Galvanic high energy cells with molten electrolytes
High energy galvanic cells as energy stores offer the potential of about 40% better utilization of primary energy for vehicular and also stationary power production, especially where peak loads are concerned. The objective was to produce fused salt cells of high specific energy and high specific power (150 Ah for 5 hour rate) and 80 Wh/kg. 29 Electrochemical couples were tested for a range of factors and LiAl/FeS using specially prepared FeS appeared most suitable for development of a 200 Ah prototype cell. Detailed studies were made of separators, positive current collectors, swelling phenomena and discharge kinetics of model electrodes. Post-test examination studied causes of cell failure, and a preliminary cost-benefit analysis was made.
