摘要：

In situ Mössbauer spectroscopy has been used to study the electrochemical reaction of lithium with KFeS2. Compositions KLixFeS2 with Δx = 0.25 were obtained by coulometric titration for one complete discharge and recharge. Mössbauer spectra were obtained at each composition. Three new iron sites are identified in addition to Fe3+ in KFeS2. A mechanism to account for the electrochemical and Mössbauer data is proposed. The end product KLiFeS2 has been synthesized and found to be body-centered tetragonal with a = 3.938(2) Å and c = 13.135(5) Å. © 1979.
