摘　　要：以LiCO3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LiV3O锂离子正极材料。通过TG-DTA得出该合成反应的机理及其动力学模型。考察了合成条件对产物的影响。结果表明:550℃左右烧结24 h可得到单一相产物LiV3O8。TEM图显示其形貌及粒度都较好。Using LiCO3 and V205 as material,the lithium vandium oxide LiV308 prepared by solid state ligand reaction method, the synthesis reaction mechanism and its dynamic model are obtained by TG - DTA. The effect of synthesis condition to products ane investigated. The resule shows, sintering 24 h un- der 550 ℃ ,the single- phase LiV308 can obtained. The morphology and radius are good by TEM image observation.
