Abstract

A LiFePO4/nitrogen-doped reduced graphene oxide nanocomposite was synthesized using a solution-based method followed by heat treatment. The nitrogen-doped reduced graphene oxide surrounding the LiFePO4 nanoparticles facilitates the transfer of electrons throughout the electrodes, which significantly reduces the internal resistance of the electrodes, resulting in high utilization of LiFePO4. Electrodes fabricated with the LiFePO4/nitrogen-doped reduced graphene nanocomposite show high discharge capacities and voltages at high rates including sub-zero temperature conditions, even at commercially acceptable loading levels.
