Thermally activated ("thermal") battery technology
This, in turn, leads to even more thermal decomposition of FeS2, which can destroy the battery if thermal runaway occurs. A large voltage transient ("spike") occurs upon activation of a thermal battery if the FeS2 contains impurities such as oxides, sulfates, and elemental sulfur or if the activity of Li is not fixed in the cathode. This ...
