摘　　要：作者以酚醛树脂作为碳源,合成了一系列LiFePO4/C.通过XRD物相分析和晶粒度分析,给出LiFePO4晶粒度与反应温度T、反应时间t之间较完整的函数关系,并求出反应的表观活化能,为优化实验条件提供理论依据.A series of LiFePO4/C were synthesized by using phenol-formaldehyde resin as the carbon source. Based on the analysis of XRD phase and crystalline grain size, the relationships between the crystalline grain size of LiFePO4, the calcining temperature T and reaction time t were given. The apparent activation energy E was calculated. The relationship and the value of E are important for optimizing experimental conditions.
