ELECTRODE FOR NONAQUEOUS ELECTROLYTE SECONDARY BATTERY, NONAQUEOUS ELECTROLYTE SECONDARY BATTERY, AND MANUFACTURING METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide an electrode for a nonaqueous electrolyte secondary battery having excellent load characteristics and charge-discharge cycle characteristics, and to provide a nonaqueous electrolyte secondary battery using the same and a manufacturing method therefor.SOLUTION: The electrode for a nonaqueous electrolyte secondary battery includes a mixture layer containing an active material, and a porous insulation layer. The insulation layer is formed on the mixture layer and contains a resin having a cross-linked structure, and inorganic particles. Surface roughness Ra of the insulation layer is 0.2-0.4 μm, and a mixture layer containing the component of the insulation layer and the component of the mixture layer is formed on the boundary surface of the insulation layer and the mixture layer. A nonaqueous electrolyte secondary battery using the electrode for a nonaqueous electrolyte secondary battery, and a manufacturing method of a nonaqueous electrolyte secondary battery are also provided.
