Fes2 cathode
WebAlthough the cyclability of the FeS2/Na battery is poor, FeS2/Na battery has a large first discharge capacity of 758 mA h g-1. It corresponds to 85% of the theoretical capacity based on the 4.0 Na reaction per FeS2 (893 mA h g-1). According to the Fe K-edge XANES spectra of discharged FeS2 pellets, there were no clear traces of iron valence change. WebThe FeS2 cathode material is obtained as beneficiated ore from naturally occurring pyrite deposits or as a by-product flotation concentrate from the processing of base or noble metal ores. It is highly unusual to find a naturally occurring sub- stance used directly as a principal ingredient in a chemical ...
