Title:
NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY POSITIVE ELECTRODE AND NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY
Document Type and Number:
WIPO Patent Application WO/2022/118737
Kind Code:
A1
Abstract:
A non-aqueous electrolyte secondary battery positive electrode (11) that is characterized by comprising a positive electrode collector (40) and a positive electrode mixture layer (42) that is provided on the positive electrode collector (40) and includes a positive electrode active material and a conductive material that includes carbon nanotubes. The non-aqueous electrolyte secondary battery positive electrode (11) is also characterized in that, when the positive electrode mixture layer (42) is bisected in the thickness direction, the mass ratio of carbon nanotubes to positive electrode active material in an upper-half region (42b) that is on a top surface side is smaller than the mass ratio of carbon nanotubes to positive electrode active material in a lower-half region (42a) that is on the positive electrode collector (40) side.
