POSITIVE ELECTRODE FOR SECONDARY BATTERY AND SECONDARY BATTERY

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. The positive electrode mixture layer contains a first positive electrode active material having a compressive strength of 400 MPa or more, and a second positive electrode active material having a compressive strength of 250 MPa or less. When the positive electrode mixture layer is divided 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.
