Definitions

  • This application relates to the field of battery technology, and in particular to a battery and an electrical device.
  • a battery can include individual battery cells and a battery casing, with the individual battery cells housed within the casing.
  • a decrease in the insulation between charged structures (such as contacts) and non-charged conductive structures (such as end plates) within the battery can lead to dangerous accidents such as battery explosions.
  • the main technical problem addressed by this application is to provide a battery and an electrical device that solves the problem of reduced insulation between charged and non-charged conductive structures within the battery.
  • the battery includes a battery housing, an insulating adsorption component, and a battery module, wherein the battery module and the insulating adsorption component are both installed inside the battery housing; the insulating adsorption component is located on one side of the battery assembly of the battery module; the battery assembly includes multiple battery cells; the insulating adsorption component is configured to adsorb electrolyte and thermal runaway products released by at least one battery cell of the battery assembly.
  • the insulating adsorption component is in the shape of a plate, sheet, or block.
  • an insulating adsorption component adsorbs the electrolyte and thermal runaway products released by the battery cell, reducing the amount of electrolyte and thermal runaway products flowing into the battery module.
  • This ensures that the creepage distance between the charged structure (e.g., the electrode plate) and the uncharged conductive structure remains unchanged or slightly decreases.
  • This solves the problem of reduced insulation performance between the charged structure (e.g., the electrode plate) and the uncharged conductive structure (e.g., the end plate) within the battery due to the electrolyte and thermal runaway products being located between them.
  • the first direction intersects with the end plate of the battery module.
  • a first gap exists between the insulating adsorbent and the end plate of the battery module along the first direction. This prevents the insulating adsorbent from contacting the end plate, reducing the risk of short circuits between the electrolyte and thermal runaway products adsorbed by the insulating adsorbent and the end plate.
  • the first gap is greater than or equal to 5 mm. This results in a larger creepage distance between the insulating adsorption component and the end plate of the battery module, thus strengthening the insulation between them.
  • the insulating adsorption member is located only on one side of the first surface of the battery assembly; the first surface extends along a first direction and intersects the first side surface of the battery assembly; the first direction intersects the end plate of the battery module. Wherein, along the first direction, the insulating adsorption member extends beyond the first side surface of the battery assembly, or the insulating adsorption member is flush with the first side surface of the battery assembly.
  • the insulating adsorption component extends beyond the first side of the battery assembly, or the insulating adsorption component is flush with the first side of the battery assembly; this allows the insulating adsorption component to cover more battery cells, so that the insulating adsorption component can adsorb more electrolyte and thermal runaway products released by the battery cells, thereby reducing the amount of electrolyte and thermal runaway products in the battery module.
  • the insulating adsorption member is located between the first top surface of the battery assembly and the battery housing; along the height direction of the battery module, there is a second gap between the insulating adsorption member and the top conductive structure on the first top surface of the battery assembly.
  • the insulating adsorption component is located between the first top surface of the battery assembly and the battery housing. This allows the insulating adsorption component to quickly adsorb the electrolyte and thermal runaway products released from the safety valves of the individual battery cells, reducing the amount of electrolyte and thermal runaway products flowing into the battery module.
  • the second gap between the insulating adsorption component and the top conductive structure of the battery assembly prevents the insulating adsorption component from contacting the top conductive structure on the first top surface of the battery assembly, reducing the risk of short circuits between the electrolyte and thermal runaway products adsorbed by the insulating adsorption component and the top conductive structure on the first top surface of the battery assembly.
  • the second gap is greater than or equal to 1 mm. This results in a larger creepage distance between the insulating adsorption member and the top conductive structure on the first top surface of the battery assembly, thereby strengthening the insulation capability between the insulating adsorption member and the top conductive structure on the first top surface of the battery assembly.
  • the battery assembly comprises multiple battery cells divided into M battery cell assemblies; the M battery cell assemblies are arranged along the length of the battery cells; each battery cell assembly includes N battery cells, which are arranged along the width of the battery cells.
  • the insulating adsorption component includes M first adsorption portions; the M first adsorption portions are spaced apart along the length of the battery cells; each of the M first adsorption portions corresponds to one of the M battery cell assemblies, and the first adsorption portions cover the safety valves of the N battery cells in the battery cell assembly.
  • the M first adsorption portions are arranged at intervals along the length of the battery cell, resulting in a smaller total area of the insulating adsorption component formed by the M first adsorption portions. This saves material and reduces the cost of the insulating adsorption component.
  • the M first adsorption portions can adsorb the electrolyte and thermal runaway products released from the safety valves of all battery cells.
  • the insulating adsorption element can withstand temperatures above 300°C. After a single battery cell experiences thermal runaway, the electrolyte and thermal runaway products released from the safety valve are at high temperatures.
  • the high-temperature resistant insulating adsorption element can adsorb the high-temperature electrolyte and thermal runaway products.
  • the insulating adsorption element is disposed on the second side of the battery assembly; the second side of the battery assembly intersects with the end plate of the battery module. This allows the insulating adsorption element to adsorb a larger amount of electrolyte and thermal runaway products.
  • the second side of the battery assembly has no conductive structures, thereby reducing the difficulty of installing the insulating adsorption element.
  • the insulating adsorption element covers the entire second side of the battery assembly. This results in a larger volume of the insulating adsorption element and a stronger adsorption capacity, which is beneficial for absorbing more electrolyte and thermal runaway products from the battery cells.
  • an explosion-proof valve is provided on one side of the first side of the battery assembly; along the first direction and away from the explosion-proof valve, the adsorption performance of the insulating adsorption element decreases; the first direction intersects with the end plate of the battery module.
  • the adsorption capacity of the insulating adsorption component closer to the explosion-proof valve is greater than that of the insulating adsorption component farther from the explosion-proof valve, so that the insulating adsorption component closer to the explosion-proof valve can adsorb more of the electrolyte released from the safety valve of the battery cell and thermal runaway products.
  • the height of the insulating adsorption member gradually decreases along the first direction and away from the explosion-proof valve; the minimum height of the insulating adsorption member is greater than the height of the battery cell's casing insulating film.
  • the height of the insulating adsorption element gradually decreases, thus gradually reducing its adsorption performance.
  • the minimum height of the insulating adsorption element is greater than the height of the battery cell's casing insulating film, which reduces the risk of electrolyte and thermal runaway products directly contacting the casing insulating film.
  • the second top surface of the insulating adsorption member is a sloped or stepped surface with a gradually decreasing height. This allows the height of the insulating adsorption member to gradually decrease.
  • the insulating adsorption member includes N second adsorption portions, which are arranged along a first direction. Along the first direction, and in a direction away from the explosion-proof valve, the heights of the N second adsorption portions decrease sequentially.
  • N second adsorption parts can be assembled into an insulating adsorption component disposed on the second side. If any of the second adsorption parts is damaged, the damaged part can be replaced, thereby saving costs.
  • the battery assembly comprises multiple battery cells divided into M battery cell assemblies; the M battery cell assemblies are arranged along the length of the battery cells; each battery cell assembly includes N battery cells, which are arranged along the width of the battery cells; the width direction of the battery cells is a first direction.
  • the size of the second adsorption portion is equal to the size of the battery cell; and the N second adsorption portions are arranged in a one-to-one correspondence with the N battery cells of the outermost battery cell assembly of the M battery cell assembly.
  • the N second adsorption units are arranged one-to-one with the N battery cells of the outermost battery cell assembly of the M battery cell assembly, which makes the volume of the second adsorption units smaller; when it is necessary to replace the damaged second adsorption units, more costs can be saved.
  • the battery module further includes straps that secure the insulating adhesive element to a second side of the battery assembly.
  • the straps allow for quick and easy attachment of the insulating adhesive element to the second side of the battery assembly, thus integrating the insulating adhesive element with the battery assembly as a single unit.

  • an insulating adsorption element can adsorb the electrolyte and thermal runaway products released by the individual cells of two adjacent battery modules, and protect the second side of the battery module. This allows the side plates of the battery module to be removed, reducing the battery's weight.

In the event of thermal runaway in a battery cell, its safety valve releases electrolyte and thermal runaway products, which are the byproducts of a thermal reaction in the electrolyte. The released electrolyte and thermal runaway products flow into the battery casing, potentially causing explosions in charged structures within the battery (such as battery cells).

发明内容
本申请主要解决的技术问题是提供一种电池和用电设备，解决电池内的带电结构与不带电的导电结构之间的绝缘能力降低的问题。
为解决上述技术问题，本申请采用的第一个技术方案是：提供一种电池。电池包括电池箱体、绝缘吸附件和电池模组，电池模组和绝缘吸附件均安装在电池箱体内；绝缘吸附件位于电池模组的电池组件的一侧；电池组件包括多个电池单体；绝缘吸附件被配置为吸附电池组件的至少一个电池单体释放的电解液和热失控产物。绝缘吸附件的形状为板、片或块。
在本实施例中，在电池模组的电池单体发生热失控时，利用绝缘吸附件吸附电池单体释放的电解液和热失控产物，减少流动至电池模组内电池单体释放的电解液和热失控产物的量，使得带电结构(例如巴片)与不带电的导电结构之间的爬电距离保持不变或略微减小。从而解决了因电池单体释放的电解液和热失控产物位于电池内的带电结构(例如巴片)与不带电的导电结构(例如端板)之间，使得电池内的带电结构(例如巴片)与不带电的导电结构(例如端板)之间的绝缘性能降低的问题。
在一些实施例中，第一方向与电池模组的端板交叉。沿第一方向，绝缘吸附件与电池模组的端板之间存在第一间隙。可以使得绝缘吸附件不会接触到端板，减小绝缘吸附件吸附的电解液和热失控产物与端板短接的风险。
在一些实施例中，第一间隙大于或等于5mm。使得绝缘吸附件与电池模组的端板之间的爬电距离较大，使得绝缘吸附件与电池模组的端板之间的绝缘能力较强。
在一些实施例中，绝缘吸附件仅位于电池组件的第一表面的一侧；第一表面沿第一方向延伸，且与电池组件的第一侧面交叉；第一方向与电池模组的端板交叉。其中，沿第一方向，绝缘吸附件超出电池组件的第一侧面，或者绝缘吸附件与电池组件的第一侧面齐平。
在本实施例中，绝缘吸附件超出电池组件的第一侧面，或者绝缘吸附件与电池组件的第一侧面齐平；使得绝缘吸附件可以覆盖较多的电池单体，以便于绝缘吸附件可以吸附较多电池单体释放的电解液和热失控产物，减小电池模组内电解液和热失控产物的量。
在一些实施例中，绝缘吸附件位于电池组件的第一顶面与电池箱体之间；沿着电池模组的高度方向上，绝缘吸附件与电池组件的第一顶面上的顶部导电结构之间存在第二间隙。
在本实施例中，绝缘吸附件位于电池组件的第一顶面与电池箱体之间，使得绝缘吸附件可以较快的吸附电池单体的安全阀释放的电解液和热失控产物，减小电解液和热失控产物流动到电池模组内的量。绝缘吸附件与电池组件的顶部导电结构之间的第二间隙，可以使得绝缘吸附件不会接触到电池组件的第一顶面上的顶部导电结构，减小绝缘吸附件吸附的电解液和热失控产物与电池组件的第一顶面上的顶部导电结构短接的风险。
在一些实施例中，第二间隙大于或等于1mm。使得绝缘吸附件与电池组件的第一顶面上的顶部导电结构之间的爬电距离较大，使得绝缘吸附件与电池组件的第一顶面上的顶部导电结构之间的绝缘能力较强。

在本实施例中，M个第一吸附部沿电池单体的长度方向间隔排布，使得M个第一吸附部构成的绝缘吸附件的总面积较小，从而节约了绝缘吸附件的材料，降低了绝缘吸附件的成本。利用M个第一吸附部可以吸附所有电池单体的安全阀释放的电解液和热失控产物。
在一些实施例中，绝缘吸附件能够承受300℃以上的温度。在电池单体发生热失控后，由于从安全阀释放的电解液和热失控产物的温度较高，利用耐高温的绝缘吸附件可以吸附温度较高的电解液和热失控产物。
在一些实施例中，绝缘吸附件设置在电池组件的第二侧面上；电池组件的第二侧面与电池模组的端板交叉。有利于绝缘吸附件可以吸附较多的电解液和热失控产物。电池组件的第二侧面上没有导电结构，从而减小绝缘吸附件的安装难度。
在一些实施例中，绝缘吸附件覆盖电池组件的整个第二侧面。使得绝缘吸附件的体积较大，绝缘吸附件的吸附能力较强，有利于吸收较多电池单体的电解液和热失控产物。
在一些实施例中，位于电池组件的第一侧面的一侧设置有防爆阀；沿第一方向，且远离防爆阀的方向上，绝缘吸附件的吸附性能减小；第一方向与电池模组的端板交叉。
在本实施例中，绝缘吸附件靠近防爆阀一侧的吸附能力大于绝缘吸附件远离防爆阀一侧的吸附能力，使得靠近防爆阀一侧的绝缘吸附件可可以更多的吸附电池单体的安全阀释放电解液和热失控产物。
在一些实施例中，沿第一方向，且远离防爆阀的方向上，绝缘吸附件的高度逐渐减小；绝缘吸附件的最小高度大于电池单体的壳体绝缘膜的高度。
在本实施例中，沿第一方向，且远离防爆阀的方向上，绝缘吸附件的高度逐渐减小，使得绝缘吸附件的吸附性能逐渐减小。绝缘吸附件的最小高度大于电池单体的壳体绝缘膜的高度，可以减小电解液和热失控产物直接接触到壳体绝缘膜的风险。
在一些实施例中，沿第一方向，且远离防爆阀的方向上，绝缘吸附件的第二顶面为高度逐渐减小的斜面或阶梯面。可以使得绝缘吸附件的高度逐渐减小。
在一些实施例中，绝缘吸附件包括N个第二吸附部，N个第二吸附部沿与第一方向排布。沿第一方向，且远离防爆阀的方向上，N个第二吸附部的高度依次减小。
在本实施例中，利用N个第二吸附部可以拼成一个设置在第二侧面上的绝缘吸附件。在任意的第二吸附部出现损毁时，可以将出现损毁的第二吸附部进行更换，从而节约了成本。
在一些实施例中，电池组件的多个电池单体划分为M个电池单体组件；M个电池单体组件沿电池单体的长度方向排布；电池单体组件包括N个电池单体，N个电池单体沿电池单体的宽度方向排布；电池单体的宽度方向为第一方向。沿电池单体的宽度方向，第二吸附部的尺寸等于电池单体的尺寸；且N个第二吸附部与M个电池单体组件的最边缘电池单体组件的N个电池单体一一对应设置。
在本实施例中，N个第二吸附部与M个电池单体组件的最边缘电池单体组件的N个电池单体一一对应设置，使得第二吸附部的体积较小；在需要将损毁的第二吸附部进行更换时，可以节约了更多的成本。
在一些实施例中，电池模组还包括绑带，绑带将绝缘吸附件捆绑在电池组件的第二侧面上。利用绑带可以快速的将绝缘吸附件固定在电池组件的第二侧面上，从而使得绝缘吸附件与电池组件形成一个整体。
在一些实施例中，电池模组的数量为多个，相邻的两个电池模组的电池组件的第二侧面之间设置一个绝缘吸附件，且与第二侧面接触；电池组件的第二侧面与电池模组的端板交叉。
在本实施例中，利用一个绝缘吸附件可以吸附相邻两个电池模组的电池组件的电池单体释放的电解液和热失控产物，以及保护电池组件的第二侧面。从而可以去除电池模组的侧板，以减轻电池的重量。

具体实施方式
下面结合说明书附图，对本申请实施例的方案进行详细说明。
以下描述中，为了说明而不是为了限定，提出了诸如特定系统结构、接口、技术之类的具体细节，以便透彻理解本申请。
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本申请的一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请中的术语“第一”、“第二”、“第三”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”、“第三”的特征可以明示或者隐含地包括至少一个该特征。本申请的描述中，“多个”的含义是至少两个，例如两个，三个等，除非另有明确具体的限定。本申请实施例中所有方向性指示(诸如上、下、左、右、前、后……)仅用于解释在某一特定姿态(如附图所示)下各部件之间的相对位置关系、运动情况等，如果该特定姿态发生改变时，则该方向性指示也相应地随之改变。此外，术语“包括”和“具有”以及它们任何变形，意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、系统、产品或设备没有限定于已列出的步骤或单元，而是可选地还包括没有列出的步骤或单元，或可选地还包括对于这些过程、方法、产品或设备固有的其它步骤或单元。

目前，从市场形势的发展来看，储能及动力电池的应用越加广泛。储能及动力电池不仅被应用于水力、火力、风力和太阳能电站等储能电源系统，而且还被广泛应用于电动自行车、电动摩托车、电动汽车等电动交通工具，以及航空航天等多个领域。随着储能及动力电池应用领域的不断扩大，其市场的需求量也在不断地扩增。
本发明人注意到，随着储能及动力电池使用时间变长，电池可能发生爆炸等危险事故。
为了减小电池发生爆炸的可能性，申请人研究发现，可以在电池单体外侧设置绝缘吸附件。这是因为，电池通常包括电池单体和电池箱体，电池单体安装在电池箱体内。在电池单体发生热失控后，该电池单体的安全阀会释放出电解液和热失控产物，热失控产物为电解液发生热反应后的产物。释放的电解液和热失控产物流动到电池箱体内，使得电池内的带电结构(例如巴 片、电路板等)与不带电的导电结构(例如端板、电池箱体)之间的爬电距离缩短，从而导致带电结构与不带电的导电结构之间的绝缘能力降低，使得电池发生爆炸等危险事故。其中带电结构可以理解为带电的导电结构。
为了解决电池内的带电结构(例如巴片)与不带电的导电结构(例如端板)之间的绝缘能力降低的问题，本申请的实施例提供一种电池，电池包括电池箱体和电池模组，电池模组安装在电池箱体内；电池模组包括电池组件、绝缘吸附件和绝缘吸附件，绝缘吸附件位于电池模组的电池组件的一侧。绝缘吸附件的形状为板、片或块。电池单体在发生热失控后，利用绝缘吸附件吸附电池单体释放的电解液和热失控产物，减少流动至电池模组内电池单体释放的电解液和热失控产物的量，使得电池内的带电结构(例如巴片)与不带电的导电结构(例如端板)之间的爬电距离保持不变或略微减小。从而解决了因电池单体释放的电解液和热失控产物位于电池内的带电结构(例如巴片)与不带电的导电结构(例如端板)之间，使得电池内的带电结构(例如巴片)与不带电的导电结构(例如端板)之间的绝缘性能降低的问题。

在一些示例中，绝缘吸附件11位于电池模组1的电池组件12的一侧，且与电池组件12的表面接触；即绝缘吸附件11位于电池组件12的表面上。该电池组件12的表面包括上述电池组件12的第一顶面125、第一底面123、第一侧面122和第二侧面124中的至少一者。例如电池组件12的表面可以是电池组件12的第一顶面125，绝缘吸附件11位于电池组件12的第一顶面125上。又例如电池组件12的表面可以是电池组件12的第一侧面122，绝缘吸附件11位于电池组件12的第一侧面122上。又例如电池组件12的表面可以是电池组件12的第二侧面124，绝缘吸附件11位于电池组件12的第二侧面124上。又例如电池组件12的表面可以是电池组件12的第一顶面125和第一侧面122，绝缘吸附件11位于电池组件12的第一顶面125上，且绝缘吸附件11位于电池组件12的第一侧面122上；此时绝缘吸附件11的数量可以一个，一个绝缘吸附件11的一部分位于电池组件12的第一顶面125，另一部分弯折后位于第一侧面122上；当然绝缘吸附件11的数量可以是多个，例如两个绝缘吸附件11，一个绝缘吸附件11位于电池组件12的第一顶面125上，另一个绝缘吸附件11位于电池组件12的第一侧面122上。
在另一些示例中，电池模组1不包含顶板和侧板，绝缘吸附件11位于电池模组1的电池组件12的一侧，且与电池组件12的表面间隔设置，绝缘吸附件11与电池箱体2的内表面接触连接，例如绝缘吸附件11与电池箱体2的内侧面和/或内顶面接触连接。在另一些示例中，在电池模组1可以包括顶板和侧板，绝缘吸附件11位于电池模组1的电池组件12的一侧，且与电池组件12的表面间隔设置，绝缘吸附件11与侧板和/或顶板接触连接，此时绝缘吸附件11不位于电池组件12的表面上，也不位于电池箱体2的内表面上。
在一些示例中，绝缘吸附件11的数量为多个(例如两个、八个等)，电池模组1的数量为多个，多个电池模组1与多个绝缘吸附件11一一对应设置；一个绝缘吸附件11位于一个电池模组1的电池组件12的一侧。其中，多个绝缘吸附件11之间可以连接成一个整体，当然多个绝缘吸附件11之间也可以是独立分开设置。在另一些示例中，绝缘吸附件11的数量为一个，电池模组1的数量为多个，一个绝缘吸附件11位于所有电池模组1的电池组件12的一侧，一个绝缘吸附件11与多个电池模组1对应设置。在另一些示例中，绝缘吸附件11的数量为一个，电池模组1的数量为一个，一个绝缘吸附件11位于一个电池模组1的电池组件12的一侧。
绝缘吸附件11可以是具有吸附能力和绝缘能力的结构；例如绝缘吸附件11可以是多孔基体，多孔基体的材料可以是陶瓷、玻璃或硅胶等。又例如绝缘吸附件11可以是泡绵或海绵等。绝缘吸附件11可以是板、片或块等形状；其中，板的厚度大于片的厚度，且小于块的厚度。这样一来，便于安装绝缘吸附件11。绝缘吸附件11可以是一个整体结构，即一体成型结构；例如绝缘吸附件11可以是板。绝缘吸附件11还可以由多个结构拼接而成的拼接结构，例如绝缘吸附件11由多个下文中的第二吸附部112拼接而成。
在本实施例中，在电池模组1的电池单体121发生热失控时，利用绝缘吸附件11吸附电池单体121释放的电解液和热失控产物，减少流动至电池模组1内电池单体121释放的电解液和热失控产物的量，使得带电结构(例如巴片)与不带电的导电结构(例如端板)之间的爬电距离保持不变或略微减小。从而解决了因电池单体121释放的电解液和热失控产物位于带电结构 (例如巴片)与不带电的导电结构(例如端板)之间，使得带电结构(例如巴片)与不带电的导电结构(例如端板)之间的绝缘性能降低的问题。
在一些实施例中，参见图5，沿第一方向X，绝缘吸附件11与电池模组1的端板13之间存在第一间隙d1；第一方向X与电池模组1的端板13交叉。
由于端板13的数量有两个，因此绝缘吸附件11与两个端板13之间均存在第一间隙d1。
在一些示例中，端板13的全部可以是导电结构。在另一些示例中，端板13的一部分可以是导电结构，另一部分可以绝缘结构。
在本实施例中，绝缘吸附件11与电池模组1的端板13之间存在第一间隙，可以使得绝缘吸附件11不会接触到端板13，减小绝缘吸附件11吸附的电解液和热失控产物之后与端板13短接的风险。
在一些实施例中，第一间隙d1大于或等于5mm。
例如第一间隙的间距可以为5mm、6mm、7mm、8mm、9mm、10mm、11mm、12mm、15mm、20mm、30mm、50mm、100mm等。
在本实施例中，第一间隙d1大于或等于5mm，使得绝缘吸附件11与电池模组1的端板13之间的爬电距离较大，使得绝缘吸附件11与电池模组1的端板13之间的绝缘能力较强。
在一些实施例中，绝缘吸附件11仅位于电池组件12的第一表面126的一侧；第一表面126沿第一方向X延伸，且与电池组件12的第一侧面122交叉；第一方向X与电池模组1的端板13交叉；沿第一方向X，绝缘吸附件11超出电池组件12的第一侧面122，或者绝缘吸附件11与电池组件12的第一侧面122齐平。
绝缘吸附件11仅位于电池组件12的第一表面126的一侧，是指绝缘吸附件11不位于电池组件12的第一侧面122的一侧。第一表面126沿第一方向X延伸，可以理解为第一表面126与第一方向X平行。在一些示例中，电池组件12的第一表面126可以包括电池组件12的第一顶面125、第二侧面124和第一底面123中的至少一者；例如电池组件12的第一表面126为电池组件12的第一顶面125；又例如电池组件12的第一表面126为第一底面123；又例如电池组件12的第一表面126为第二侧面124；又例如电池组件12的第一表面126包括电池组件12的第一顶面125和第二侧面124；又例如电池组件12的第一表面126包括电池组件12的第一顶面125、第二侧面124和第一底面123。
第一表面126与电池组件12的第一侧面122交叉；例如第一表面126与电池组件12的第一侧面122垂直。电池组件12的第一侧面122与第一方向X垂直，且第一方向X与端板13垂直，此时第一侧面122与端板13平行。
沿第一方向X，绝缘吸附件11超出电池组件12的第一侧面122，可以理解为，沿第一方向X，绝缘吸附件11的尺寸大于第一表面126的尺寸。沿第一方向X，绝缘吸附件11与电池组件12的第一侧面122齐平；可以理解为，沿第一方向X，绝缘吸附件11的尺寸等于第一表面126的尺寸。
在本实施例中，绝缘吸附件11超出电池组件12的第一侧面122，或者绝缘吸附件11与电池组件12的第一侧面122齐平；使得绝缘吸附件11可以覆盖较多的电池单体121，以便于绝缘吸附件11可以吸附较多电池单体121释放的电解液和热失控产物，减小电池模组1内电解液和热失控产物的量。
在一些实施例中，参见图6，绝缘吸附件11位于电池组件12的第一顶面125与电池箱体2 之间；沿着电池模组1的高度方向上，绝缘吸附件11与电池组件12的第一顶面125上的顶部导电结构之间存在第二间隙d2。
电池组件12的第一顶面125上设置有巴片、电路板等顶部导电结构，也就是说，巴片、电路板等顶部导电结构安装在电池组件12的第一顶面125上。其中，顶部导电结构包括带电结构和/或不带电的导电结构。
在一些示例中，在电池模组1包括顶板，绝缘吸附件11设置在电池模组1的顶板上，此时，绝缘吸附件11和顶板的整体位于电池箱体2与电池组件12的第一顶面125之间。例如绝缘吸附件11螺栓或卡扣等可拆卸设置在电池模组1的顶板上。在另一些示例中，在电池模组1不包括顶板，绝缘吸附件11设置在电池箱体2的内顶面上，此时，绝缘吸附件11位于电池箱体2的内顶面与电池组件12的第一顶面125之间。例如绝缘吸附件11螺栓或卡扣等可拆卸设置在电池箱体2的内顶面上。
在电池组件12的第一顶面125上的顶部导电结构为多个，绝缘吸附件11与电池组件12的第一顶面125上的顶部导电结构之间存在第二间隙d2，是指绝缘吸附件11与电池组件12的第一顶面125上的所有顶部导电结构之间存在第二间隙d2，即绝缘吸附件11与电池组件12的第一顶面125上的所有顶部导电结构均不接触。
在本实施例中，绝缘吸附件11位于电池组件12的第一顶面125与电池箱体2之间，使得绝缘吸附件11可以较快的吸附电池单体121的安全阀1214释放的电解液和热失控产物，减小电解液和热失控产物流动到电池模组1内的量。绝缘吸附件11与电池组件12的顶部导电结构之间的第二间隙d2，可以使得绝缘吸附件11不会接触到电池组件12的第一顶面125上的顶部导电结构，减小绝缘吸附件11吸附的电解液和热失控产物与电池组件12的第一顶面125上的顶部导电结构短接的风险。
在一些实施例中，第二间隙d2大于或等于1mm。
第二间隙d2的间距为1mm、2mm、3mm、4mm、5mm、6mm、7mm、8mm、9mm、10mm、11mm、12mm、15mm、20mm、30mm、50mm、100mm等。
在本实施例中，第二间隙d2大于或等于1mm，使得绝缘吸附件11与电池组件12的第一顶面125上的顶部导电结构之间的爬电距离较大，使得绝缘吸附件11与电池组件12的第一顶面125上的顶部导电结构之间的绝缘能力较强。
在一些实施例中，参见图4和图7，电池组件12的多个电池单体121划分为M个电池单体组件127；M个电池单体组件127沿电池单体121的长度方向排布；电池单体组件127包括N个电池单体121，N个电池单体121沿电池单体121的宽度方向排布。绝缘吸附件11包括M个第一吸附部111；M个第一吸附部111与M个电池单体组件127一一对应设置，且第一吸附部111覆盖电池单体组件127的N个电池单体121的安全阀1214。
第一方向X为电池单体121的宽度方向，即电池单体121的宽度方向与端板13交叉。第一吸附部111的形状可以是长条形状，此时第一吸附部111的长边与电池单体121的宽度方向平行。
在本实施例中，M个第一吸附部111沿电池单体121的长度方向间隔排布，使得M个第一吸附部111构成的绝缘吸附件11的总面积较小，从而节约了绝缘吸附件11的材料，降低了绝缘吸附件11的成本。利用M个第一吸附部111可以吸附所有电池单体121的安全阀1214释放的电解液和热失控产物。
在一些实施例中，绝缘吸附件11能够承受300℃以上的温度。
绝缘吸附件11可以是耐高温结构，耐高温结构能够承受300℃以上的温度，即电池单体121的温度高于300℃时，绝缘吸附件11不会燃烧或熔化，可以吸附电解液和热失控产物。耐高温结构低于300℃可以正常使用。
在本实施例中，在电池单体121发生热失控后，由于从安全阀1214释放的电解液和热失控产物的温度较高，利用耐高温的绝缘吸附件11可以吸附温度较高的电解液和热失控产物。
在一些实施例中，参见图8，绝缘吸附件11设置在电池组件12的第二侧面124上；电池组件12的第二侧面124与电池模组1的端板13交叉。
利用绑带、胶带、胶水等，将绝缘吸附件11设置在电池组件12的第二侧面124上。绝缘吸附件11可以覆盖电池组件12的整个第二侧面124。绝缘吸附件11也可以覆盖电池组件12的第二侧面124的一部分，第二侧面124的另一部分没有被绝缘吸附件11覆盖。
在一些示例中，电池模组1包括侧板，绝缘吸附件11设置在第二侧面124上；使得绝缘吸附件11位于电池组件12的第二侧面124与侧板之间。在另一些示例中，电池模组1不包括侧板，绝缘吸附件11设置在第二侧面124上，使得绝缘吸附件11位于第二侧面124与电池箱体2的内侧面之间；该绝缘吸附件11可以吸附电池单体121的安全阀1214释放的电解液和热失控产物，使得该绝缘吸附件11还可以起到保护电池组件12的第二侧面124的作用(即起到与侧板的保护电池组件12相同的作用)。
在电池单体121发生热失控后，热失控的电池单体121释放的电解液和热失控产物的部分温度会被电池模组1内的其他结构(例如没有发生热失控的电池单体121，又例如电池箱体2)吸收，使得流动到电池组件12的第二表面的电解液和热失控产物的温度会降低。因此设置在第二侧面124上的绝缘吸附件11可以不是耐高温结构。当然设置在第二侧面124上的绝缘吸附件11可以上述的耐高温结构。
在本实施例中，绝缘吸附件11设置在电池组件12的第二侧面124上，有利于绝缘吸附件11可以吸附较多的电解液和热失控产物。电池组件12的第二侧面124上没有导电结构，从而减小绝缘吸附件11的安装难度。
在一些实施例中，绝缘吸附件11覆盖电池组件12的整个第二侧面124。
绝缘吸附件11覆盖电池组件12的整个第二侧面124，可以理解为，绝缘吸附件11在第二侧面124的正投影覆盖整个第二侧面124。
在本实施例中，绝缘吸附件11覆盖电池组件12的整个第二侧面124，使得绝缘吸附件11的体积较大，绝缘吸附件11的吸附能力较强，有利于吸收较多电池单体121的电解液和热失控产物。
在一些实施例中，参见图9～图12，位于电池组件12的第一侧面122的一侧设置有防爆阀15；沿第一方向X，且远离防爆阀15的方向上，绝缘吸附件11的吸附性能减小；第一方向X与电池模组1的端板13交叉。
参见图9，在防爆阀15的数量为一个时，沿第一方向X，且远离防爆阀15的方向上，可以是指沿着第一方向X，并且由设置有防爆阀15的第一侧面122指向没有设置防爆阀15的第一侧面122的方向上；例如该方向为如图9示出的第一方向X的箭头方向。其中，沿该方向，绝缘吸附件11件的吸附性能一直减小，不会出现增大的情况。
参见图11，在防爆阀15的数量为两个时，沿第一方向X，且远离防爆阀15的方向上，可 以是指沿第一方向X，并且由设置有防爆阀15的第一侧面122指向电池组件12的中部的方向上；例如该方向为如图11示出的第一方向X的箭头方向和反方向的双向方向。其中，沿着该方向，绝缘吸附件11件的吸附性能先减小后增大。当然，在防爆阀15的数量为两个时，沿第一方向X，且远离防爆阀15的方向上，可以是指沿第一方向X，且由设置有一个防爆阀15的第一侧面122指向设置有另一个防爆阀15的第一侧面122的方向上；例如该方向为如图11示出的第一方向X的箭头方向。其中，沿该方向，绝缘吸附件11件的吸附性能一直减小，不会出现增大的情况。
本下文中，以防爆阀15的数量为一个时，沿第一方向X，且远离防爆阀15的方向上，可以是指沿着第一方向X，并且由设置有防爆阀15的第一侧面122指向没有设置防爆阀15的第一侧面122的方向上为例进行说明。其中，例如防爆阀15可以设置在端板13上。
绝缘吸附件11的吸附性能的大小由绝缘吸附件11的参数决定的，绝缘吸附件11的参数可以包括绝缘吸附件11的高度、厚度、材料等中的至少一者。在一些示例中，通过改变绝缘吸附件11的高度可以改变绝缘吸附件11的吸附性能的大小。例如，沿第一方向X，且远离防爆阀15的方向上，绝缘吸附件11的高度减小，使得绝缘吸附件11在该方向上的吸附性能减小。在另一些示例中，通过改变绝缘吸附件11的厚度可以改变绝缘吸附件11的吸附性能的大小。例如，沿第一方向X，且远离防爆阀15的方向上，绝缘吸附件11的厚度减小，使得绝缘吸附件11在该方向上的吸附性能减小。下文中以沿第一方向X，且远离防爆阀15的方向上，绝缘吸附件11的高度减小，使得绝缘吸附件11在该方向上的吸附性能减小为例进行说明。
在本实施例中，绝缘吸附件11靠近防爆阀15一侧的吸附能力大于绝缘吸附件11远离防爆阀15一侧的吸附能力，使得靠近防爆阀15一侧的绝缘吸附件11可以更多的吸附电池单体121的安全阀1214释放电解液和热失控产物。
在一些实施例中，参见图9～图12，沿第一方向X，且远离防爆阀15的方向上，绝缘吸附件11的高度逐渐减小；绝缘吸附件11的最小高度大于电池单体121的壳体绝缘膜1237的高度。
参见图3，电池单体121还可以包括壳体绝缘膜1237，壳体绝缘膜1237包覆在壳体1236的外面，起到保护壳体1236的作用。
绝缘吸附件11具有沿第三方向Z相对的第二顶面和第二底面。绝缘吸附件11的高度逐渐减小可以理解为，沿第一方向X，绝缘吸附件11的第二顶面和第二底面之间沿第三方向Z的距离逐渐减小。在一些示例中，绝缘吸附件11的第二底面为平面，绝缘吸附件11的第二顶面为非平面(例如倾斜曲面、倾斜平面或阶梯面)，使得绝缘吸附件11的高度逐渐减小。当然绝缘吸附件11的第二顶面和第二底面均可以为非平面，也使得绝缘吸附件11的第二顶面和第二底面之间的距离逐渐减小。本文以缘吸附件的第二底面为平面，绝缘吸附件11的第二顶面为非平面为例进行说明。
在防爆阀15的数量为一个时，沿第一方向X，且远离防爆阀15的方向上，绝缘吸附件11的高度逐渐减小，且不增大。
在本实施例中，沿第一方向X，且远离防爆阀15的方向上，绝缘吸附件11的高度逐渐减小，使得绝缘吸附件11的吸附性能逐渐减小。绝缘吸附件11的最小高度大于电池单体121的壳体绝缘膜1237的高度，可以减小电解液和热失控产物直接接触到壳体绝缘膜1237的风险。
此外，由于绝缘吸附件11的高度逐渐减小，使得绝缘吸附件11覆盖第二侧面124的一部分，第二侧面124的另一部分暴露着；从而绝缘吸附件11可以吸附电池单体121释放的电解液 和热失控产物，同时还节约了成本。
在一些实施例中，沿第一方向X，且远离防爆阀15的方向上，绝缘吸附件11的第二顶面为高度逐渐减小的斜面或阶梯面。
参见图10，斜面可以是斜曲面，例如斜曲面还可以是凹陷的斜曲面；又例如斜曲面可以是凸起的斜曲面。斜面还可以是如图9示出的斜平面。
由于片和膜等的厚度可以忽略不计，在绝缘吸附件11可以是片或膜较薄的结构时，上述绝缘吸附件11的顶面可以称为绝缘吸附件11的顶边。
在本实施例中，绝缘吸附件11的第二顶面为高度逐渐减小的斜面或阶梯面，以使得绝缘吸附件11的高度逐渐减小。
在一些实施例中，参见图12，绝缘吸附件11包括N个第二吸附部112，N个第二吸附部112沿与第一方向X排布；沿第一方向X，且远离防爆阀15的方向上，N个第二吸附部112的高度依次减小。
在一些示例中，第二吸附部112的顶面和底面均为平面，多个第二吸附部112的底面齐平，N个第二吸附部112的高度依次减小，可以使得N个第二吸附部112的顶面和部分侧面构成阶梯面。
在本实施例中，利用N个第二吸附部112可以拼成一个设置在第二侧面124上的绝缘吸附件11。在任意的第二吸附部112出现损毁时，可以将出现损毁的第二吸附部112进行更换，从而节约了成本。
在一些实施例中，参见图12，电池组件12的多个电池单体121划分为M个电池单体组件127；M个电池单体组件127沿电池单体121的长度方向排布；电池单体组件127包括N个电池单体121，N个电池单体121沿电池单体121的宽度方向排布；电池单体121的宽度方向为第一方向X。N个第二吸附部112与M个电池单体组件127的最边缘电池单体组件的N个电池单体121一一对应设置。
在一些示例中，沿电池单体121的宽度方向，电池单体组件127的N个电池单体121之间存在第三间隙；沿电池单体121的宽度方向，第二吸附部112的尺寸为电池单体121的尺寸和第三间隙的尺寸之和。在一些示例中，沿电池单体121的宽度方向，电池单体组件127的N个电池单体121之间相互接触(即没有第三间隙)；沿电池单体121的宽度方向，第二吸附部112的尺寸等于电池单体121的尺寸。
在本实施例中，N个第二吸附部112与M个电池单体组件127的最边缘电池单体组件的N个电池单体121一一对应设置，使得第二吸附部112的体积较小；在需要将损毁的第二吸附部112进行更换时，可以节约了更多的成本。
在一些实施例中，电池模组1还包括绑带，绑带将绝缘吸附件11捆绑在电池组件12的第二侧面124上。
绑带可以钢带、塑料带等。绑带的数量可以是一个或多个。在一些示例中，利用绑带，将电池组件12、端板13和绝缘吸附件11捆绑成一个整体。
在本实施例中，利用绑带可以快速的将绝缘吸附件11固定在电池组件12的第二侧面124上。
在一些实施例中，电池模组1的数量为多个，相邻的两个电池模组1的电池组件12的第二侧面124之间设置一个绝缘吸附件11，且与第二侧面124接触；电池组件12的第二侧面124 与电池模组1的端板交叉。
在本实施例中，电池模组1没有侧板，使得一个绝缘吸附件11与相邻两个电池模组1的电池组件12的第二侧面124接触连接。最外侧的电池模组1的电池组件12的第二侧面124也可以设置绝缘吸附件11。
在本实施例中，利用一个绝缘吸附件11可以吸附相邻两个电池模组1的电池组件12的电池单体释放的电解液和热失控产物，以及保护电池组件12的第二侧面124。从而可以去除电池模组1的侧板，以减轻电池的重量。
