NOVELTY - The battery has positive and negative electrode current collecting plates (104,105) that are connected with an electrode winding group (102) through positive and negative electrode tab groups (405,406). The electrode winding group and the electrode current collecting plates are incorporated in battery can. The electrode tab groups are arranged at the identical direction side that goes to the flat surface where the electrode winding group opposes with respect to flat plates (204,205) of the electrode current collecting plates. The electrode tab groups are joined to each flat plate.    USE - Non-aqueous electrolytic battery such as flat shaped flat winding type lithium ion battery and square shaped flat winding type lithium ion battery used for vehicles such as motor vehicle, plug-in electric vehicle (PEV), and hybrid electric vehicle (HEV).    ADVANTAGE - Since the positive and negative electrode tab groups are arranged at the identical direction side that goes to the flat surface where the electrode winding group opposes with respect to flat plates of the positive and negative electrode current collecting plates, the collector and the electrode current collecting plates can be joined, without reversing the winding group, when joining the electrode tab groups to electrode current collecting plates through welding respectively. The collector and current collecting plates can be joined at the identical time, thus the productivity of the non-aqueous electrolytic battery can be improved. The output of the non-aqueous electrolytic battery is increased. The capacitance of the non-aqueous electrolytic battery is improved.
