Mechanistic Control of Cathode–Electrolyte Interphase Formation in Gel Polymer Electrolyte for Lithium‐Ion Batteries

Angewandte Chemie, EarlyView.
To regulate a distinct degradation pathway introduced by residual monomers in in‐situ gel polymer electrolytes (GPEs), tris(4‐fluorophenyl)phosphine (TFPP) is coupled with a voltage hold (VH) protocol. TFPP first covers the high‐Ni cathode surface and then preferentially decomposes during the hold step, forming a cathode–electrolyte interphase (CEI ...
