Strain-Retardant Sodium Layered Cathodes Enabled by Conformal Octahedral Matching.
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...
