ABSTRACT:
The present invention provides a lithium battery comprising a cathode active material comprising an oxide of vanadium, which is a compound of the general formula M.sub.(1+y) (V.sub.3 O.sub.8).sub.2. M is a divalent ion having a +2 valency and y is equal to or greater than zero and preferably is less than 2. The vanadium oxide active material of the invention is prepared by a series of steps in which solid precursor compounds are successively finely divided and heat treated.
