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。
