Polytetrafluoroethylene commonly known as Teflon, is a perfluorinated ethylene polymer prized for its chemical inertness and thermal stability, decomposing only above 260 °C. In battery fabrication, PTFE serves as an advanced binder for solvent-free dry electrode processing. Under high shear, it forms nano-fibrils that create a fibrous network, preserving electrode integrity during cycling. As little as 0.5 wt% PTFE binder delivers 97% capacity retention after 200 cycles at C/3. In aqueous zinc-ion batteries, its hydrophobicity facilitates zinc-ion desolvation, while in oxygen evolution reactions, PTFE enhances electrochemical active sites, mass transfer, and long-term electrode stability.
