Lithium polycarbon fluoride cells

The (CF ), cathode is stable in contact with organic electrolyte systems, and the cells have a satisfactory shelf life. In common with other lithium power sources, polycarbon fluoride-based cells may suffer from voltage delay, but only under severe discharge conditions. 

Polycarbon fluorides of the general formula CV n can be obtained by direct fluorination of carbon black or other varieties of carbon at high temperatures. Theoretical specific energy density 2600 Wh kg can be achieved with these materials. Lithium cells with polycarbon fluoride cathodes have an open-circuit voltage in the range of 2.8-3.3 V, depending on the composition of the cathode material. A typical cell reaction may be written [64] ...
