Effect of carbon type and processing on high-rate thionyl chloride cathode collectors. Interim technical report
This study was initiated to determine the effects of carbon type, treatment and additives and the manufacturing process on high rate performance of thionyl chloride cathode collectors. Seventeen different collector materials and treatments were tested in demountable test cells and the results compared on the basis of capacity and energy per unit void volume of the cathode collector. Superior results were consistently obtained from CoTMPP catalyzed carbons and from carbon microfibers. Better voltage results were obtained from Ketjenblack EC, but the capacity was not consistently better than acetylene black. Process conditions did not show strong correlations, but in some cases there appears to be a best process for a given carbon type. A significant high rate (7 A test) capacity improvement was seen in F cells with a carbon fiber electrode in agreement with test cell results. Other test cells results did not correlate well with F cell tests, but further work is required to establish statistical significance.
