Abstract
The current invention relates to the preparation of an improved cathode active material for non-aqueous lithium electrochemical cell. In particular, the cathode active material comprises &egr;-phase silver vanadium oxide prepared by using a &ggr;-phase silver vanadium oxide starting material. The reaction of &ggr;-phase SVO with a silver salt produces the novel &egr;-phase SVO possessing a lower surface area than &egr;-phase SVO produced from vanadium oxide (V O ) and a similar silver salt as starting materials. Consequently, the low surface area &egr;-phase SVO material provides an advantage in greater long term stability in pulse dischargeable cells.
