摘要： A secondary battery includes an electrode assembly, an open-topped can accommodating the electrode assembly, and a cap assembly sealing the can. The electrode assembly includes a positive electrode plate having a positive electrode coated portion and positive electrode non-coating portions, a negative electrode plate having a negative electrode coated portion and negative electrode non-coating portions, and a separator interposed between the positive and negative electrode plates and wound with the electrode plates. The positive electrode non-coating portion has a region where the height of the positive electrode non-coating potion is lower than that of the positive electrode coating portions.
摘要翻译：二次电池包括电极组件，容纳电极组件的敞开的顶盖，以及密封罐的盖组件。电极组件包括具有正极涂覆部分和正极非涂覆部分的正极板，具有负极涂覆部分和负极非涂覆部分的负极板以及介于正极和负极之间的隔板并用电极板缠绕。正极未涂布部分具有正极未涂覆部分的高度低于正极涂覆部分的高度的区域。
