Abstract

The use of polyorganodisulfides in a variety of solid-state batteries and electrochromic devices is discussed. Cycling data is presented for solid-state batteries using sodium and sodium-lead alloy negative electrodes with polyethylene oxide electrolyte and polydimercaptothiadiazole positive electrodes. Rate capabilities are comparable to that for analogous lithium batteries, but cells show continual deterioration with extended cycling. The use of polyorganodisulfide electrodes as optically passive counter electrodes for electrochromic devices is also described. Solid-state devices consisting of molybdenum doped WO3, amorphous polyethylene oxide electrolyte (aPEO), and a polyorganodisulfide counter electrode colored rapidly from a pale yellow to a deep bluegreen, upon application of 1.2 V dc. The photopic transmittance changed from 61 to 9%, and the solar transmittance from 45 to 5% during the coloration process.
