... electrolyte decomposition and the reversible conversion reaction of lithium ion intercalation to form Li 2 O. An anodic peak is also present at about 1.75 V, corresponding to the reversible oxidation of Fe 0 to Fe 3+ . ... shorter pathways in the nanorods for lithium ion diffusion. Thus, the elec- trochemical performance of the one-dimensional nanostructured electrodes is remarkably enhanced. 4. Conclusion In summary, single ... the nano-Fe 2 O 3 performance as anode material for lithium ion batter- ies [24,25]. Nanosize materials have large surface areas and high surface energy. For lithium ion battery applications, the large...
