An object of the present invention is to provide a non-aqueous electrolyte secondary battery using a positive electrode material with improved conductivity. A general formula (1): LiFe1-xQxP1-yWyO4 (wherein Q is at least one selected from the group consisting of Zr, Sn and Y, and W is selected from Si and Al). A positive electrode material comprising lithium-containing composite oxide particles represented by at least one kind, x is 0≰x≰1, y is 0≰y≰1, and a conductive material made of carbon, a binder, The lithium-containing oxide particles have a particle diameter of 10 nm to 5 μm, and the above-mentioned problems are solved by a non-aqueous electrolyte secondary battery comprising: a positive electrode including: a negative electrode; an electrolyte; and a separator. To do. [Selection] Figure 1 |
