Abstract

一种电池(10)及其相关装置、制备方法和制备设备。该电池(10)包括多个电池单体(20),所述多个电池单体(20)中的至少一个电池单体(20)包括泄压机构(213),所述泄压机构(213)用于在所述至少一个电池单体(20)的内部压力达到阈值时致动以泄放所述内部压力;以及汇流部件(12),用于电连接所述多个电池单体(20);其中,所述泄压机构(213)与所述汇流部件(12)分别被布置在所述至少一个电池单体(20)的不同侧,以使得在所述泄压机构(213)致动时来自所述至少一个电池单体(20)的排放物沿远离所述汇流部件(12)的方向排放。通过泄压机构(213)和汇流部件(12)的这种布置方式,使得电池(10)的安全性能得到显著提高。
