| Abstract: | The development of methods to synthesize electrode materials can improve the performance of lithium ion storage. In this study, a facile and low-cost approach is employed to synthesize LiFePO4 (LFP/NC) hybrid materials decorated with nitrogen-doped carbon nanomaterials (NC). Melamine was used as nitrogen and carbon source with an NC to LFP ratio of 3.19%. As electrode materials for lithium ion batteries (LIBs), the LFP/NC composites exhibit an optimum performance with a high rate capacity of 144.6 mAh·g?1 at 1 C after 500 cycles without apparent loss. The outstanding cycling stability may be attributed to the synergetic effects of well-crystallized particles and NC layers. |
