Abstract

Mesoporous silicas tethered with anions were developed as quasi-solid electrolytes for Li-metal batteries. The high grafted density of trifluoromethylsulfonyl (-NTf^-) groups and their uniformly distributed negative charge endow MCM41-NLiTf with a room temperature single Li-ion conductivity of up to 2.4 × 10^-4 S cm^-1, which enables stable cycling of LFP‖Li batteries.
