3D-interconnected framework binary composite based on polypyrrole/textile polyacrylonitrile-derived activated carbon fiber felt as supercapacitor electrode

Supercapacitors have been studied due to their promising as powerful storage devices. The development of highly efficient electrodes is one way to manufacture supercapacitors with high energy and power efficiencies. Binary composites based on activated carbon fiber felt (ACFF) and polypyrrole (PPy) have been investigated to increase capacitance performance. ACF, when applied as a bulk electrode has limited electric characteristics while the PPy...
