Description

극한 숄더하이트 용량 증가식 리튬 배터리 커버 플레이트{Capacity-increasing lithium battery cover plate with extreme shoulder height}Capacity-increasing lithium battery cover plate with extreme shoulder height}

본 발명은 리튬 배터리 부품에 관한 것으로, 특히 리튬 배터리의 커버 플레이트에 관한 것이다.The present invention relates to a lithium battery component, and more particularly to a cover plate of a lithium battery.

고용량 리튬 배터리의 하우징 공간은 최대한 효과적으로 이용되어야 한다. 상응한 부품의 커버 플레이트는 전극 압판, 밀봉 개스킷, 절연링 등 전극 부품을 설계한 후 커버 플레이트 위에 조립하여 하부의 하우징 공간을 적게 차지하도록 할 수 있다. 하지만 이런 방식으로 배치된 전극 압판의 표면은 커버 플레이트 주체의 상부 표면보다 현저하게 높다. 많은 리튬 배터리는 어깨 높이에 대해 명확한 제한이 존재하거나, 또는 리튬 배터리의 하우징 밑부분에서 전극 압판 표면까지의 전체 높이에 규격 제한이 존재하는데 전극 부품이 완전히 커버 플레이트 상부에 위치할 경우 오히려 배터리 하우징 높이가 더 한층 증가되는 것을 방해하게 되고, 배터리 하우징의 유효 이용공간의 더 충분한 개발에 불리하게 된다.The housing space of a high-capacity lithium battery must be used as efficiently as possible. The cover plate of the corresponding part can be assembled on the cover plate after designing electrode parts such as an electrode platen, a sealing gasket, and an insulating ring so as to occupy less space in the lower housing. However, the surface of the electrode platen arranged in this way is significantly higher than the upper surface of the cover plate main body. Many lithium batteries have a clear limitation on shoulder height, or there is a specification limit on the total height from the bottom of the lithium battery housing to the surface of the electrode platen. is prevented from further increasing, and is disadvantageous to a more sufficient development of the usable space of the battery housing.

종래기술의 미흡에 대하여 본 발명은 구조가 합리하고, 배터리 하우징 높이를 증가할 수 있는 극한 숄더하이트(shoulder height) 용량 증가식 리튬 배터리 커버 플레이트를 제공한다.In response to the shortcomings of the prior art, the present invention provides an extreme shoulder height capacity increasing lithium battery cover plate, which has a reasonable structure and can increase the height of the battery housing.

The two electrode connectors located at the bottom of the pad electrically contact the two electrode platens through corresponding electrode through-holes, and a bottom edge portion that is recessed and bent inward is installed at the bottom of each electrode through-hole, and the height of the bottom edge portion is installed. is lower than the bottom position of the cover plate main body, forming an electrode platen recessed mounting space.

나아가, 전극 관통홀은 상부 플랜지를 구비하고, 각자의 전극 관통홀에 놓인 전극 압판은 모두 밀봉 개스킷이 깔려 있으며, 전극 압판의 외주에는 각각 절연링이 씌워져 있고, 전극 관통홀의 상부 플랜지는 안쪽으로 구부러져 절연링을 눌러 접촉하여 전극 밀봉 구조를 형성한다.Furthermore, the electrode through-holes have upper flanges, the electrode platens placed in the respective electrode through-holes are all covered with sealing gaskets, the outer circumference of the electrode platens is covered with an insulating ring, and the upper flanges of the electrode through-holes are bent inward. The insulating ring is pressed and brought into contact to form an electrode sealing structure.

더 나아가, 밀봉 개스킷과 접촉하여 밀봉되는 곳의 전극 압판의 하단면 및 전극 관통홀의 보텀 엣지부의 표면에는 물결무늬의 홈이 형성되어 있어 밀봉 강화 구조를 형성한다.Furthermore, wave-patterned grooves are formed on the bottom surface of the electrode platen and the surface of the bottom edge of the electrode penetration hole where it is sealed by contacting with the sealing gasket to form a sealing reinforcement structure.

본 발명은 구조가 합리하고, 전극 관통홀 하단의 침강된 설계를 이용하여 전극 압판의 두께를 얇게 하지 않는 전제 하에 전극 압판의 침강된 설치를 실현할 수 있는 바, 즉 전극 압판 표면과 커버 플레이트 주체 상부 표면의 높이 차이를 줄이거나 동일하게 유지함으로써, 배터리 전체 높이가 결정된 경우 배터리 하우징의 높이를 더 증가하여 배터리의 유효 공간 용량을 증가할 수 있다.The present invention has a reasonable structure and can realize the submerged installation of the electrode platen under the premise that the thickness of the electrode platen is not thinned by using the submerged design of the bottom of the electrode through-hole, that is, the surface of the electrode platen and the upper part of the main body of the cover plate. By reducing or maintaining the same height difference between the surfaces, the effective space capacity of the battery may be increased by further increasing the height of the battery housing when the overall height of the battery is determined.
