Graphene‐Encapsulated Si on Ultrathin‐Graphite Foam as Anode for High Capacity Lithium‐Ion Batteries

Abstract
A Si/graphene composite is drop-casted on an ultrathin-graphite foam (UGF) with three dimensional conductive network. The Si/graphene/UGF composite presents excellent stability and relatively high overall capacity when tested as an anode for rechargeable lithium ion batteries.
