METHOD FOR MANUFACTURING SEALED BATTERY

摘要

A method for manufacturing a sealed battery includes: injecting an electrolytic solution into an exterior; introducing a detection gas into the exterior; and detecting a leakage by detecting a leakage of the detection gas introduced into the exterior, the electrolytic solution in an electrolytic solution tank is pressure fed into the exterior by pressurizing the electrolytic solution tank by feeding a gas of a kind the same as the detection gas in the electrolytic solution tank where the electrolytic solution is stored, in order to inject the electrolytic solution into the battery container.
