ABSTRACT:
A rechargeable electrochemical cell whose anode is based on lithium or a lithium alloy, whose electrolyte is constituted by a solution of a lithium salt in a non-aqueous solvent, and whose cathode material is based on crystallized vanadium oxide, wherein the vanadium oxide contains a .gamma.' phase due to chemical or electrochemical oxidation of a .gamma. phase of LiV.sub.2 O.sub.5 obtained by inserting a number of atoms of lithium per mole of V.sub.2 O.sub.5 into said oxide, where said number lies in the range 0.9 to 2.
