摘要
本文采用高温固相合成法合成LiMnPO4,通过用碳包覆法改变其电导率,并用水淬冷法与传统的自然冷却法制备。通过XRD,SEM和充放电测试等手段,发现水淬冷法制得LiMnPO4比自然冷却法所得材料的粒径要小,且首次放电比容量高。
LiMnPO4/C cathode material was synthesized by high temperature solid state method,and the effect of water quenching and common cooling mode on the microstructure and electrochemical performance of LiMnPO4/C was studied.X-ray diffraction(XRD),scanning electron microscopy(SEM),and charge-discharge test was used to study the LiMnPO4/C.The result of the experiment shows that the morphology of the samples by water quenching is smaller than that by common cooling mode.Therefore,the initial specific charge of the samples by water quenching is better than that by common cooling mode.
