Abstract
The use of vanadium oxide iron and/or aluminium bronzes as a cathode material in electrochemical generators is described. The cathode material is a vanadium oxide bronze having formula: M.sup.1.sub.x1 M.sup.2.sub.x2 V.sub.2 O.sub.5, wherein M.sup.1 is a vanadium oxide bronze or iron, M.sup.2 is a metal different from M.sup.1 having valency n and chosen from alkali metals, alkaline earth metals, transition metals and aluminium, and x.sub.1 and x.sub.2 are such that 0.06.ltoreq.x.sub.1 .ltoreq.0.13; 0.ltoreq.x.sub.2 .ltoreq.0.20; and 0.27.ltoreq.3x.sub.1 .ltoreq.nx.sub.2 .ltoreq.0.39; and may be combined as a cathode (9) with an Li or Li alloy anode (5) and with an electrolyte consisting of lithium perchlorate in propylene carbonate.
