Title:
TESTING METHOD, SECONDARY BATTERY LAMINATE PRODUCTION METHOD, AND SECONDARY BATTERY PRODUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2021/172143
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a novel technology capable of sufficiently suppressing bonding failure by identifying poorly coated areas with a high degree of accuracy when producing a secondary battery laminate in which battery members are bonded to one another using an adhesive material. The testing method of the present invention is used when forming a dried material on a bonding surface by performing a step for applying a coating material onto the bonding surface of an electrode/and or a separator, and a step for forming an adhesive material by drying the coating material on the bonding surface. This testing method involves identifying a poorly coated area by measuring the displacement of the bonding surface to which the coating material was applied by using a laser displacement meter before performing the step for forming the adhesive material.
