Summary: The emerging localized high-concentration electrolytes (LHCEs) with small salt dosage, low viscosity, and favorable electrode wettability have triggered extensive research interest recently. In this study, an anode-compatible and high-voltage ether-based LHCE (BTF-LHCE) is proposed by introducing cost-efficient and lightweight benzotrifluoride (BTF) as a diluent. The BTF-LHCE system exhibits unique solvation structure and interfacial chemistry, leading to high Coulombic efficiency (CE) for both Si and metallic Li anodes. The Si||NCM622 and Li||NCM622 pouch cell assembled with BTF-LHCE show high cell-level specific energy densities, indicating the promising potential of the advanced ether-based electrolytes for high-voltage and high-specific-energy battery technologies.
