Demethylation of Fluorine-Free Ethers to Reconcile Li <sup>+</sup> Transport Kinetics and Oxidation Stability
pouch cell with the formulated electrolyte retains 85.14% capacity at 1C (1000 cycles) under room temperature and 80.31% at 0.2C (200 cycles) under -20 °C. Our demethylation strategy expands molecular design principles of electrolyte solvents, advancing the development of robust lithium-ion batteries capable of operating under extreme conditions.
