摘要 The influence of factors of the carbon black content, sintering temperature, sintering time, molar ratio of Li to Fe, as well as the electrochemical properties of LiFePO4 for lithium ion battery were studied. The only technology was obtained by using range analysis through Latin orthogonal experiment of L44（16）. The results show that the optimization synthesis technology of LiFePO4 is content of 5% doping carbon, sintering temperature of 700℃, molar ratio of Li to Fe of 1.03∶1 and sintering time of 16h.The optimized cathode synthesis techniques can make LiFePO4 have good electrochemical properties.
