文摘

Phase-pure nano-LiFePO4 was successfully fabricated under hydrothermal condition at different temperatures. We found that the obtained particle morphologies and sizes were temperature-dependent. Compared with other samples, the as-received LiFePO4 synthesized at 200°C for 3 h presented monodisperse state. Moreover, this product possessed excellent electrochemical performance and cycling stability after annealing at 700°C for 1 h with glucose as carbon source.
