Abstract

本申请提供了一种电池，包括壳体和设置于所述壳体内的电极组件，所述电极组件包括第一极片、第二极片和隔离膜，所述隔离膜设置于所述第一极片和所述第二极片之间，所述电极组件由所述第一极片、隔离膜和第二极片卷绕形成。所述壳体包括第一壁，所述第一壁包括第一导电区域和与所述第一导电区域连接的第一非导电区域。所述电极组件还包括第一导电件，所述第一导电件电连接所述第一极片和第一导电区域，使得壳体只有导电区域具有极性，其他区域不具有极性，从而取消在电池外部包裹绝缘胶的工艺过程，降低工艺成本，减少能量密度损失。另外由于设置第一导电区域，对于第一极性，不需要设置极柱导出极性。本申请还提供一种具有上述电池的电子装置。
