Surface Chemical Coordination Stabilizes Ni-Rich Cathodes for High-Energy Li-Metal Batteries.

The stability of the electrode-electrolyte interface is a critical factor influencing the electrochemical performance of Li-metal batteries. However, on the delithiated Ni-rich cathode surface, the strong catalytic effects of transition metals with coordination deficiency significantly aggravate the parasitic reactions with Li-metal-compatible ether-based electrolytes, thereby reducing the cycling stability of high-voltage Ni-rich batteries. Here, we propose an -induction mechanism to address coordination deficiency through the coupling of interfacial orbitals between molecules and the cathode surface.
