Molecular Engineering of Polytriphenylamine: A Fluorinated Cathode for High‐Voltage, Ultrafast, and Stable Sodium‐Ion Batteries

Advanced Energy Materials, Volume 16, Issue 34, 9 September 2026.
Fluorination of polytriphenylamine lowers the HOMO energy, enabling high‐voltage operation of the PFTPA cathode. Electron‐withdrawing F substituents stabilize the nitrogen redox center and suppress polarization, leading to fast kinetics. The optimized polymer delivers ∼3.75 V vs.
