采用水热法制备了LiFePO4/碳复合材料，并在氮气中进行了随后的热处理。微观结构观察表明，该复合材料颗粒细小，与碳混合均匀。以该复合材料为正极的电池表现出高倍率充放电性能。在1A/g电流密度下，复合材料的比容量比LiFePO4和碳粉的混合物大5个数量级。
LiFePO4/Carbon composite was prepared by hydrothermal synthesis and subsequent annealing in N2. From microstructure observation, fine particle size and homogeneous mixing with carbon in the composite were confirmed. A cell using the composite as cathode showed high-rate charge/discharge properties. The specific capacity of the composite at 1 A/g current density was 5 times of magnitude larger than that of mixture of LiFePO4 and carbon powders.
