A non-aqueous electrolyte secondary battery having high capacity and high output is obtained. A positive electrode mixture includes a first positive electrode active material having a large Ni content and a large average particle size, a second positive electrode active material having a small Ni content and a small average particle size, and an average particle size. A nonaqueous electrolyte secondary battery having first and second conductive assistants different from each other. [Selection] Figure 8 |
