Facile fabrication of mesoporous carbon from mixed polymer precursor of PVDF and PTFE for high-power supercapacitors

Highly porous activated carbon is an essential electrode material for high-energy-density supercapacitors, since the electrical charge is stored through electrolyte-ion adsorption on an electrode with high surface area. Here, we report the facile and simple synthesis of an activated carbon with tail...

Zusammenfassung:	Highly porous activated carbon is an essential electrode material for high-energy-density supercapacitors, since the electrical charge is stored through electrolyte-ion adsorption on an electrode with high surface area. Here, we report the facile and simple synthesis of an activated carbon with tailored porosity from the blended polymers with different thermal stabilities, i.e., polyvinylidene fluoride (PVDF) and polytetrafluoroethylene (PTFE). Through a thermal treatment (900 °C) under inert atmosphere, PVDF is simply transformed into highly microporous (
