Abstract

An armored graphene cathode is developed for high rate and long-life lithium ion supercapacitors by the preliminary electrochemical coating. The obtained full-cell delivers a high energy density of 160 Wh kg−1 and a very small capacity decay of 0.011% per cycle indicating a potential prospect.
