Facilitating Sodium‐Ion Diffusion in Fe‐Doped Co3O4 for High‐Rate Performance
Small, EarlyView.The limited rate performance of cobalt oxide (Co3O4) materials restricts their applicability in the rapid charge–discharge process of sodium‐ion batteries (SIBs). Iron (Fe) lattice doping can facilitate sodium‐ion diffusion by narrowing the bandgap and modulating the Co─O bond length.
