💡 Novelty & Significance:
This work reveals that the position of ‐CF3 relative to the carbonyl in fluorinated ester solvents dictates solvation structure, ionic conductivity, and oxidation resistance. β-substitution (MTFP) uniquely balances high-voltage stability and fast charging, enabling Ah-level LNMO||Gr pouch cells with 78% retention at 6C and 300 stable cycles at 3C.
