Site-specific gradient Y/F co-doping modulating electronic structure for durable O3-type sodium layered oxide cathodes

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...
