A positive electrode for a non-aqueous electrolyte secondary battery, comprising:
- a positive electrode current collector;
- and a positive electrode active material layer formed on a surface of the positive electrode current collector, the positive electrode active material layer comprising a positive electrode active material, a binder agent, and a compound represented by the following general formula (1):
- where n is an integer from 1 to 4 and M is a metallic element.
A method of manufacturing a positive electrode for a non-aqueous electrolyte secondary battery, comprising the steps of:
- kneading, in a solvent, a mixture containing a positive electrode active material, a binder agent, a compound represented by the following general formula (1):
- where n is an integer from 1 to 4 and M is a metallic element, to prepare a positive electrode active material slurry;
- and
- coating the positive electrode active material slurry onto a surface of a positive electrode current collector to form a positive electrode active material layer on the surface of the positive electrode current collector.
