Title:
POSITIVE ELECTRODE AND NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY INCLUDING THE SAME
Document Type and Number:
Japanese Patent JP2022141192
Kind Code:
A
Abstract:
To provide a positive electrode using spinel-type manganese-containing composite oxide that is capable of attaching excellent capacity degradation resistance to a nonaqueous electrolyte secondary battery on repeated charge-discharge cycles.SOLUTION: A positive electrode includes a positive electrode collector and a positive electrode active material layer supported by the positive electrode collector. The positive electrode active material layer includes a positive electrode active material. The positive electrode active material is a lithium complex oxide having a spinel-type crystal structure and containing Mn. The lithium composite oxide has a phosphonic acid compound coating having fluorinated hydrocarbon groups on the surface thereof. The ratio of the phosphonic acid compound to the lithium composite oxide is between 0.1 mass% and 1.0 mass% inclusive.SELECTED DRAWING: Figure 1
