Nitrogen and phosphorus dual-doped graphene oxide was prepared by directly calcining a mixture of pure graphene oxide, urea (nitrogen source), and 1,2-bis(diphenylphosphino)methane (phosphorous source). The morphology and composition of the obtained dual-doped graphene oxide were confirmed by SEM, TEM, XRD pattern, Raman spectrum, and XPS. The nitrogen and phosphorous dual-doped graphene oxide was tested as an anode material of lithium-ion batteries (LIBs). The cycle and rate performance of the dual-doped graphene oxide were also examined. The dualdoped graphene oxide exhibited a superior initial discharge capacity of 2796 mAh·g−1 and excellent reversible capacity of 1200 mAh·g−1 at a current density of 100 mA·g−1 after 200 charge/discharge cycles, suggesting that the dual-doping of nitrogen and phosphorous is an effective way to enhance lithium-ion storage for graphene oxide.

Lithium ion (Li-ion) batteries have been widely applied to portable electronic devices and hybrid vehicles. In order to further enhance performance, the search for advanced anode materials to meet the growing demand for high-performance Li-ion batteries is significant. Fe3C as an anode material can contribute more capacity than its theoretical one due to the pseudocapacity on the interface. However, the traditional synthetic methods need harsh conditions, such as high temperature and hazardous and expensive chemical precursors. In this study, a graphitic carbon encapsulated Fe/Fe3C (denoted as Fe/Fe3C@GC) composite was synthesized as an anode active material for high-performance lithium ion batteries by a simple and cost-effective approach through co-pyrolysis of biomass and iron precursor. The graphitic carbon shell formed by the carbonization of sawdust can improve the electrical conductivity and accommodate volume expansion during discharging. The porous microstructure of the shell can also provide increased active sites for the redox reactions. The in-situ-formed Fe/Fe3C nanoparticles show pseudocapacitive behavior that increases the capacity. The composite exhibits a high reversible capacity and excellent rate performance. The composite delivered a high initial discharge capacity of 1027 mAh g−1 at 45 mA g−1 and maintained a reversible capacity of 302 mAh g−1 at 200 mA g−1 after 200 cycles. Even at the high current density of 5000 mA g−1, the Fe/Fe3C@GC cell also shows a stable cycling performance. Therefore, Fe/Fe3C@GC composite is considered as one of the potential anode materials for lithium ion batteries.
