    摘要: Provided is a method of manufacturing an electrode assembly which is different from a stack folding method and a stack method. The method includes forming a unit structure, which comprises a stacked structure formed by sequentially stacking a first electrode, a first separator, a second electrode, and a second separator, or a structure formed by repeatedly forming the stacked structure a plurality of times (operation S10), forming the electrode assembly by repeatedly stacking the unit structure into a plurality of layers (operation S20), and discharging gas interposed between the layers by pressing the electrode assembly (operation S30).

    摘要: An electrical insulator and its related battery are disclosed in the present invention. The electrical insulator includes a separation region and a supporting region. The supporting region is disposed and covers the peripheral surface and at least a part of the lateral surface of the separation region. The battery includes the electrical insulator mentioned above. The electrical insulator is disposed between active material layers and contacts with the active material layers directly. The cathode and the anode active material layers are completely electrical isolated because the electrical insulator totally covers at least one active material layer orthographically. Hence, the inner short of the battery may be prevented.
