dc.description.abstractEn | The electrochemical reaction mechanisms of FeP<sub><i>x</i></sub> (<i>x</i> = 1, 2, 4) as electrode materials in Li batteries were analyzed by <sup>57</sup>Fe Mssbauer spectroscopy, magnetic and NMR measurements. Depending on their stoichiometry, iron phosphides react with lithium along different pathways. FeP and FeP<sub>2</sub> are fully or partially converted to a composite electrode of Li<sub>3</sub>P and Fe. For both, the same intermediate phases, namely FeP and Li<sub><i>x</i></sub>FeP, were identified in cycling and FeP is partially regenerated on charge. Surprisingly, FeP<sub>4</sub> reacts with Li through an insertion type process previously identified for earlier transition metal phosphides (Ti, V, and Mn), and no conversion reaction to Li<sub>3</sub>P/Fe is observed. The long-term stability of the composite electrode Li<sub>3</sub>P/Fe<sub>0</sub> and of the intermediate phase Li<sub><i>x</i></sub>FeP is analyzed. | |
