▎ 摘 要
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 mA h g(-1) at a current density of 20 mA g(-1), and a capacity of 231 mA h 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. (C) 2016 Elsevier B.V. All rights reserved.
