ELECTROLYTE INJECTION APPARATUS OF RESERVED BATTERY

摘要

PURPOSE: An electrolyte injection apparatus of reserved battery is provided to simplify the structure and reduce manufacturing cost by assembling a subside piston to a main piston. CONSTITUTION: The apparatus comprises a main piston(5) formed at upper part of an electrolytic bath(2); a subside piston(7) assembled to the main piston and operating by gas pressure of a gas generator(6); a subside piston housing(8) for operating the subside piston; and a cutting pin(9) of long rod shaped structure having a blade(9A) at end portion of the cutting pin(9) and formed monolithic lining with the subside piston(7). The spacing size of the subside piston housing(8) has 2-3 times of the operating space.
