Abstract
(EN)
This positive electrode for a non-aqueous electrolyte secondary battery comprises a positive electrode mixture layer. The positive electrode mixture layer comprises a positive electrode active material, a first binder, and a second binder. The positive electrode active material comprises a complex oxide represented by LiaNixCoyMe(1-x-y)O2 (where 0.97≤a≤1.2, 0.5≤x≤1, and 0≤y≤0.1, and the element Me includes at least one selected from the group consisting of Al, Mn, B, W, Sr, Mg, Mo, Nb, Ti, Si, and Zr). The first binder is a polymer binder that contains at least a vinylidene fluoride unit. The second binder is a polymer binder that contains at least a diene unit. The content of the second binder in the total amount of the first binder and the second binder is 5 to 35 mass%.
