High valence pillar engineering toward near-zero-strain structural reversibility in high entropy layered oxide cathode.

O3-type layered oxides are attractive cathode candidates for rechargeable sodium-ion batteries (SIBs) due to their favorable energy density and straightforward synthesis. However, such materials undergo intricate phase transformations and pronounced structural degradation, leading to rapid electrode failure. Herein, a...
