Abstract
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.
