Nonaqueous Electrolyte Systems Ionic Transport in Nonaqueous Media

摘要

A compilation of research reports are given on work to investigate and describe ion transport in electrolyte-solvent solutions which may be useful for developing new fuel cell and battery systems. Various solvent-electrolyte solutions were tested for compatibility with lithium and for stability at strong oxidizing potentials. The density, viscosity, conductivity, and transference numbers were measured for various electrolytes in dimethyl sulfoxide, tetramethylene sulfoxide, and dimethyl sulfite. Lithium perchlorate dissolved in dimethyl sulfite was found to be a promising electrolyte solution. Lithium trifluoromethane sulfonate and lithium tetrafluoroborate were also found to be good electrolytes. Ionic transport properties of seven salts in dimethyl sulfoxide were found to be correlated well by established dilute solution theory developed for aqueous solutions. Beta-alumina appears to be a useful solid electrolyte for use in electrochemical systems. (Author)
