Abstract : The investigation of electrochemical energy conversion systems has involved work on three tasks. The first deals with high energy galvanic cells, particularly cells based on non-aqueous organic solvents. Preliminary to the investigation of cathode depolarizers based on nitrogen heterocyclic compounds some measurements were made on the chemical stability of Li in saturated solutions of organic depolarizers. Rough determinations indicate that Li is stable in the presence of compounds with the furoxan type structure. The second task deals with the mathematical analysis of electrochemical energy conversion processes. Analyses of vehicle velocity-acceleration profiles were made which will be used as an aid in sizing batteries to be used in vehicle propulsion. Postulates were made of typical vehicle operation, including a velocity-acceleration-time power requirement load profile. This profile will allow estimation of battery requirements to operate a vehicle in a typical driving situation. The third task of an exploratory nature projects work on a new type of solid electrolytes - a proton conductor - that might provide improved battery electrolytes and separators. (Author)
