Abstract
A non-aqueous electrolyte secondary battery includes a positive electrode, a negative electrode, and a non-aqueous electrolyte. The positive electrode employs a positive electrode active material wherein oxide containing Al and/or hydroxide containing Al having a protruding-shape is uniformly distributed and adhered to the surface of a positive electrode active material particle.
