Reaction mechanism for the Fe0.9Co0.1OF cathode. a The relationship between the overpotentials and the metal critical particle sizes during lithiation for FeOF and Fe0.9Co0.1OF. b The relationship between the in situ-formed metal particle size with the equilibrium potential of the conversion reaction. c Calculation reaction curves of the Fe0.9Co0.1OF materials from the DFT intercalation of Li into Fe0.9Co0.1OF, and the conversion path using the equilibrium phases (assuming the size of metal particles is 1 nm). d Illustrations of structural evolution for FeOF and Fe0.9Co0.1OF during lithiation
