Voltage suppression is an important problem in the Li/CF.sub.x battery system. The voltage that a Li/CF.sub.x battery will deliver just after the circuit has been closed can be as low as the voltage near the end of battery life. Electronic circuitry powered by Li/CF.sub.x batteries are complicated by the need to design around this problem. The processing of fluorinated carbon (CF.sub.x) to lower the initial voltage suppression is disclosed wherein fluorinated carbon is treated with a Group IA metal-alkyl or -aryl compound. The reaction between these compounds (e.g., n-butyl lithium) and the fluorinated carbon produces a battery grade product which undergoes reduced to almost no suppression of the initial closed circuit voltage.

Inhibiting voltage suppression in lithium/fluorinated carbon batteries

A means to eliminate the suppression of the closed circuit voltage of a Li/CF.sub.x battery during the initial part of its discharge is effected by blending an additive CF.sub.x which does not show significant voltage suppression with the (bulk) CF.sub.x that is normally used in fabricating cathodes for such batteries. Blending is used to get a mixture which has substantially minimized voltage suppression and has good capacity. The closed circuit voltage of a Li/CF.sub.x battery during the initial 10% of discharge is known to be lower than the closed circuit voltage during the later stages. This characteristic adversely impacts applications since the voltage at beginning of life is as low as the voltage indicating end of life, complicating design of circuitry to indicate end of life. In the disclosure, the material with no significant voltage suppression discharges preferentially at the beginning of discharge leading to higher voltage and no suppression. The bulk material also discharges to some extent during this early stage of discharge. When the small percentage of coke-based CF.sub.x additive is depleted, the bulk CF.sub.x has discharged to the point that it no longer shows voltage suppression.
