WIPO Patent Application WO/2022/225380
Kind Code:
A1
Abstract:
The invention of the present application relates to a secondary battery manufacturing method in which a battery activation step includes a step of first charging 10% or less of an SOC, and a high temperature aging step. The battery manufacturing method according to the present invention allows a gas, generated after first charging, to be removed through the high temperature aging step performed thereafter, and thus provides the effects of improving the charging uniformity of an electrode in a subsequent charging step and increasing the available capacity of the battery.
