High-Performance Nanostructured Supercapacitor on an Engineered Nonwoven
Abstract
The goal of this research was to investigate the feasibility of engineered nonwovens for forming supercapacitor electrode scaffolds. A further objective was to develop and demonstrate a scalable method for coating a nonwoven with conductive carbon nanotubes (CNT) and an active redox species such as MnO2. CNT provide the low electrical resistivity required of an electrode conductive pathway, as well as increased surface roughness. Surface-adsorbed MnO2 contributes to energy storage when it undergoes reversible reduction from Mn(IV) to Mn(III). Based on recently reported studies of CNT/MnO2 electrodes, a specific pseudocapacitance greater than 1,000 F/g (based on the mass of MnO2) was sought.
