,具体涉及一种蓄电池。
技术介绍
铅酸蓄电池因成本低廉、性能稳定并不断提高、绝大多数铅可以回收再利用等优势,一直是使用比较广泛的二次电源。极板是蓄电池的心脏,极板通过发生电化学反应将化学能转化成电能。极板极耳和汇流排汇集极板产生的电流,传输给外界。请参阅图1所示,图1为传统蓄电池正、负极耳结构示意图,正极耳1融入汇流排的极板厚度比负极耳2融入汇流排的极板厚度厚,导致正极耳1与汇流排的融合需要的热量多,铸焊时很容易出现正极耳1极板和汇流排融合良好,负极耳2极板已融断;负极耳2 极板和汇流排融合良好,正极耳1极板和汇流排融合有裂纹、气孔等缺陷,铸焊质量得不到保证,正、负极耳和汇流排的融合不良导致电池发热,甚至引起电池热失控,存在一定的质量隐患。
技术实现思路
本技术要解决的主要技术问题是提供一种蓄电池,通过对蓄电池正、负极耳的改进,提高了蓄电池的铸焊质量。为解决上述技术问题,本技术提供一种蓄电池,包括正极耳和负极耳,所述正、负极耳分别包括极耳头和极耳躯干,其特征在于,所述正极耳的极耳躯干融入汇流排的厚度和负极耳的极耳躯干融入汇流排的厚度相等。所述正极 ...
