WebJun 22, 2024 · In this study, we propose a design strategy for electrolytes that enable anode-free Li metal batteries with single-solvent single-salt formations at standard concentrations. Rational incorporation of –CF 2 – units yields fluorinated 1,4-dimethoxylbutane as the electrolyte solvent. WebHowever, this type of battery using conventional ether electrolytes suffers from a short lifespan, resulting from poor anode stability and severe polysulfide shuttle effects. To tackle these challenges, here we report a fluorinated ether electrolyte to boost the performance of lithiated Si–S batteries.
