Suppressing electrolyte-lithium metal reactivity via Li⁺-desolvation in uniform nano-porous separator.

ABSTRACT: Lithium reactivity with electrolytes leads to their continuous consumption and dendrite growth, which constitute major obstacles to harnessing the tremendous energy of lithium-metal anode in a reversible manner. Considerable attention has been focused on inhibiting dendrite via interface and electrolyte engineering, while admitting electrolyte-lithium metal reactivity as a thermodynamic inevitability. Here, we report the effective suppression of such reactivity through a nano-porous separator. Calculation assisted by diversified characterizations reveals that the separator partially desolvates Li⁺ in confinement created by its uniform nanopores, and deactivates solvents for electrochemical reduction before Li⁰-deposition occurs. The consequence of such deactivation is
