Abstract
一种电极组件(50)及其制造方法和制造系统、电池单体(40)、电池(10)及用电装置。电极组件(50)包括:第一极片(51),包括多个折弯段(511)和多个层叠设置的第一层叠段(512),每个折弯段(511)用于连接两个相邻的第一层叠段(512),折弯段(511)具有引导部(514),引导部(514)用于在生产时引导折弯段(511)折弯;多个第二极片(52),第二极片(52)与第一极片(51)极性相反且包括第二层叠段(522),每个第二极片(52)的第二层叠段(522)设置于相邻两个第一层叠段(512)之间;隔离膜(53),用于将第一极片(51)和第二极片(52)隔开,隔离膜(53)包括多个隔离段(531),每个隔离段(531)设置于相邻的第一层叠段(512)和第二层叠段(522)之间。引导部(514)能够引导第一极片(51)在预定区域折弯,降低第一极片(51)和第二极片(52)偏离预定位置的风险,减少析锂。
