BIPOLAR ELECTRODE PAIR/SEPARATION MEMBRANE ASSEMBLY, BIPOLAR BATTERY INCLUDING SAME, AND PRODUCTION METHOD THEREOF

摘要

The present invention relates to a bipolar electrode pair/separation membrane assembly comprising: a bipolar electrode pair-adhesive film assembly which includes a bipolar electrode pair for forming an electrode layer that contains active materials which may have different polarities in the central part of both upper and lower sides of a current collector plate, and an adhesive film formed on one side or upper and lower sides of four sides of an uncoated current collector plate that does not include the electrode layer in the bipolar electrode pair, relative to at least two or more sides; and a separation membrane which is laminated on one side or both upper and lower sides of the bipolar electrode pair-adhesive film assembly. Further, the invention provides a bipolar electrode pair/separation membrane assembly, a bipolar battery including the bipolar electrode pair/separation membrane assembly, and a production method thereof wherein the current collector plate and the separation membrane are directly bonded by the adhesive film, thereby sealing the bipolar electrode pair. According to the present invention, since the bipolar electrode pair and the separation membrane assembly are electrically connected according to the usage purpose, it is possible to provide the battery with desirable capacity and desirable voltages.
