Capacity fading of lithium ion batteries (LIBs) is a huge hurdle for their commercial utilization that may be reduced by the insertion of high quality anode material. Herein, we introduce high-graphitized graphene foam (GF) as anode material, which can be helpful for minimizing the loss of specific capacity during electrochemical reactions. GF shows excellent results when employed as anode in LIBs with high capacity values of 497 mAhg(-1) along with very low capacity fading (similar to 0.00578% at a current density of 200 mAg(-1)).
