Novel structural supercapacitors based woven carbon fiber (WCF) have to develop employing vacuum assisted resin transfer molding (VARTM) process. The growth of nanowires on WCF is an efficient process and can be used in structural capacitors which can trigger the electric vehicle industries toward a new direction. The specific surface area of the carbon fiber will be enhanced by base etching and by growing metal oxide nanowires on the surface of the WCF. The usage of ionic liquid and cationic salt will enhance the capacitance. The energy and power densities will also be measured. This study could be exploited in diverse applications such as electric cars, unmanned aerial vehicles (UAVs), and portable electronic devices.
