Abstract
A nonaqueous electrolyte secondary battery () in an example embodiment includes a positive electrode () having a lithium metal composite oxide, and a negative electrode () having graphite. The lithium metal composite oxide includes first composite oxide particles which are secondary particles formed by aggregation of primary particles having an average particle size of 50 nm to 5 μm, and second composite oxide particles which are non-aggregated particles having an average particle size of 2 μm to 20 μm. The positive electrode () has lower initial charge/discharge efficiency than the initial charge/discharge efficiency of the negative electrode ().
