O3-type transition metal oxides (TMOs) are among the most promising cathodes for sodium-ion batteries (SIBs) due to their high capacity. However, the local electronic structure arrangement around transition metals (TM) cations directly affects the phase transition behavior and oxygen redox chemistry upon cycling. H...

P2-type layered transition metal (TM) oxides have emerged as promising cathode candidates for sodium-ion batteries (SIBs) owing to their intrinsic air stability and open prismatic diffusion pathways. However, at moderate (de)sodiation, severe structural breakdown and performance failure associated with the intra-partic...
