Abstract

An electrode assembly and a secondary battery having the same improve efficiency and stability of the secondary battery. The electrode assembly includes: a positive electrode plate having a positive electrode collector on which a positive electrode coating portion and a positive electrode non-coating portion are formed; a negative electrode plate having a negative electrode collector on which a negative electrode coating portion and a negative electrode non-coating portion are formed; a separator disposed between the positive electrode plate and the negative electrode plate; and an insulating member disposed on one side of the positive or negative electrode non-coating portion, and formed adjacent to at least one of the ends of the positive electrode coating portion and/or at least one of the end of the negative electrode coating portion..
本发明提供了一种电极组件以及具有该电极组件的二次电池。更具体地,本发明提供了一种能够提高电池的效率和稳定性的电极组件以及具有该组件的二次电池。所述电极组件包括:正电极板,其具有正电极集电体以及形成在该正电极集电体上的正电极涂覆部分和正电极非涂覆部分;负电极板,其具有负电极集电体以及形成在该负电极集电体上的负电极涂覆部分和负电极非涂覆部分;隔板,其插置在所述正电极板与所述负电极板之间;绝缘部件,其设置在所述正电极非涂覆部分或所述负电极非涂覆部分的一侧,且形成为与所述正电极涂覆部分或所述负电极涂覆部分的两端中的一端相邻。
