Additive for iron disulfide cathodes used in thermal batteries

Patent ·
OSTI ID:6775559
The invention comprises thermal batteries employing an FeS/sub 2/ depolarizer itself. A minor amount of CaSi/sub 2/ preferably 1-3% by weight is provided as an additive in the FeS/sub 2/ depolarizer to eliminate the voltage transient (spike) which normally occurs upon activation of batteries of this type. The amount of FeS/sub 2/ by weight generally comprises 64 to 90%.
