Abstract

Layered Ni-rich oxide cathodes are susceptible to challenges with surface reconstruction and strain propagation, limiting their cyclability. The authors propose a solution involving oriented attachment-driven reactions, utilizing Wadsley–Roth nanocrystals and layered oxide to induce an epitaxial entropy-assisted coating, effectively addressing these issues.
