    • A non-aqueous secondary battery, such as a lithium ion secondary battery, eliminates local potential distribution in a cell due to the side reaction during charge/discharge, and does not undergo deterioration of capacitance, deterioration of a positive electrode material, and deposition of metallic lithium. The non-aqueous secondary battery has an electrode group and an electrolyte disposed in one container. The electrode group includes a positive electrode, a negative electrode, and a separator, and is divided into a plurality of electrode groups separated electrically. The electrode groups are in contact with an identical electrolyte, and terminals are led out from the positive electrode and the negative electrode to the outside of the container on every electrode group. Terminals are connected on every positive electrode and negative electrode at the outside of the container, and the terminals at the outside of the container are connectable and disconnectable easily.
    • 诸如锂离子二次电池的非水二次电池由于充放电期间的副反应而消除了电池中的局部电势分布,并且不会发生电容的劣化,正极材料的劣化和沉积 金属锂。 非水二次电池具有设置在一个容器中的电极组和电解质。 电极组包括正电极,负电极和隔膜,并且被分成电分离的多个电极组。 电极组与相同的电解质接触,端子从每个电极组的正极和负极引导到容器的外部。 端子连接在容器外侧的正极和负极上,容器外部的端子可以容易地连接和断开。
