A method for preparing an amorphous ternary lithiated vanadium metal oxide of the formula LixMyVzO(x+5z+ny)/2, where M is a metal, 0<x</=3, 0<y</=3, 1</=z</=4, and n=2 or 3, comprising the steps of creating an aqueous solution of at least one metavanadate salt selected from the group consisting of NH4VO3 and NaVO3, and a nitrate salt of the formula M(NO3)n containing a large excess of a lithium salt; heating the solution; adding a sufficient amount of a base to obtain a suitable pH; and precipitating the amorphous lithiated vanadium metal oxide. A rechargeable lithiated intercalation battery cell comprising a positive electrode, a negative electrode, and an electrolyte, wherein the active material of the negative electrode is an amorphous ternary lithiated vanadium metal oxide of the formula LixMyVzO(x+5z+ny)/2 or an amorphous binary non-lithiated vanadium metal oxide of the formula MyVzO(5z+ny)/2, prepared according to the methods of the present invention. |
