Three-Dimensional Graphene-Like Carbon Prepared from CO as Anode Material for 2 High-Performance Lithium-Ion Batteries

Three-Dimensional Graphene-Like Carbon Prepared from CO as Anode 2 Material for High-Performance Lithium-Ion BatteriesAs a typical greenhouse gas, carbon dioxide (CO ) has significant negative impacts on the environment, and hence, harmless treatment of CO has 2 2 become very important.In this paper, we present a two-step approach for the preparation of three-dimensional graphene-like carbon (3D-GC) from 2 CO .The 3D-GC sample had abundant micropores and nanopores on the carbon framework and its specific surface area was as high as 927 m /g.2 Furthermore, the 3D-GC electrodes showed excellent electrochemical performance when used as the anode material in lithium-ion batteries.The reversible capacity was 705 mA h/g after 100 cycles at 100 mA/g and the rate capability was 252 mA h/g at 5000 mA/g.
