POSITIVE ELECTRODE FOR NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY, NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY, BATTERY MODULE, AND BATTERY SYSTEM USING SAME, AND METHOD FOR MANUFACTURING POSITIVE ELECTRODE FOR NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY
Document Type and Number:
WIPO Patent Application WO/2023/249066
Kind Code:
A1
Abstract:
This positive electrode (1) for a non-aqueous electrolyte secondary battery has a positive electrode current collector (11) including a positive electrode current collector main body (14) composed of a metal material, and a positive electrode active material layer (12) present on the positive electrode current collector (11), wherein: the positive electrode active material layer (12) contains a positive electrode active material and a conductive auxiliary agent, or the positive electrode active material layer (12) contains a positive electrode active material but does not contain a conductive auxiliary agent; one or both of the positive electrode current collector (11) and the positive electrode active material layer (12) contain conductive carbon; the conductive carbon includes amorphous carbon; and the content of the conductive carbon with respect to the mass of remaining parts excluding the positive electrode current collector main body (14) is 0.5-3.5 mass%.
