ABSTRACT:
A process for preparing a compound using a vanadium oxide derivative for the cathode of a thermal cell. According to the invention, a powdered mixture is produced using vanadium pentoxide, a carbon, and a mixture of alkaline halides; then heat processing is conducted at a temperature ranging from 360.degree. C. to 650.degree. C. for a period ranging from 15 minutes to 2 hours inclusive.
A cathode material for a thermal cell is obtained which displays a stable discharge voltage (curve A).
