MANUFACTURE METHOD OF POCKET TYPE NI-ZN BATTERY

摘要

Provided in the present invention is a manufacturing method of a nickel-zinc pocket-type battery, capable of preventing the separation of a negative electrode active material from the inside of a strip, and extending the lifespan by coating a separation membrane of a negative electrode and a positive electrode with a polymer solution and preventing the leakage of active material powder. The method comprises the steps of: (a) manufacturing two sheets of surface-perforated Ni strip as a pocket shape formed with an insertion hole; (b) evenly charging the active material to the inside of the insertion hole; (c) contacting two sheets of metal plate to a capsulated negative electrode or positive electrode active material by applying external force to the metal plate; (d) manufacturing one electrode plate by inserting the needed amount of the strip in between a rug and a side bead, and coupling the same; (e) group-assembling the completed electrode plate, and connecting a pole rod to an external terminal; and (f) filling the group-assembled electrode plate with an electrolyte inside a case.
