SECONDARY BATTERY POSITIVE ELECTRODE, AND SECONDARY BATTERY

This secondary battery positive electrode is provided with a positive-electrode current collector, a positive-electrode mixture layer, and an intermediate layer disposed between the positive-electrode current collector and the positive-electrode mixture layer. The intermediate layer comprises: a first intermediate layer that includes a non-oxide conductive inorganic compound and a positive-electrode active material; and a second intermediate layer that includes an insulating inorganic material and a non-oxide conductive inorganic compound. The conductive inorganic compound becomes an insulating oxide at 300° C. or above.
