POSITIVE ELECTRODE ACTIVE MATERIAL FOR NONAQUEOUS ELECTROLYTE SECONDARY BATTERY, METHOD FOR MANUFACTURING SAME, AND POSITIVE ELECTRODE FOR NONAQUEOUS ELECTROLYTE SECONDARY BATTERY, AND NONAQUEOUS ELECTROLYTE SECONDARY BATTERY

摘要

PROBLEM TO BE SOLVED: To improve a charge-discharge cycle characteristic at high voltage, and charge/discharge efficiency after storage at high temperatures in a nonaqueous electrolyte secondary battery, by improving a positive electrode active material used for the nonaqueous electrolyte secondary battery. SOLUTION: This nonaqueous electrolyte secondary battery includes a positive electrode 1, a negative electrode 2, and a nonaqueous electrolyte. The positive electrode employs a positive electrode active material for a nonaqueous electrolyte secondary battery wherein oxide containing Al and/or hydroxide containing Al having a protruding-shape is uniformly dispersed and adhered to the surface of each positive electrode active material particle.
