Abstract
This non-aqueous electrolyte secondary battery, which is one example of an embodiment, comprises: a positive electrode that has a positive electrode mixture layer; a negative electrode; and a non-aqueous electrolyte. The positive electrode mixture layer contains a first lithium-and-transition-metal composite oxide represented by general formula LiNiCoMO(in the formula, 0.8≤x≤1.2, 0≤y≤0.2, 0<z≤0.5, and M is at least one metal element excluding Li, Ni, and Co), and a second lithium-and-transition-metal composite oxide represented by general formula LiNiMeO(in the formula, 0<a≤0.5, 0≤b≤0.5, and Me is at least one metal element excluding Li and Ni). The non-aqueous electrolyte contains a sulfonyl imide salt.
