  • Additive for iron disulfide cathodes used in thermal batteries
    Patent number: 4383014
    Abstract: The invention comprises thermal batteries employing an FeS.sub.2 depolarizer, i.e. cathode material, and the 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 64-90%.
