However, its further application is limited due to the disad- vantages, such as low conductivity and badthermal stability, especially at high overload and open-circuit shelv- ing. Theexperimental results show that CoS2 with high conductivity, good chemicalstability andhigh decompo- sition temperature is expected to be the new cathode material to substitute FeS . Compared with the thermal 2 battery using FeS as cathode material, thethermal battery using CoS has similar capacity, low
