ABSTRACT:
The present invention provides a lithium battery comprising a cathode active material having as its major component amorphous V.sub.2 O.sub.5. The amorphous V.sub.2 O.sub.5 is prepared by electrochemically reacting crystalline vanadium pentoxide (V.sub.2 O.sub.5) with lithium in a cell to a voltage sufficient to transform crystalline vanadium pentoxide to amorphous vanadium pentoxide. Preferably, the electrochemical reaction is conducted in a V.sub.2 O.sub.5 --Li cell of about 1.5 V at a relatively constant current in a range of about 0.05 milliamps per cm.sup.2 to about 0.5 milliamps per cm.sup.2.
