A positive electrode and a non-aqueous electrolyte secondary battery using the non-aqueous electrolyte secondary battery

Even with positive electrode active material air exposure, and to provide an initial charge capacity positive electrode for suppressing a non-aqueous electrolyte secondary battery of the reduction of. A non-aqueous electrolyte secondary battery positive electrode including a lithium transition metal oxide, a lithium transition metal oxide, and tungsten oxide, made by mixing a carbonate compound, at least a portion of the surface of the lithium transition metal oxide to have a tungsten oxide, a portion of the surface of the tungsten oxide, characterized in that it is a positive electrode for a nonaqueous electrolyte secondary battery having a mixed carbonate compound.
