The performace of material was tested by DSC,XRD,SEM,EIS and charge-discharge cycles . The influences of various synthesized condition , sintering time and the amount of F were studied and correlative technics parameter to improve performance of material were optimized. DSC shows that three endotherimc peaks and one large exothermic peak are observed in the temperature range 150-400℃, which is because of the removal of water,the decomposition of the organic constituents and the formation of spinel. Only the citrate precursor is sintered at least 450℃, the crystallinity of spinel phase could be formed intactly.

通过DSC、XRD、SEM、EIS和充放电循环等手段对材料进行性能测试，比较了不同合成温度、烧结时间和不同掺杂元素量等条件对材料性能的影响，优选出提高材料性能的相关工艺参数， DSC表明，采用溶胶-凝胶-络合法制备的前驱体在150-400℃中有三个小的吸热峰和一个大的放热峰，这是前驱体中的水分、柠酸酸及其盐和醋酸及其盐在蒸发及分解，柠檬酸前驱体至少需在450℃以上才可能形成完整的尖晶石材料。
