Abstract : A new rectangular cell with more practical geometry and more uniform current density was constructed. Utilization efficiencies for lithium anodes were determined in this cell with lithium bromide in propylene carbonate and dimethyl sulfoxide as electrolytes. In the latter case, 90% efficiency was obtained. An improved electrode holder suitable for utilization measurements on powdered cathode materials was also developed and tested experimentally. The water absorbed by lithium bromide solutions in propylene carbonate and dimethyl sulfoxide during controlled exposure to moist air was determined, and the effect of this increase in water content on the behavior of silver oxide cathodes was investigated. Cathode performance is the greatest limitation to development of a complete cell with the desired energy density. (Author)
