New Materials for Electrochemical Cells
Abstract
Determination of the thermochemical, structural and basic electrochemical properties of mixed electronic/ionic conductors was successfully carried out on the following systems: H(x)MoO3, Li(x)V2O5, H(x)WO3, and Li(x) MoO3. Attempts to design new protonic and Li(+)ion conductors have opened up two fields: One is the recognition of particle hydrates as protonic electrolytes capable of fabrication into dense ceramics by cold pressing; we have obtained room-temperature H(+)ion conductivity approaching .01/ohm/cm in cold-pressing Sb(.2)O(5.5).4H2O. The other is the use of low-temperature chemical and electrochemical techniques to prepare new materials not attainable with high- temperature techniques. With this method we have prepared Li/Li (1-x) Cobalt dioxide cells having open-circuit voltages in excess of 4 V. We have also initiated studies into composite electrolyte/electrode materials using room- temperature molten salts immobilized by insertion-compound electrode materials. (AW)
