摘要：

Li2MnSiO4 cathode materials were synthesized by high temperature solid-state reaction.The synthesis process was investigated by thermogravimetric-differential scanning calorimetry(TG-DSC).The results show that there are two main mass loss stages due to the dehydration and thermal decomposition of raw materials.There are ve endothermic peaks appeared in DSC curves obtained at different heating rates.According to the thermal analysis,the apparent activate energy of three endothermic peaks(200 ℃) is calculated to be 384.12、120.63,263.43 kJ/mol and 350.78,117.16,227.59 kJ/mol using the Doyle-Ozawa method and the Kissinger method,respectively.In the Kissinger method,the corresponding reaction order,frequency factor and reaction rate equation are further inferred.The results of X-ray diffraction(XRD) show the step-sintering method proposed from the thermal dynamics results can be used to produce better optimized-Li2MnSiO4.
