OPTIMISING A NEW SYNTHESIS ROUTE FOR LiFePO4/C COMPOSITES

LiFePO4/C composites were synthesised from an aqueous solution that contained LiNO3, Fe(NO3)3.9H2O, NH4H2PO4 and sucrose. Sucrose was used as a synthesising agent and carbon source. The LiFePO4/C composites were synthesised under various conditions such as the calcination temperature and amount of s...

Summary:LiFePO4/C composites were synthesised from an aqueous solution that contained LiNO3, Fe(NO3)3.9H2O, NH4H2PO4 and sucrose. Sucrose was used as a synthesising agent and carbon source. The LiFePO4/C composites were synthesised under various conditions such as the calcination temperature and amount of sucrose to optimise the new synthesis route. The electrochemical properties of the composites as a function of calcination temperature and amount of sucrose were investigated. The LiFEPO4/C composite synthesised at 750 C with 6.85 wt% residual carbon showed a high discharge capacity 134 mAh/g at a current density 100 mA/g.
