A screening program was carried out to investigate the electrochemical behaviour of several organic and inorganic cathodes when discharged in non-aqueous electrolytes. The majority of the materials discharged only poorly with the exception of AgO, bis-benzo furoxane sulphone and m-dinitrobenzene. These compounds gave results warranting further study. Statistical analysis of the preparative variables of the silver oxide cathode revealed that optimum performance is achieved with a cathode containing no binder or conducting additive. A Latin Square analysis of the floc method of preparing CuF2 cathodes revealed that the performance was in general lower than the hot pressed types. Promising results were obtained from hot pressed CuF2 electrodes discharged in 2F LiC104Dimethyl carbonate. When discharged at 7 masq cm the cathodes gave 60 coulombic efficiency compared to 60 utilization at 2 masq cm in 1F LiC104P.C. Solubility studies of CuF2 in solutions of LiC104 in propylene carbonate have shown that a major cause of the dissolution of CuF2 is the impurities in the LiC104. Author
