Abstract
An object of the present invention is to provide a lithium secondary battery cathode which can more improve characteristics of the battery. The cathode of the present invention includes an electroconductive cathode current collector, a plurality of plate-like particle formed of a cathode active material, and a binder containing microparticles formed of the cathode active material and being smaller than the plate-like particles. The plate-like particles are formed so as to have an aspect ratio of 4 to 50. The plate-like particles are arranged such that the particles cover the surface of the cathode current collector surface at a percent area of 85 to 98%. The binder is disposed so as to intervene between two adjacent plate-like particles.
