Title:
POSITIVE ELECTRODE FOR SECONDARY BATTERY, PRODUCTION METHOD THEREFOR, AND SECONDARY BATTERY
Document Type and Number:
WIPO Patent Application WO/2024/070147
Kind Code:
A1
Abstract:
A positive electrode 13 for secondary batteries according to the present disclosure comprises a positive-electrode current collector 11 and a positive-electrode active material layer 12 fixed to the positive-electrode current collector 11, wherein the positive-electrode active material layer 12 comprises a positive-electrode active material and poly(vinyl alcohol) modified with a phosphorus compound. This method for producing the positive electrode 13 for secondary batteries comprises preparing a polymer solution comprising poly(vinyl alcohol), a phosphorus compound, and a solvent, preparing a positive-electrode slurry comprising the polymer solution and a positive-electrode active material, and applying the positive-electrode slurry to a positive-electrode current collector 11 to form a positive-electrode active material layer.
