A novel synthetic route for LiFePO4/C cathode materials by addition of starch for lithium-ion batteries
摘要:
LiFePO4/Carbon composite cathode material was prepared using starch as carbon source by spray-pelleting and subsequent pyrolysis in N2. The samples were characterized by XRD, SEM, Raman, and their electrochemical performance was investigated in terms of cycling behavior. There has a special micro-morphology via the process, which is favorable to electrochemical properties.The discharge capacity of the LiFePO4/C composite was 170 mAh g-1, equal to the theoretical specific capacity at 0.1 C rate. At4 C current density, the specific capacity was about 80 mAh g-1, which can satisfy for transportation applications if having a more flat discharge flat.
