POSITIVE ELECTRODE ACTIVE MATERIAL, POSITIVE ELECTRODE, AND NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY

摘要

Provided are: a positive electrode active material which can improve the input properties of a battery; a positive electrode comprising the positive electrode active material; and a non-aqueous electrolyte secondary battery equipped with the positive electrode. A battery element (10) for a non-aqueous electrolyte secondary battery comprises a positive electrode (11) comprising a positive electrode active material and a negative electrode (12) comprising a negative electrode active material. The positive electrode active material comprises a lithium-containing phosphoric acid compound having an olivine-type structure and lithium manganese having a spinel-type structure.
