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 ε-phase silver vanadium oxide prepared by using a γ-phase silver vanadium oxide starting material. The reaction of γ-phase SVO with a silver salt produces the novel ε-phase SVO possessing a lower surface area than ε-phase SVO produced from vanadium oxide (VO) and a similar silver salt as starting materials. Consequently, the low surface area ε-phase SVO material provides an advantage in greater long term stability in pulse dischargeable cells.
