Figure 9. Illustration of potential reaction pathway of Cu1-xFexF2 during discharge-charge. During discharge (stages I and II), Cu and Fe occur sequentially by the conversion reduction. During charge, the oxidation processes of Fe and Cu (stages III and IV) overlap to reform the disordered rutile-like Cu-Fe-F phase. Reproduced from Ref.[122] with permission.
