High-performance supercapacitor electrode based on activated carbon fiber felt/iron oxides

Supercapacitors have received great attention in science and technology, due to its important qualities as the high cycle life, high power density, and variety of applications. The main challenge for the development of better devices is the electrode material. Developing electrode materials with high specific electrical capacitance and low electrical resistance enables an increase of energy accumulated in the supercapacitor. In addition, it is...
