Abstract
The electrochemical system lithium-iodine pentoxide, attractive because of its high theoretical energy density, was investigated, employing as electrolyte a variety of salts dissolved in polar organic solvents. Iodine pentoxide blended with graphite and pressed on an expanded silver grid served as cathode; the anodes were made by pressing lithium ribbon onto an expanded nickel grid. Of the salt-solvent combinations tried, potassium perchlorate dissolved in dimethylsulfoxide was most satisfactory; even with the combination the fraction of the theoretical energy density realized amounted at most to about 12%.
