A novel kind of phenol formaldehyde resin and graphene composites were fabricated through

spray drying. We synthesized a three-dimensional network structure composites, in which phenol formaldehyde resin offers large lithium storage and graphene layers can provide a highly conductive matrix to enable good contact between particles and facilitate the diffusion and transport of ions. The composite electrodes display a large reversible capacity of 302 mAh g-1 at a current density of 20 mA g-1, and a capacity of 231 mAh g-1 at 100 mA g-1. After 200 cycles, the capacity retention of composite anodes is almost 99%, further confirming the predominance of this new material for lithium storage.
