摘　　要：以Li2CO3和V2O5为原料,采用固相配位化学反应法合成了层状锂钒氧化物LiV3O8。通过透射电子显微镜法(TEM)观察,所得产物具有较小的晶粒。充放电结果显示,电流密度为0.5mA/cm2,充放电区间为1.5～4.0V时,首次充放电比容量达到210mAh/g,高于同等条件下传统方法制备所得产物的首次放电量,具有很好的储存性能。Lithium vanadium oxide LiV3O8 used as the cathode of lithium ion batteries was made by a new solid state reaction of coordination method, TEM images show that the LiV3O8 compound made by this new method has a good morphology compared with that prepared by traditional synthesis method, The discharge-charge properties in the first cycle is better than that prepared by traditional synthesis method, with a discharge specific capacity of 210 mAh/g.
