Well-dispersed LiFePO4 nanoparticles anchored on a three-dimensional graphene aerogel as high-performance positive electrode materials for lithium-ion batteries
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.
