Abstract
A non-aqueous electrolyte secondary battery has a positive electrode (11) containing a positive electrode active material capable of intercalating and deintercalating lithium ions; a negative electrode (12); and a non-aqueous electrolyte (14). The positive electrode active material contains LibFePO4, where 0≦b<1, and a lithium-containing metal oxide represented by the general formula LixNiyMnzMaO2, where M is at least one element selected from the group consisting of Na, K, B, F, Mg, Al, Ti, Co, Cr, V, Fe, Cu, Zn, Nb, Mo, Zr, Sn, and W, and where x, y, z, and a satisfy the following conditions 1<x<1.3, 0<y≦1, 0<z≦1, y<z, and 0≦a.
Claims4
