Effects of cathode materials on discharge characteristics of Li-B alloy/FeS_2 thermal battery

摘要

The effects of FeS_2 on the discharge characteristics of Li-B alloy/FeS_2 thermal battery had been studied. Results showed that 2.25/100 (mass fraction)Li_2O would be needed to rule out the voltage pulse in the first part of discharge curves for the FeS_2 powder of small particle size (<44 μm). After thermal decomposi - tion, the FeS_2 had transformed to Fe(1-x)S where x=0.24～0.066.
