Method for improving voltage regulation of batteries, particularly Li/FeS/sub 2/ thermal batteries
Patent
·
OSTI ID:6897825
In a battery composition useful as the cathode of a Li/-FeS/sub 2/ thermal battery, consisting essentially of substantially pure FeS/sub 2/, the improvement is described wherein sufficient lithium is added to the composition whereby the resultant composition falls into a three-phase thermodynamically invariant region of the Li/Fe/S phase diagram and has the formula Li/sub x/FeS/sub 2/ with the proviso that 0.05 less than or equal toxless than or equal to 1.5.
