Superlithiophilic Amorphous SiO₂-TiO₂ Distributed into Porous Carbon Skeleton Enabling Uniform Lithium Deposition for Stable Lithium Metal Batteries.

ABSTRACT: Lithium (Li) metal anodes have garnered increasing interest in recent years as its high theoretical capacity and low electrochemical potential promises a myriad of opportunities for various applications. However, one critical issue to overcome is the inhomogeneous deposition of Li⁺ during the plating and stripping process. This inhomogeneous deposition could result in uncontrollable dendrite growth, further leading to poor coulombic efficiency, shorter lifecycles, and safety concerns due to internal short circuit and thermal runaways. To address these issues, a 3D porous core-shell fiber scaffold is presented, comprising of well-dispersed SiO₂, TiO₂, and carbon, as superlithiophilic host materials for lithium anodes. The amorphous SiO₂ and TiO
