POSITIVE ELECTRODE FOR NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY AND NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY

摘要

A positive electrode (10) used in a non-aqueous electrolyte secondary battery comprises a positive electrode collector (20) and a positive electrode active substance layer (22) formed upon the positive electrode collector (20). The positive electrode active substance layer (22) has a positive electrode active substance (24) and an aromatic organophosphate compound (30). The aromatic organophosphate compound (30) ideally has a solubility of no more than 1% relative to a non-aqueous electrolytic solution being a liquid non-aqueous electrolyte.
