Li/Fe_1-xCo_xS₂ system thermalbattery performance

摘要

Synthetic disulfides composed of iron and cobalt(Fe_1-xCo_xS₂) were evaluated as cathodematerials using a single cell. The discharge utilization was improvedand the discharge curve exhibited an excellent plateau when comparedwith those of both FeS₂ and FeS₂+CoS₂and also the discharge time became longer with an increasing Co atomicratio. The atomic ratio of iron and cobalt of each sample and thelattice constant obtained from X-ray analysis results are shown. Theperformances of BL 60210 and BL 72135 thermal batteries using syntheticdisulfide cathode materials are described
