N-activated carbon fiber produced by oxidation process design and its application as supercapacitor electrode

There are three basic steps to activated carbon fibers (ACF) manufacturing, from PAN fiber: oxidation/stabilization, carbonization and activation. Carbon material, specially ACF is a very attractive material to be used as supercapacitor electrode. The literature describes carbon material surface chemistry importance for supercapacitors application, mainly nitrogen groups by N-doping. Oxidation/stabilization is an important non-explored factor...
