摘要：
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. © 2016 WILEY-VCH Verlag GmbH & Co.
