Regulating Phase Transition and Restraining Fe Distortion at High Potential Window via Rare Earth Metal Incorporation on O3‐Type Layered Cathodes

Rapid capacity fading and structural collapse, along with other deep‐rooted challenges in the high‐voltage region, are insufficient to meet the requirements for commercial applications of O3‐type layered cathodes. Hereby, rare earth metal (RE) within the IIIB group are utilized as the robust dopants...
