| Popis: | An externally heated thermal battery (EHTB) using an LiAl/Ag 2 CrO 4 couple was developed to meet the unusual requirements of an open circuit stand of 8 h. The battery was designed to maximize the voltage output, to control cathode growth and corrosion of cell components, and to minimize passivation of pellets during wet stand. The final design of the EHTB consisted of three parallel strings of two cells for a total of six individual cells. The battery exhibited a stable OCV from 5.75–5.77 V throughout a slow temperature ramp at 3.3 °C/h from 120–149 °C and yielded currents in excess of 2.5 A when pulsed for 50 ms through a 1 Ω load. |
