Lithium vanadium oxides have been prepared by the direct reaction of an aqueous hydrogen peroxide solution with lithium and vanadium alkoxides، نويسنده , , LiO-n-C3H7 and VO(O-i-C3H7)3. The ?-like phase oxide can be obtained at the nominal lithium content xn=3 almost as a single phase. From the thermogravimetric (TG) measurement، نويسنده , , it was revealed that the ?-like phase oxide contained water and organic compounds، نويسنده , , and the water content n in LixV2O5·nH2O was found to be about 2.4 for ?-like phase oxide. Water content of the ?-like phase oxides، نويسنده , , controlled by heat-treatment at various temperatures، نويسنده , , affects charge and discharge behaviours markedly. It should be noted that the average potential of Li2.2V2O5·nH2O is at least 1 V higher than that of ?-LiV2O5.، نويسنده ,
