Abstract
Abstract 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 for O3‐NaNi 1/3 Fe 1/3 Mn 1/3 O 2 (NFM) to achieve the purpose of reconstructing the crystal lattice and regulating the interlayer structure. The inactive RE 3+ acts as a pillar, reinforces the TMO 6 octahedron, and broadens the Na + diffusion layer in the configuration of O‐Na‐O‐TM (RE)‐O‐Na‐O, giving rise to the enhanced crystal stability and accelerating the transmission of sodium ions.
