Method for producing battery and battery

Abstract

A main object of the present disclosure is to provide a method for producing a battery in which the degrade of sealability in a liquid injection frame is inhibited. The present disclosure achieves the object by providing the method including: a preparing step of preparing an electrode member that includes an electrode layered body including a plurality of electrode layered in a z axis direction, and a liquid injection frame made of a resin arranged in a side surface of the electrode layered body; a liquid injection step of injecting a liquid electrolyte into the electrode layered body in the electrode member via the liquid injection frame; a temporary sealing step of temporary sealing the liquid injection frame by arranging a gas pack to cover an entire outer periphery of the liquid injection frame when viewed from an x axis direction orthogonal to the z axis direction; a gas storing step of storing a gas generated due to charging or aging in a space inside the gas pack; a degassing step of degassing the gas by opening the gas pack after the gas storing step; and a sealing step of sealing the liquid injection frame with a sealing member.
