Realizing Scalable Nano-SiO₂-Aerogel-Reinforced Composite Polymer Electrolytes with High Ionic Conductivity via Rheology-Tuning UV Polymerization.

ABSTRACT: Polymer electrolytes for lithium metal batteries have aroused widespread interest because of their flexibility and excellent processability. However, the low ambient ionic conductivity and conventional fabrication process hinder their large-scale application. Herein, a novel polyethylene-oxide-based composite polymer electrolyte is designed and fabricated by introducing nano-SiO₂ aerogel as an inorganic filler. The Lewis acid-base interaction between SiO₂ and anions from Li salts facilitates the dissociation of Li⁺. Moreover, the SiO₂ interacts with ether oxygen (EO) groups, which weakens the interaction between Li⁺ and EO groups. This synergistic effect produces more free Li⁺ in the electrolyte. Additionally, the facile rhe
