Abstract

A method for producing a battery, the method includes a liquid injecting process. In this liquid injecting process includes: a first liquid-injecting step of injecting an electrolytic solution of a first injection amount (V) determined so that a liquid-level height of the electrolytic solution falls within an intermediate liquid-level range in which the liquid-level height is equal to or higher than a first reference height but is lower than a second reference height while an air pressure in a metal battery case is regulated to a first air pressure; and a second liquid-injecting step of injecting the electrolytic solution in a remaining second injection amount up to a specified amount while increasing the air pressure in the metal battery case to a second air pressure higher than the first air pressure and maintaining the liquid-level height of the electrolytic solution within the intermediate liquid-level range.
