Open-ended Terms Thermal batteries. The diffusion coefficient of Ag in KCl-LiCl was determined. The value differed from data obtained by chronopotentiometry by a factor of 7. The experiment is to be rerun using radioactive tracer techniques for greater sensitivity. About 250 test cells, principally involving CuO, variou sulfates, and phosphates, were prepared and evaluated. Based on active material alone anode weight plus the calculated amount of cathodic material for complete reaction CuO gave a maximum of 282 whrlb the phosphates and sulfates gave maximums of 256 and 310 whrlb, respectively. On the basis of total balanced cell weight, the phosphates gave a maximum of 175.1 whrlb while the sulfates gave 141 whrlb CuO on the same basis gave 182.4 whrlb.
