Abstract

Abstract: 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.

Key words: LiFePO₄/C, nanoparticle, super heated water
