文摘

A graphene aerogel supporting LiFePO4 nanoparticles is facilely synthesized. LFP/GA presents remarkably improved Li-insertion performance than LFP and LFP/G. The enhancement is ascribed to the synergistic interactions between LFP and GA. The graphene content has a significant effect on the electrochemical performance.
