Description
技术领域
本发明涉及电池制备领域，具体涉及锂离子电池制造领域。
背景技术
锂离子电池是近几年发展起来的一种新型储能电池，并以其循环寿命好、环境友好、价格低廉等优点而受到人们的关注，并应用于电动汽车、储能领域及其数码电子等方向，但是目前市场上所用的锂离子电池大多属于小容量电池(≤20Ah),其在进行大倍率充放电过程中散热性能较小，对电池影响不明显，而对于大容量锂离子电池(≥20Ah)，由于进行大倍率(≥10C)以上的充放电会产生较大的热量，并储存于电池内部较难散热出去，严重影响电池的内部热量分布，并对极片材料结构、电解液造成严重影响，并影响到锂离子电池的循环性能及其倍率性能，由于热量得不到及时散热出去，会造成锂离子电池性能的严重恶化，降低锂离子电池的使用寿命。
发明内容
本发明公开了一种散热型锂离子电池，不但解决了目前大容量锂离子电池散热性能差等缺陷，提供了具有散热性能好，循环寿命长及组成模块简单的锂离子电池。
本发明包括有：外壳1和内壳2，所述的外壳1呈椭圆柱状，外壳1设有与内壳2外形大小匹配的内腔，所述的内壳2呈椭圆柱状，外壳1与内壳2之间设有电芯3，电芯3的顶部或底部设有正负电极4和安全阀5，所述的电芯3包括有正极片、隔离膜、负极片组成，由多块正极片、隔离膜、负极片采用卷绕方式排列，隔离膜位于相邻的正极片、负极片之间，把正极片、负极片隔开，外壳1的左右两端设有连接柱6，所述的外壳1表层和内壳2里层各覆盖有散热材料。
其特征在于,所述的散热材料采用以下材料配比而成:
云母5～15％、硅胶40～46.4％、镍6～8％、锰2～4％、氧化铜3～5％、汞1～2％、石墨8～16％、四氯化碳2～3％、钠1～6％、钛2～4％、聚丙烯酸酯类三元共聚物乳胶8～12％。
有益效果
采用椭圆型电池结构设计，并呈现椭圆环形结构，其电池在大倍率条件下产生的热量可以通过内环和外壳1的散热材料及时排向外部，提高其散热性能；并且外壳1表层和内壳2里层各覆盖有散热材料，不但散热性能优越，而且循环寿命长及简化了锂离子电池组成模块。
锂离子电池的正负极极柱位于电池短上下两端，可以提高其电池的快速散热性能，而位于左右两端的连接柱6则有利于锂离子电池组成模块，提高其电池利用率并提供其锂离子电池的能量密度，解决了目前大容量锂离子电池散热性能差等缺陷。
