Positive electrode for secondary battery, and secondary battery

Abstract

A positive electrode for a secondary battery including a positive electrode current collector, and a positive electrode mixture layer containing a positive electrode active material and disposed on a surface of the positive electrode current collector in which the positive electrode mixture layer contains a first positive electrode active material having a compressive strength of 400 MPa or less, a second positive electrode active material having a compressive strength smaller than the compressive strength of the first positive electrode active material, and when the positive electrode mixture layer is zoned into a first region and a second region having the same thickness, the first positive electrode active material is contained more in the first region than in the second region, and the second positive electrode active material is contained more in the second region than in the first region is used.
