Battery monomer and battery pack

电池单体及电池组

Abstract

The invention relates to a battery monomer. The battery monomer comprises a package structure body, a battery cell and an electrode lug, wherein the package structure body covers outside the battery cell and is used for packaging the battery cell directly, the electrode lug is connected with the battery cell and is partially exposed to the outside of the package structure body, the package structure body comprises an upper shell and a lower shell, the upper shell and the lower shell are combined mutually to form a closed space for containing the battery cell, the upper shell is made of a flexible material, the lower shell is made of a rigid material, and a battery core is formed by an anode plate, a diaphragm and a cathode plate through stacking. The invention also relates to a battery pack. The battery pack comprises a plurality of battery monomers, wherein the plurality of battery monomers are stacked with one another.
本发明涉及一种电池单体,包括封装结构体、电芯及极耳,所述封装结构体罩于所述电芯外部,直接封装所述电芯,所述极耳与所述电芯连接,并部分暴露于所述封装结构体外部,所述封装结构体包括上壳体与下壳体,所述上壳体及所述下壳体相互结合形成一密闭空间用于容纳所述电芯,所述上壳体的材料为软性材料,所述下壳体的材料为刚性材料,所述电芯由正极极片、隔膜、负极极片层叠组成。本发明还涉及一种电池组,包括多个电池单体,所述多个电池单体相互叠加设置。
