摘要：

A compound "vacuum firing and water quenching" technique was presented in the synthesis of LiFePO4 cathode powder. The sample was prepared by heating the pre-decomposed precursor mixtures sealed in vacuum quartz-tube, followed by water quenching at the sintering temperature. The results indicate that using the "fast quenching" treatment can succeed in controlling overgrowth of the grain size of final product and improving its utilization ratio of active material. The sample synthesized by this technique has the high reversible discharge specific capacity and good cyclic electrochemical performance. (c) 2007 Xu Guang Gao.
