Abstract

Highlights: Highly graphitized GF was synthesized by usingc hemicalv apord eposition (CVD) that is never reported previously to the best of our knowledge. High reversible specific capacity (497 mAhg −1 ) was detected by using undoped graphene foam (GF) as anode material inl ithiumi onb attery (LIB). Excellent capacity retention was observed; as a result capacity fading was very small in comparison to the previous literature. Abstract: 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 (∼0.00578% at a current density of 200 mAg −1 ).
