Abstract
An electrolyte injection method for injecting an electrolyte into a battery case tightly closed except an electrolyte injection hole, said method comprising an electrolyte injection nozzle airtightly mounted on the electrolyte injection hole, exhausting the space inside the battery case with the electrolyte injection nozzle mounted on the electrolyte injection hole, an electrolyte pot connected to the electrolyte injection nozzle via an electrolyte injection valve and for storing the electrolyte to be injected into the battery case, and feeding a given amount of the electrolyte into the electrolyte pot via an electrolyte feeding valve, and injecting the electrolyte in the electrolyte pot under pressure into the battery case, whereby the pressurized gas feeding means is connected to the electrolyte pot via a pressure valve, and the electrolyte is injected by pressurizing the electrolyte after exhausting internal space of the battery case.
