▎ 摘　　要

NOVELTY - Battery comprises a cathode selected from a nickel-rich material and an iron phosphate material, and an ionic-electronic conducting polymeric coating on the cathode. USE - The battery such as lithium-ion battery, used for transportation applications such as longer-range electric vehicles, electric trucks, and electric aircrafts. ADVANTAGE - The battery includes an ionic-electronic conducting polymeric coating to address poor surface stability and degradation of nickel-rich cathode materials, and poor interfacial impedance and lower energy density with a coating which allows decreasing of non-active materials and increasing cathode active materials loading while improving battery performances. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method of forming a cathode, comprising providing a cathode powder, applying an ionic-electronic conducting polymeric coating on the cathode powder, and assembling the cathode powder into a cathode electrode.
