Abstract :
The authors studied and developed a new cathodic compound for thermal batteries, based on a derivative of vanadium pentoxide and carbon. This compound presents a flat discharge plateau of 2.15 V vs LiAl (at a discharge current of 0.2 A/cm2), i.e., a gain of 400 mV with respect to FeS2. The synthesis route of the material was studied and tested in single cell versus LiAl anodes to optimize the discharge efficiency. Discharge performances are good up to 1 A/cm2. In order to get a better knowledge of its potential, and to take complete advantage of its high energy density, the optimized material was then tested in batteries of various configurations
