▎ 摘　　要

NOVELTY - A cathode active material comprises a layered cathode active material particles comprising at least one element chosen from nickel, cobalt and manganese, and graphene for coating the surface of the cathode material particles. USE - Active material used for cathode for electrode for lithium secondary battery (all claimed) used as portable power supplies for small device. Uses include but are not limited to portable communication device, notebook computer, camera, automobile, renewable energy, and smart grids. ADVANTAGE - The cathode active material is environmentally-friendly and economical, and can maximize the energy density per volume by reducing the use of conductive agents and densifying the electrodes, improves the electrode density of the layered positive electrode material containing nickel, reduces the process time, and improves the uniformity of electrode quality by removing or using a small amount of carbon black, which is difficult to disperse when mixing electrode materials. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: manufacture of the cathode active material; and an electrode.
