Abstract:
A positive electrode for a non-aqueous electrolyte secondary battery contains a first particle and a second particle. The first particle contains an electrochemically active positive-electrode active material, and the positive-electrode active material contains a lithium transition metal oxide. The second particle contains an electrochemically inactive metal oxide. An electrochemically inactive phosphate adheres to the surface of the second particle.
