Positive electrode material and lithium secondary battery using the same

Abstract

A positive electrode material for a lithium secondary battery of the present disclosure includes a positive electrode active material, a barium titanate-based dielectric, and at least one of Compound I which contains the element Ba and has the largest peak at a position with 2θ=24° to 26° in an X-ray diffraction pattern obtained according to X-ray diffraction measurement using CuKα rays; and Compound II which contains the element Ti and has the largest peak at a position with 2θ=26° to 28° in an X-ray diffraction pattern obtained according to X-ray diffraction measurement using CuKα rays. At least one of Compounds I and II is disposed in contact with the dielectric.
