Layered oxide cathodes have attracted wide research interest due to their controllable synthesis, tuneability, and high energy density in sodium-ion batteries (SIBs). However, in layered oxide cathodes, capacity retention is unsatisfactory due to structural changes, and the severity of capacity fading increases at higher voltages. Chemical heterogeneity and concentration gradient lead to the co-existence of […]
