본 고안은 동을 집전용격자체()에 사용된 연축전지용 극판에 관한 것이다.The present invention is a copper collector grid ( It relates to a pole plate for lead-acid battery used in the).
종래에 알려진 연축전지로서는 일본국 실개평 1-100367호와 일본국 특개소 60-65450호가 있는데 이것들의 세파레타 단부와 세파레타를 주머니 형태로 구성할 때 양측의 철하는 부분이 본원 고안의 연(鉛)합금보호체와 유사한 것처럼 보여지게 되여 있으나, 이들의 구조의 구성과는 전혀 상이한 것이고, 또다른 종래의 연축전지용 극판의 집전용격자체에는 일반적으로 연합금이 사용되었다.Conventionally known lead-acid batteries include Japanese Patent Application Laid-Open No. 1-100367 and Japanese Patent Application Laid-Open No. 60-65450. When these Separetta ends and Separettas are configured in the form of a bag, the slit portions of both sides of the lead-acid battery are designed according to the present invention. I) It is shown to be similar to the alloy protector, but is completely different from the structure of these structures, and alloy is generally used for the current collector lattice of another conventional lead-acid battery plate.
그러나 연합금으로 된 격자체의 극판에 사용된 연축전지로서는 연합금의 전기저항이 약 21μΩ-㎝로서 조금 높으므로 대전류로 방전하면 격자의 저항에 의한 오믹(ohmic)한 저항분극이 크게되여 방전 전압의 저하가 증가되고, 연합금의 비중도 약 11로 되여 무거움으로 중량효율이 좋지않은 결점이 있었다.However, the lead-acid battery used in the electrode plate of the alloyed lattice body is about 21μΩ-cm, which is slightly higher, so when discharging with a large current, the ohmic resistance polarization caused by the lattice resistance becomes large, and the discharge voltage The increase in deterioration and the specific gravity of the alloy was about 11, which was heavy and had a disadvantage of poor weight efficiency.
여기서 연합금보다 전기 전도성이 좋은 동을 격자체에 사용하는 것이 제안되여 제7도에 표시한 바와같은 동으로 된 엑스팬드메탈(expanded metal)을 격자체로하여 사용한 극판이 사용하게 되였다.Here, it is proposed to use copper having better electrical conductivity than the alloy for the lattice, and an electrode plate using an expanded metal made of copper as the lattice as shown in FIG. 7 is used.
제7도에 있어서(1)을 연합금으로 된 집전용의 극판귀(耳)부, (2)는 동으로 된 엑스팬드메탈에 연 또는 연-석계합금의 도금이 된 격자체, (3)은 부극활물질(4)는 하부연결체이다. 여기서 격자체(2)에 있어서 연 또는 연-석계 합금의 도금을 한 것은 동이 전지의 전해액중에 용출(溶出)되여 자기방전의 증가 용량저하, 충전효율의 악화등을 일으키는 까닭이다. 그러나 연의 도금층은 부드러우므로 후 공정의 연도(練塗) 및 화성에 있어서 특히 격자체(2)의 측부의 도금층이 상하여 동이 노출되는 문제가 생겼으며, 격자체(2)의 측부는 요철상으로 되여있으므로 측부에 부착한 활물질(3)이 전지 사용중에 탈락하여 스폰지상으로 되여 단락(短絡)이 생기도록 하고 전지 수명이 조기에 다하여지는 문제가 있었다.In Fig. 7, (1) the pole pins for collectors made of allied alloy, (2) the lattice bodies in which lead metals are plated with lead or soft-stone alloys, (3) The silver negative electrode active material 4 is a lower linkage body. The reason why the lattice 2 is plated with a soft or soft-stone alloy is because copper is eluted in the electrolyte of the battery, causing an increase in the self-discharge and a decrease in the charging efficiency. However, since the lead plating layer is soft, there is a problem that copper is exposed due to the damage of the plating layer on the side of the lattice 2, particularly in the ductility and chemical conversion of the post-process, and the side of the lattice 2 is uneven. As a result, the active material 3 adhering to the side drops out during use of the battery, becomes a sponge, causing short circuiting, and shortening the battery life.
이 단락을 방지하기 위하여 측부에 부착한 활물질(3)을 후공정에서 빼고 실시되는 경우가 있으나 이럴 경우에는 공정수가 증가하고 도금층을 손상시켜 동을 노출시키는 등의 문제가 있었고, 제7도에 표시한 바와 같은 종래 것의 극판은 동 엑스팬드메탈을 연 또는 연-석계 합금으로 도포한 후 극판귀부(1)를 주조에 의하여 접합하여 제조하였다. 그러나 동은 피복된 고금층에 주조되는 연합금의 용융온도보다 융점이 낮으므로 주조할 때에 격자체(2)의 극판귀부(1)와의 계면(界面) 부근의 도금층이 용해하여 엷게된다든가 극단일 때 벗겨져서 동이 노출되는 문제가 있었다. 이와같은 동의 노출을 방지하기 위하여 동과 합금화 하기 쉬운 연-석계 합금이나 석을 도금한 후 다시 연을 도금하여 도금층을 2층 구조로도 하였지만 완전하게 도금층이 벗겨지는 것을 방지할 수가 없었다.In order to prevent this short circuit, the active material 3 attached to the side may be removed in a later step. However, in this case, the number of steps increases and the plating layer is damaged to expose copper. The conventional pole plate as described above was produced by applying copper expanded metal with a soft or soft-stone alloy and then joining the pole leaf portion 1 by casting. However, since copper has a lower melting point than the melting temperature of the alloy alloy cast on the coated high-gold layer, the plating layer near the interface with the pole return portion 1 of the lattice body 2 melts and becomes thinner at the time of casting. When peeled off, there was a problem that the copper is exposed. In order to prevent such exposure of copper, the plated layer was also double-layered by plating a lead-stone alloy or stone which is easily alloyed with copper and then plated with lead, but the plating layer could not be completely prevented from peeling off.
주조온도의 제어를 엄밀히 하여 될 수 있는대로 낮은 온도에서 주조하는 방법도 있으나, 이 방법으로는 극판귀부(1)의 성형이 불량하게 되여 격자체(2)와 극판귀부(1)와의 밀착성이 좋지 못하여 전기 저항이 증대한다는 문제가 있었다.Although casting can be performed at a low temperature as closely as possible by controlling the casting temperature, this method leads to poor molding of the pole tip 1 and thus good adhesion between the lattice 2 and the pole tip 1. There was a problem that the electrical resistance increases.
본 고안은 품질, 생산성이 우수한 연축전지용 극판을 제공하고 품질이 우수한 연축전지용 극판을 얻을 수 있는 연축전지용 극판을 제공하는 것을 목적으로 하며, 동 또는 동합금으로 된 엑스팬드메탈에 연 또는 연합금을 도금한 것을 집전용 격자체로서 사용한 연축전지용 극판에 있어서, 격자체의 측부에 보호체를 설치한 것을 특징으로 한 연축전지용 극판인 것이다.The object of the present invention is to provide a lead-acid battery plate with excellent quality and productivity, and to provide a lead-acid battery pole plate from which a lead-acid battery plate with high quality can be obtained, and to plate lead or alloy alloy in an expanded metal made of copper or copper alloy. In the lead-acid battery pole plate, which is used as a current collector lattice body, it is a lead-acid battery pole plate characterized by providing a protective member on the side of the lattice body.
먼저 본 고안의 연축전지용 극판의 실시예를 도면에 의하여 설명한다.First, an embodiment of a lead-acid battery plate of the present invention will be described with reference to the drawings.
부호(1)은 연합금으로된 집전용의 극판귀부, (2)는 격자체이며, 이것은 동 엑스팬드 메탈에 연이 도금된 것이다. (3)은 부극활물질(4)는 합성수지제의 하부연결체(5)는 연합금으로 된 보호체, (6)은 연합금 보호체(5)에 복수개 형성된 돌기이고, 보호체(5)는 격자체(2)의 측부 전면을 덮는 크기의 판상체이며, 폭(제2도의 L)은 격자체(2)의 두께이상의 크기로 되여있다.Reference numeral 1 denotes a pole receptacle for current collector made of alloy, and 2 denotes a lattice, which is plated with copper expanded metal. (3), the negative electrode active material (4) is a lower connector (5) made of synthetic resin, a protector made of alloy, (6) a plurality of protrusions formed on the alloy protector (5), and the protector (5) It is a plate-shaped body of the magnitude | size which covers the side part whole surface of the grating body 2, The width | variety (L of FIG. 2) is set to the magnitude | size more than the thickness of the grating body 2. As shown in FIG.
이와같은 극판은 예를들어 설명하면 다음과 같다.For example, such a plate is as follows.
먼저 동으로 된 판을 엑스팬드 기동하여 동 액스팬드메탈을 얻고 이것을 순차적으로 탈지, 산철, 세제, 건조하고 납을 도금하고 다시 연을 도금하여 격자체 (2)가 얻어진다. 그리고 격자체(2)의 상부에 극판귀부(1)를 주조에 의하여 접합하고 다음에 격자체(2)의 하부연결체(4)를 부착하며 다시 제3도에 표시한 바와같이 격자체(2)의 측부에 보호체(5)의 돌기(6)를 삽입시켜 보호체(5)는 돌기(6)를 사이에 두고 연-석계 합금의 연으로 격자체(2)에 접착한다.First, the plate made of copper is expanded to obtain copper expanded metal, which is sequentially degreased, ferrous iron, detergent, dried, and plated with lead and plated with lead again to obtain a lattice (2). Then, the pole pins 1 are joined to the upper part of the lattice 2 by casting, and then the lower connecting body 4 of the lattice 2 is attached, and as shown in FIG. 3 again, the lattice 2 By inserting the projection 6 of the protector 5 on the side of the c), the protector 5 is bonded to the lattice 2 with a soft-stone alloy with the protrusion 6 interposed therebetween.
동 엑스팬드메탈에 대한 연의 도금이나 극판귀부(1) 하부연결체(4) 보호체 (5)의 부착은 상기 순서에 한하지 않았고, 예를들어 동 엑스팬드메탈에 보호체(5)를 거접착한 후에 동 엑스팬드메탈에 연을 도금하고, 극판귀부(1), 보호체(5)를 부착한 후에 동 엑스팬드메탈에 연을 도금하고, 하부연결체(4)를 부착하도록 하여도 좋다.The plating of the lead on the copper expanded metal or the attachment of the pole connector (1), the lower connector (4) and the protector (5) were not limited to the above procedure, and for example, the protector (5) was hung on the copper expanded metal. After adhering, the lead metal may be plated on the copper expanded metal, and after the pole return portion 1 and the protector 5 are attached, the lead metal may be plated on the expanded metal and the lower connector 4 may be attached. .
다음에 통상의 방법으로 격자체(2)에 활물질(3)을 충진하고 화성(化成)하여 본 고안의 극판이 얻어진다.Next, the lattice 2 is filled with the active material 3 and chemically formed by a conventional method to obtain the electrode plate of the present invention.
이러한 구성의 연축전지용 극판으로서는 격자체(2) 측부에 격자체(2)의 두께 이상의 폭(제2도의 L)을 가진 보호체(5)가 설치되여 있으므로 특히 활물질(3)의 충진시에 격자체(2)의 연의 도금층이 손상되므로서 동이 노출되는 일은 없다.The lead plate for lead-acid batteries having such a configuration is provided at the side of the grating body 2 with a protective body 5 having a width (L in FIG. 2) or more than the thickness of the grating body 2, and thus particularly at the time of filling the active material 3. Since the lead plating layer of itself 2 is damaged, copper is not exposed.
또한 활물질(3)의 충진이 보호체(5)에 의하여 행하여지므로 격자체(2)는 활물질(3)로 피복되는 것으로 되여, 충·방전에 대하여 연의 도금층이 반응하는 것이 힘들게 되며, 전지사용중에 도금층이 파괴되는 것으로 인하여 동이 노출되는 일이 없고, 활물질(3)의 충진이 보호체(5)에 의하여 행하여지므로 충진의 작업성, 나아가서는 극판의 생산성이 크게 향상된다.In addition, since the filling of the active material 3 is performed by the protector 5, the lattice 2 is covered with the active material 3, which makes it difficult for the lead plating layer to react with charging and discharging. The copper layer is not exposed due to the destruction of the plating layer, and the filling of the active material 3 is performed by the protector 5, so that the workability of filling, and further, the productivity of the electrode plate is greatly improved.
또한 격자체(2)가 동으로 되여 있으므로 방전 전압 특성, 중량효율이 우수하며 극판귀부(1)는 연제도 좋고, 격자체(2)는 동합금제로도 좋으며, 하부연결체(4)는 연 또는 연합금제로도 좋고, 격자체(2)는 연합금을 도금한 것도 좋으며, 보호체 (5)는 격자체(2)의 중앙부 또는 일부에 설치하여도 좋다. 보호체(5)는 연 또는 합성수지제로도 좋으며 합성수지제의 보호체(5)는 열에 의한 접착이나 초음파, 핫멜트(hot-melt) 에폭수지등을 사용한 접착에 의하여 격자체(2)의 측부에 돌기(6)를 사이에 두고 부착하여도 좋고 제4도에 표시한 바와같이 사출성형에 의하여 격자체 (2)에 부착하여도 좋다.In addition, since the lattice 2 is made of copper, the discharge voltage characteristics and weight efficiency are excellent, the pole return portion 1 may be soft, the lattice 2 may be made of copper alloy, and the lower connecting member 4 may be soft or It may be made of alloying metal, the lattice 2 may be plated with alloying metal, and the protective member 5 may be provided at the center or part of the lattice 2. The protector 5 may be made of soft or synthetic resin, and the protector 5 made of synthetic resin protrudes on the side of the lattice 2 by adhesion by heat, ultrasonic bonding, or hot-melt epoxy resin. (6) may be attached to each other, or may be attached to the lattice 2 by injection molding as shown in FIG.
보호체(5)는 제5도에 표시한 바와같이 보호체(5)에 형성한 복수의 요부(5a)에 격자체(2)의 측부의 철부(2a)를 삽입하여 연이나 수지(7)등으로 접착하여 격자체(2)에 부착하도록 하여도 좋으며, 2매의 보호체를 초음파에 의하여 접착한다든가 페스트(Paste) 상의 연을 도포하고 가열하여 접착한다든가 부착하도 좋다.As shown in FIG. 5, the protector 5 inserts the convex part 2a of the side part of the lattice 2 into the some recessed part 5a formed in the protector 5, and has the lead or resin 7 It may be adhered to the lattice 2 by bonding to the lattice 2 or the like. Alternatively, the two protective bodies may be bonded by ultrasonic waves, or by applying a lead on a paste and heating to bond them.
이상과 같이 본 고안의 연축전지용 극판에 의하면 격자체(2)의 측부에 보호체(5)를 설치하였으므로 후공정에 있어서 격자체(2)의 측부의 도금층이 손상되는 것을 방지하 수 고, 따라서 동의 노출에 의한 자기방전의 증가, 용량저하, 충전효율의 악화 등을 방지할 수 있으며, 보호체(5)에 의하여 활물질(3)을 충진할 수 있으므로 전지 사용중에 있어서의 동의 노출을 방지할 수 있고, 충진의 작업성, 나아가서는 극판의 생산성을 향상시키며 특히 보호체(5)의 폭(제2도의 L)을 격자체(2)의 두께이상으로 하면 활물질(3)의 충진시에 격자체(2)의 도금층이 손상되는 것을 방지하여 동의 노출을 방지할 수 있고 보호체(5)는 합성수지제, 연제, 연합금제 어느 쪽이든 좋으므로 극판의 용도에 따라서 적절히 사용할 수 있다.As described above, according to the lead plate for lead-acid batteries of the present invention, since the protective member 5 is provided on the side of the grating body 2, the plating layer on the side of the grating body 2 can be prevented from being damaged in a later step. It is possible to prevent an increase in self discharge due to copper exposure, a decrease in capacity, a deterioration in charging efficiency, and the like, and the active material 3 can be filled by the protector 5 to prevent exposure of copper during battery use. The workability of filling, and also the productivity of the electrode plate, is improved, and in particular, when the width of the protective body 5 (L in FIG. 2) is greater than or equal to the thickness of the lattice 2, the lattice body is filled when the active material 3 is filled. Since the plating layer of (2) can be prevented from being damaged, exposure to copper can be prevented, and the protective member 5 can be any of a synthetic resin, a softener, and an alloyed metal, and can be appropriately used depending on the purpose of the electrode plate.
보호체(5)를 요부(5a)에 격자체(2) 측부의 각 철부(2a)를 삽입하거나 돌기 (6)를 격자체(2) 측부에 삽입시켜서 격자체(2)에 접착시키도록 하면 보호체(5)의 격자체(2)에의 접착을 견고히 할 수 있고, 접착작업도 용이하다.When the protective body 5 is inserted into the recessed part 5a, each convex part 2a of the side of the lattice 2 is inserted, or the projection 6 is inserted into the side of the lattice 2 so as to adhere to the lattice 2 The protective body 5 can be firmly adhered to the lattice 2, and the bonding operation is easy.
따라서 전기 저항의 증대를 방지할 수 있으며, 동엑스팬드메탈과 극판귀부 (1)과의 계면부근으로부터의 동의 용출을 방지할 수 있어 품질이 우수한 연축전지용 극판을 얻을 수 있다.Therefore, an increase in electrical resistance can be prevented, and copper elution can be prevented from near the interface between the copper expanded metal and the pole return portion 1, thereby obtaining a lead-acid battery plate having excellent quality.
