does not correspond to a depression formed on the outer wall 20 of the housing 10 in order to fit the storage batteries 1 side by side and fit the outer walls 20 of the housing 10 to each other.
作為本實施形態的框體10上設置的非接觸凹部21的例子，其框體10的橫剖面形狀(與底壁11平行之方向的剖面)，舉例有如第2圖(a)和第3圖所示的梯形狀、如第2圖(b)和第4圖所示的三角形狀、如第2圖(c)和第4圖所示的U字形狀。本發明的電池組用框體10，不受限於上述的第2圖(a)～第2圖(c)、第3圖、第4圖或第5圖所示的構造，只要於在電極板2、3的積層方向上相對向之對向外壁13A、13B上具有非接觸凹部21，此非接觸凹部與其他蓄電池1的框體10所具有的凸部等沒有嵌合即可，非接觸凹部21的形狀、底壁11和開口部12的形狀、側壁14A、14B的形狀、數量等沒有特別限定。As an example of the non-contact recessed portion 21 provided in the frame body 10 of this embodiment, the cross-sectional shape of the frame body 10 (a cross-section in a direction parallel to the bottom wall 11) is exemplified in FIG. 2 (a) and FIG. 3 The ladder shape shown is a triangular shape as shown in Figs. 2 (b) and 4 and a U-shape as shown in Figs. 2 (c) and 4. The housing 10 for a battery pack of the present invention is not limited to the structure shown in Figs. 2 (a) to 2 (c), 3, 4, or 5 as long as it is on the electrode Plates 2 and 3 have non-contact recessed portions 21 on the opposite walls 13A and 13B opposite to each other. This non-contact recessed portion does not fit into the convex portion of the frame 10 of the other battery 1. The shape of the recessed portion 21, the shape of the bottom wall 11 and the opening portion 12, the shape and number of the side walls 14A and 14B are not particularly limited.
框體10的角部(稜角部，corner)，自應力難以集中在角部，當輸送時等的情況不易由於衝突而造成框體的破損的觀點來看，較佳是帶有圓弧。The corners (corners, corners) of the frame 10 are difficult to concentrate at the corners, and it is preferable that the frames have arcs from the viewpoint that it is not easy to damage the frame due to collisions during transportation.
作為在框體10的電極板2、3的積層方向上相對向之對向外壁13A、13B的非接觸凹部21的形狀，特佳是在電極板2、3的積層方向上相對向之對向外壁被彎曲並形成U字狀之凹形狀。框體10的對向外壁13A、13B彎曲成U字形狀，藉此更提升抵抗群壓之強度。即便當要使框體10得到與先前相同的強度時，也能夠減少框體10的材料的使用量而具有可以輕量化的優勢。As the shape of the non-contact recessed portions 21 facing the outer walls 13A and 13B in the stacking direction of the electrode plates 2 and 3 of the housing 10, it is particularly preferable that they are facing each other in the stacking direction of the electrode plates 2 and 3 The outer wall is bent and formed into a U-shaped concave shape. The opposite sides of the frame body 10 are bent into a U-shape to the outer walls 13A and 13B, thereby increasing the strength against the group pressure. Even when the frame 10 is required to have the same strength as before, it is possible to reduce the amount of material used in the frame 10 and to reduce weight.
框體10的具有非接觸凹部21之凹狀外壁，也可以僅是對向外壁13A、13B的其中一方的面。但是，較佳是對向外壁13A、13B在電極板2、3的積層方向上相對向，且具有互相對向的面，其對向外壁13A、13B的兩面都是各自具有非接觸凹部21之凹狀外壁。The concave outer wall of the frame body 10 having the non-contact recessed portion 21 may be a surface facing only one of the outer walls 13A and 13B. However, it is preferable that the outer walls 13A and 13B are opposite to each other in the lamination direction of the electrode plates 2 and 3 and have mutually opposed faces, and both surfaces thereof facing the outer walls 13A and 13B each have a non-contact recess 21. Concave outer wall.
框體10的材料並沒有特別限定，例如，較佳是容易成形的合成樹脂，自容易得到充分強度的觀點來看，特佳是ABS樹脂(丙烯腈-丁二烯-苯乙烯共聚合成樹脂)。The material of the frame 10 is not particularly limited. For example, a synthetic resin that is easy to form is preferred. From the viewpoint of obtaining sufficient strength easily, ABS resin (acrylonitrile-butadiene-styrene copolymerization resin) is particularly preferred. .
框體10的製作方法並沒有特別限定，自生產性優異的觀點來看，例如，也可以是射出成型。The method of manufacturing the frame body 10 is not particularly limited, and from the viewpoint of excellent productivity, for example, it may be injection molding.
(作用和效果) 本實施形態的電池組用框體10，其於在電極板2、3的積層方向上相對向之對向外壁13A、13B上具有非接觸凹部21。非接觸凹部21，在與鄰接的其他蓄電池1的框體10的外壁20之間，形成有與電池組的任一個構件都沒有接觸的空間之空洞。例如，當將複數個使用了本實施形態的框體10之蓄電池1，收納在電池組製作用的蓄電池用收納箱中時，使框體10的凹狀外壁相對向並重疊，而在鄰接的蓄電池之間形成空洞。又，例如，當將複數個使用了本實施形態的框體10之蓄電池1，收納在電池組製作用的蓄電池用收納箱中時，使框體10的凹狀外壁相對向於蓄電池用收納箱內面，而在已收納的各蓄電池1與蓄電池收納箱內面之間形成空洞。因此，本實施形態的框體10的非接觸凹部21，與以框體10的外壁彼此嵌合的方式設置的凹凸形狀不同，在凹陷內具有與電池組的任一個構件都沒有接觸的部位，所以能夠確保空洞，該空洞成為空氣的通道而用以散熱的空間。藉此，自框體10將熱量傳遞至此空洞的空間中包含的空氣，藉由此空氣在空洞中移動而可以進行散熱。(Actions and Effects) The battery pack frame 10 of this embodiment has a non-contact recessed portion 21 on the outer walls 13A, 13B which are opposed to each other in the lamination direction of the electrode plates 2 and 3. The non-contact recessed portion 21 forms a cavity in a space between the non-contact recessed portion 21 and the outer wall 20 of the casing 10 of the other adjacent storage battery 1 without contact with any member of the battery pack. For example, when a plurality of storage batteries 1 using the housing 10 of this embodiment are stored in a storage box for a storage battery for producing a battery pack, the concave outer walls of the housing 10 are opposed and overlapped, and the adjacent Cavities formed between the batteries. In addition, for example, when a plurality of storage batteries 1 using the housing 10 of this embodiment are stored in a storage box for a storage battery for battery pack production, the concave outer wall of the housing 10 is opposed to the storage box for the storage battery. An inner surface, and a cavity is formed between each stored battery 1 and the inner surface of the battery storage box. Therefore, the non-contact recessed portion 21 of the frame body 10 of this embodiment is different from the concave-convex shape provided by fitting the outer walls of the frame body 10 to each other. Therefore, a cavity can be secured, and the cavity becomes a space for air to be used for heat dissipation. Thereby, heat is transferred from the frame body 10 to the air contained in the hollow space, and thus the air can be dissipated by moving the air through the hollow space.
本實施形態的非接觸凹部21，與具有突出至外側之凸部的先前技術(專利文獻1)的肋部不同，是藉由向框體10的內側凹陷的凹形狀而形成的部位。因此，在框體10中，能夠抑制單個蓄電池1的體積的增加。The non-contact recessed portion 21 of this embodiment is a portion formed by a concave shape recessed toward the inside of the frame body 10 unlike the rib of the prior art (Patent Document 1) having a protruding portion protruding to the outside. Therefore, in the casing 10, it is possible to suppress an increase in the volume of the single storage battery 1.
非接觸凹部21，能夠作為框體10自身的形狀，並與框體10一體地成形。因此，即便當組合複數個蓄電池1並構成電池組時，也能夠確保蓄電池1彼此之間的用以散熱的空間，所以電池組彼此之間不需要設置先前的隔板。這樣一來，本實施形態的框體10，不需要用以提升散熱性之別的零件而能夠減少構成零件數量。The non-contact recessed portion 21 can be formed into the shape of the frame body 10 itself and be formed integrally with the frame body 10. Therefore, even when a plurality of storage batteries 1 are combined to form a battery pack, a space for dissipating heat between the storage batteries 1 can be ensured, so there is no need to provide a previous partition between the battery packs. In this way, the frame body 10 of the present embodiment can reduce the number of constituent parts without requiring other parts for improving heat dissipation.
進一步，本實施形態的框體10，因為在對向外壁13A、13B上設置有非接觸凹部21，所以相較於先前的僅具有平板狀的外壁20之框體10，具有更優異的強度。非接觸凹部21，被設置於在電極板2、3的積層方向上相對向之對向外壁13A、13B上，所以具有抵抗在電極板2、3的積層方向上產生的群壓之耐變形性。Furthermore, since the frame body 10 of this embodiment is provided with the non-contact recessed portion 21 on the outer wall 13A, 13B, the frame body 10 has more excellent strength than the frame body 10 having the flat outer wall 20 only. The non-contact recessed portion 21 is provided on the outer wall 13A, 13B opposite to each other in the laminated direction of the electrode plates 2 and 3, so it has resistance to deformation against the group pressure generated in the laminated direction of the electrode plates 2 and 3. .
如以上所述，本實施形態的電池組用框體10，具備了於在電極板2、3的積層方向上相對向之對向外壁13A、13B上設置的上述非接觸凹部21。藉此，能夠提供一種電池組用框體10，其抑制電池組的體積和構成零件數的增加，並且兼顧抵抗群壓之蓄電池1的框體10的耐變形性和蓄電池1的散熱性。As described above, the battery pack frame 10 of the present embodiment includes the non-contact recessed portion 21 provided on the outer walls 13A and 13B opposite to each other in the laminated direction of the electrode plates 2 and 3. Thereby, it is possible to provide a battery pack frame 10 that suppresses the increase in the volume of the battery pack and the number of constituent parts, and also takes into consideration the deformation resistance of the frame 10 of the battery 1 that resists group pressure and the heat dissipation of the battery 1.
在電極板2、3的積層方向上相對向之對向外壁13A、13B的非接觸凹部21，相較於前述對向外壁13A、13B的外周端部，是更向框體10的內側(內部)凹陷的凹形狀。例如，如第2圖(a)、第3圖(b)及第4圖(b)所示，非接觸凹部21，相較於對向外壁13A的外周端部(寬度方向兩端部)13AX、13AY以及對向外壁13B的外周端部(寬度方向兩端部)13BX、13BY，是更向框體10的內側(內部)凹陷的凹形狀。也就是說，對向外壁13A、13B，不具有向外側突出的凸部，所以能夠抑制單個蓄電池1的體積的增加。因此，在本實施形態的框體10上設置的非接觸凹部21，不相當於如專利文獻1所揭露的當在框體10的外壁20上設置凸狀的肋部時的於肋部之間形成的凹陷。The non-contact recessed portions 21 facing the outer walls 13A, 13B in the stacking direction of the electrode plates 2 and 3 are more toward the inner side (inside of the frame 10) than the outer peripheral ends of the outer walls 13A, 13B. ) Concave shape. For example, as shown in FIG. 2 (a), FIG. 3 (b), and FIG. 4 (b), the non-contact recessed portion 21 is smaller than the outer peripheral end portion (both widthwise end portions) 13AX of the outer wall 13A , 13AY, and 13BX, 13BY, which are outer peripheral ends (both ends in the width direction) of the outer wall 13B, are concave shapes that are recessed more toward the inside (inside) of the frame body 10. That is, since the outer walls 13A and 13B do not have convex portions protruding outward, it is possible to suppress an increase in the volume of the single storage battery 1. Therefore, the non-contact recessed portion 21 provided in the frame body 10 of the present embodiment does not correspond to the space between the ribs when the convex rib portion is provided on the outer wall 20 of the frame body 10 as disclosed in Patent Document 1. Formation of depressions.
在電極板2、3的積層方向上相對向之對向外壁13A、13B的非接觸凹部21，沒有與鄰接的其他蓄電池1的框體10的外壁20嵌合。也就是說，非接觸凹部21，在藉由此非接觸凹部21形成的凹陷內，不具有與包含其他蓄電池1之電池組的任一個構件接觸的部位。因此，在非接觸凹部21內，能夠確保空洞，該空洞成為空氣的通道而用以散熱的空間。藉此，自框體10將熱量傳遞至此空洞的空間中包含的空氣，藉由此空氣在空洞中移動而可以進行散熱。因此，在本實施形態的框體10上設置的非接觸凹部21，不相當於為了使蓄電池1並排並使框體10的外壁彼此嵌合而形成在框體10的外壁上的凹凸形狀。The non-contact recessed portions 21 facing the outer walls 13A and 13B in the stacking direction of the electrode plates 2 and 3 are not fitted to the outer wall 20 of the frame body 10 of the other adjacent storage battery 1. That is, the non-contact recessed portion 21 does not have a portion in contact with any member of the battery pack including the other secondary battery 1 in the recess formed by the non-contact recessed portion 21. Therefore, a cavity can be secured in the non-contact recessed portion 21, and the cavity serves as a passage for air and a space for heat dissipation. Thereby, heat is transferred from the frame body 10 to the air contained in the hollow space, and thus the air can be dissipated by moving the air through the hollow space. Therefore, the non-contact recessed portion 21 provided in the housing 10 of this embodiment does not correspond to the uneven shape formed on the outer wall of the housing 10 in order to fit the battery 1 side by side and fit the outer walls of the housing 10 to each other.
在電極板2、3的積層方向上相對向之對向外壁13A、13B的非接觸凹部21，較佳是在平行於底壁11之橫剖面上，將外壁20的周邊(連接外周端部13AX與外周端部13AY之直線或連接外周端部13BX與外周端部13BY之直線)作為基準時，為以梯形狀、三角形狀或U字形狀凹陷的凹形狀。In the stacking direction of the electrode plates 2 and 3, the non-contact recessed portions 21 facing the outer walls 13A and 13B, preferably in a cross section parallel to the bottom wall 11, connect the periphery of the outer wall 20 (connecting the outer peripheral end portion 13AX). When the straight line with the outer peripheral end portion 13AY or the straight line connecting the outer peripheral end portion 13BX and the outer peripheral end portion 13BY is used as a reference, it is a concave shape recessed in a ladder shape, a triangular shape, or a U-shape.

In the housing 10 shown in FIG. 6, when the electrode plates 2 and 3 for a storage battery are housed in the housing 10, the pair of outward facing walls 13A and 13B facing the stacking direction of the electrode plates 2 and 3 are The flat wall has no non-contact recessed portion 21. The number given on the arrow indicating the range is the size (unit: mm), and R represents the radius of curvature (unit: mm). That is, the long side (equivalent to the width) of the cross section of the frame 10 shown in FIG. 6 (a) is 170 mm, the short side (equivalent to the depth) is 106 mm, the thickness of the outer wall is 5 mm, and the corner is the outer periphery. The curvature radius (R) of the arc of the end portion 13AX, 13AY, 13BX, and 13BY is 6 mm. In addition, as shown in FIG. 6 (b), the vertical view (equivalent height) of the front view of the frame 10 is 312 mm, and the corner of the outer wall 20 and the bottom wall 11 is the radius of curvature (R) of the arc of the side 11a. It is 6mm.
較佳是電池組用框體10，具有：底壁11；開口部12，其對向於此底壁11；及，外壁20，其自底壁11的周邊向前述開口部12的周邊延伸；其中，外壁20，在與底壁11平行的橫剖面上呈約略長方形，並具有成為長邊側之長邊側外壁和成為短邊側之短邊側外壁；前述長邊側外壁是在電極板2、3的積層方向上相對向之對向外壁13A、13B，並具備了在與鄰接的其他蓄電池1的框體10的外壁20之間形成空洞(未圖示)之非接觸凹部21。相較於短邊側外壁，長邊側外壁具有較大的面積。因此，雖然電池組用框體10，抵抗群壓的強度有變弱的傾向，但是藉由非接觸凹部21的配置而形成的凹形狀來補強，即便長邊側外壁受到來自框體10的內部之群壓也不容易變形。Preferably, the battery pack frame 10 includes: a bottom wall 11; an opening 12 facing the bottom wall 11; and an outer wall 20 extending from the periphery of the bottom wall 11 to the periphery of the opening 12; The outer wall 20 is approximately rectangular in a cross section parallel to the bottom wall 11 and has a long-side outer wall that becomes a long-side and a short-side outer wall that becomes a short-side; the long-side outer wall is on the electrode plate. The stacking directions of 2 and 3 are opposite to the outer walls 13A and 13B, and are provided with a non-contact recessed portion 21 that forms a cavity (not shown) between the outer wall 20 and the outer wall 20 of the frame body 10 of the other adjacent storage battery 1. Compared to the short side outer wall, the long side outer wall has a larger area. Therefore, although the battery pack housing 10 tends to be weaker in resistance to group pressure, it is reinforced by the concave shape formed by the arrangement of the non-contact recessed portions 21 even if the outer wall of the long side is received from the inside of the housing 10 The group pressure is not easily deformed.
較佳是電池組用框體10，是利用合成樹脂形成。在鉛蓄電池中，如後述，可以使用將稀釋硫酸(dilute sulfuric acid)利用純水(purified water)進行稀釋而成的電解液。此時，如果利用金屬來形成框體，則電解液可能會腐蝕框體。在本實施形態中，因為利用合成樹脂來形成電池組用框體10，所以即便使用硫酸電解液作成的電解液，也能夠確保耐腐蝕性。The battery pack frame 10 is preferably formed of a synthetic resin. In a lead storage battery, as described later, an electrolytic solution obtained by diluting dilute sulfuric acid with purified water can be used. At this time, if the frame is formed using a metal, the electrolyte may corrode the frame. In the present embodiment, since the battery pack frame 10 is formed by using a synthetic resin, even if an electrolytic solution made of a sulfuric acid electrolytic solution is used, corrosion resistance can be ensured.
＜＜第二實施形態＞＞：蓄電池 上述第一實施形態的電池組用框體10，例如，能夠適用於蓄電池1的框體10(電池槽)。以下，作為第二實施形態，針對具備上述第一實施形態的電池組用框體10之蓄電池1的一例進行說明。<< Second Embodiment>: Battery The battery pack casing 10 of the first embodiment described above can be applied to, for example, the casing 10 (battery tank) of the battery 1. Hereinafter, as a second embodiment, an example of the battery 1 including the battery pack frame 10 of the first embodiment will be described.
如第1圖所示，本實施形態的蓄電池1，具備上述第一實施形態的電池組用框體10。作為本實施形態的蓄電池1，例如，具備：電極板群，其使正極板2和負極板3隔著墊子狀隔片4而交互地積層，且同極性的電極板彼此連結來構成；電池組用框體10，其收納前述電極板群和電解液；以及，蓋子6，其具有連接至前述電極板群的正極板2之正極端子6a、連接至前述電極板群的負極板3之負極端子6b、及排氣孔6c，並覆蓋前述電池組用框體10的排氣孔6c；其中，例如，前述電極板群，具有使外壁(對向外壁13A、13B)對向地配置的構成，該外壁在電極板2、3的積層方向上具有框體10的非接觸凹部21。As shown in FIG. 1, the battery 1 of the present embodiment includes the battery pack frame 10 of the first embodiment described above. The battery 1 according to this embodiment includes, for example, an electrode plate group in which a positive electrode plate 2 and a negative electrode plate 3 are alternately laminated with a cushion-like spacer 4 interposed, and electrode plates of the same polarity are connected to each other to form a battery pack. A frame body 10 is used to store the electrode plate group and the electrolyte; and a cover 6 is provided with a positive terminal 6a connected to the positive plate 2 of the electrode plate group and a negative terminal connected to the negative plate 3 of the electrode plate group. 6b and the exhaust hole 6c, covering the exhaust hole 6c of the battery pack frame 10; for example, the electrode plate group has a configuration in which an outer wall (opposite to the outer walls 13A, 13B) is arranged to face each other, This outer wall has a non-contact recessed portion 21 of the frame body 10 in the lamination direction of the electrode plates 2 and 3.
作為本實施形態的蓄電池1，例如，液式鉛蓄電池(孔型，vent type)和閥控式(密封型，seal type)鉛蓄電池。當使用液式鉛蓄電池時，通常，在上述蓋子6的排氣孔6c上安裝有用以防止電解液的飛散等之過濾器(filter)(未圖示)。當使用閥控式鉛蓄電池時，在上述蓋子6的排氣孔6c上安裝控制閥(未圖示)，控制閥通常被密封，僅當內壓異常上升時，為了放出氣體而被打開。內壓，是指作為蓄電池1的充電反應的副反應之水的電解所產生的氣體，此時在成為電池槽之框體10中造成的壓力上升。雖然成為使氣體自排氣孔6c排出的機構，但是當過度充電時，氣體排出趕不上氣體產生，會使得成為電池槽之框體10內的壓力上升而產生內壓。As the storage battery 1 of this embodiment, for example, a liquid lead storage battery (vent type) and a valve-regulated (seal type) lead storage battery are used. When a liquid lead storage battery is used, a filter (not shown) for preventing scattering of the electrolytic solution and the like is generally installed in the exhaust hole 6c of the cover 6. When a valve-regulated lead-acid battery is used, a control valve (not shown) is installed in the exhaust hole 6c of the cover 6, and the control valve is usually sealed, and is opened only to release gas when the internal pressure rises abnormally. The internal pressure refers to a gas generated by the electrolysis of water that is a side reaction of the charging reaction of the battery 1. At this time, the pressure caused in the casing 10 serving as a battery tank rises. Although it is a mechanism for exhausting gas from the exhaust hole 6c, when the gas is overcharged, the gas exhaust cannot keep up with the generation of gas, which causes the pressure in the casing 10 that becomes the battery tank to rise and generate an internal pressure.
[閥控式鉛蓄電池] 上述第一實施形態的電池組用框體10，特別適用於閥控式鉛蓄電池。以下，作為第二實施形態的蓄電池1，針對使用上述第一實施形態的電池組用框體10之閥控式鉛蓄電池的一例進行說明。[Valve-regulated lead storage battery] The battery pack frame 10 of the first embodiment is particularly suitable for a valve-regulated lead storage battery.

The positive electrode plate 2 and the negative electrode plate 3 are used as a paste-type electrode plate that holds a paste-like active material in a casting grid or an expanding grid. The positive electrode plate 2 and the negative electrode plate 3 are mainly used as a positive electrode plate in which a core made of a lead alloy is woven through a glass fiber tube and filled with an active material, or a clad electrode plate may be used.
格子的材質，主原料是鉛，能夠在鉛中添加錫、鈣、銻等，特佳是使用鈣和錫。藉由添加鈣，能夠減少自體放電的比率，但是此時的問題是容易引起集電體的腐蝕，能夠藉由錫的添加來抑制此問題。The main material of the grid is lead. Tin, calcium, antimony, etc. can be added to the lead. Calcium and tin are particularly preferred. The addition of calcium can reduce the rate of self-discharge. However, the problem at this time is that it is easy to cause corrosion of the current collector, and this problem can be suppressed by the addition of tin.
糊式電極板，能夠比包覆式電極板更容易製造。糊狀活性物質的調製，例如以捏揉(knead)含有一氧化鉛之鉛粉、水、硫酸等(有時也會配合正極、負極的特性來添加切斷纖維(cut fiber)、碳粉末、木質素(lignin)、硫酸鋇、鉛丹(red lead))的方式製作，但是不特別受限於此。A paste-type electrode plate can be manufactured more easily than a clad-type electrode plate. For the preparation of pasty active materials, for example, knead of lead powder containing lead monoxide, water, sulfuric acid, etc. (sometimes, the characteristics of the positive electrode and the negative electrode may be added to add cut fiber and carbon powder) , Lignin, barium sulfate, red lead), but it is not particularly limited to this.
[隔片] 隔片4，存在於正極板2與負極板3之間，並防止正極與負極的短路。具體的隔片，例如能夠是聚乙烯、玻璃不織布、聚丙烯等材料所構成的多孔質片、及這些材料所構成的纖維的混織物等，但是不特別受限於此。[Separator] The separator 4 exists between the positive electrode plate 2 and the negative electrode plate 3 and prevents a short circuit between the positive electrode and the negative electrode. Specific separators can be, for example, porous sheets made of materials such as polyethylene, glass nonwoven fabric, polypropylene, etc., and fiber woven fabrics made of these materials, but are not particularly limited thereto.
[電解液] 電解液，例如是將稀釋硫酸利用純化水來稀釋，並調和成質量百分比濃度是約30質量百分比前後的電解液，也能夠考慮到電池容量和壽命等來調整成適當濃度的電解液。配合蓄電池所要求的特性，也可以加入硫酸鎂、矽膠(silica gel)等的添加劑。[Electrolyte] The electrolytic solution is, for example, diluted sulfuric acid with purified water and adjusted to a concentration of about 30% by mass. The electrolyte can also be adjusted to an appropriate concentration in consideration of battery capacity and life. liquid. In accordance with the required characteristics of the battery, additives such as magnesium sulfate and silica gel can also be added.
