Accelerating lithium-ion pre-desolvation and transport via glassy MOF for fast-charging and high-energy-density lithium-ion batteries.

ABSTRACT: Conventional graphite anodes in lithium-ion batteries (LIBs) suffer from limited fast-charging capability and lithium dendrite growth, particularly at high current densities. This work introduces a glassy metal-organic framework (MOF glass) that simultaneously enables easy lithium-ion pre-desolvation and fast Li⁺ transport. The MOF glass-coated graphite (glass@graphite) forms a distinctive double-layer structure during initial discharge: an electron-insulating outer layer with rigid 2.93 Å pores that facilitates easy Li⁺ pre-desolvation, and a Li₃P-rich inner layer that ensures rapid lithium-ion conduction. The outer layer's pre-desolvation effect generates a highly aggregated electrolyte within MOF channels, promoting formation of a stable anion-derived LiF-dominated solid electrolyte int
