Abstract
一种电芯结构(100)及其电池(200),该电芯结构(100)包括电芯本体(110)、电连接于所述电芯本体(110)的第一正极耳(120)及第一负极耳(130),第一正极耳(120)与第一负极耳(130)分别位于电芯本体(110)的不同侧;所述电芯结构(100)还包括电连接于电芯本体(110)的第二正极耳(140)或第二负极耳(170),第一正极耳(120)与第二负极耳(170)设置于电芯本体(110)的同一侧,以对电池保护板(101)供电;或第一负极耳(130)与第二正极耳(140)设置于电芯本体(110)的同一侧,以对电池保护板(101)供电。该电芯结构(100)通过在电芯本体(110)两侧均有极耳输出,可满足过大电流的需求,同时电芯本体(110)两侧的极耳可以使得电芯结构(100)充放电回路更顺畅,且由于过大电流的极耳位于电芯结构(100)的不同侧,可实现发热源分散,降低发热温升。
