Abstract
A material suitable for use in an electrode, preferably an anode, and processes of its formation are provided. The material includes an electrode base material and an organic artificial solid electrolyte interface material including a water soluble organic polymer coating the electrode base material. The polymer is polymerized with a crosslinker to form the organic artificial solid electrolyte interface material. The resulting artificial SEI coated electrode material demonstrates superior discharge rate capacity and cycle stability.
