Ta 5d‐Orbital‐Mediated Local Electronic‐Structure Regulation Enables Durable 4.7 V LiCoO 2 Cathodes

Raising the cutoff voltage of LiCoO 2 (LCO) is an effective route to increase energy density, yet it inevitably aggravates lattice oxygen instability, interfacial parasitic reactions, and bulk structural degradation under deep delithiation. Herein, we propose a tantalum (Ta)‐enabled local spin regulation strategy...
