(EN) The invention provides a battery comprising an external encapsulation layer and an inner electrode assembly, wherein the external encapsulation layer comprises one or two electrically conductive planes; the internal electrode assembly comprises a battery inner positive electrode, a negative electrode and a diaphragm; the electrically conductive plane of the external encapsulation layer is connected to the positive or negative electrode of the internal electrode assembly. There is also provided a battery pack composed of two or more batteries having electrically conductive planes. The two or more batteries are electrically connected through the electrically conductive planes of the respective batteries. Since the adjacent batteries in the battery pack are connected through the electricallyconductive planes, unnecessary electrical connectors or structural members are removed, so that the volume fraction of the inactive materials in the entire battery pack can be reduced, and the energydensity of the battery pack can be improved.
(ZH) 本发明提供了一种电池，所述电池包括外部封装层和内部电极组合体，所述外部封装层包括一个或者两个导电平面，所述内部电极组合体包括电池内部正极、负极和隔膜，所述外部封装层的所述导电平面与所述内部电极组合体的正极或者负极相连接。还提供一种由两个或两个以上具有导电平面的电池构成的电池组，所述两个或两个以上电池的通过所述电池各自的导电平面电连接。由于电池组中相邻的电池通过导电平面相连，省去了多余的电连接件或者结构件，因此可以降低整个电池组中非活性材料的体积占比，提高电池组的能量密度。
