摘要: A rapid and continuous method for production of LiFePO4/C nanoparticles in super heated water is described,wherein soluble starch was used as carbon precursor.The effects of pH,flow rate,temperature,and pressure on the formation of LiFePO4/C particles were investigated.Results showed that the pH value was the key factor on the formation of phase pure LiFePO4,which only formed at pH=7;the LiFePO4/C occurred as particles with about 70-200 nm size and LiFePO4 was covered by a thin carbon layer;higher flow rate,higher pressure,and lower temperature led to smaller particles of LiFePO4/C.
