Why do supercapacitors cost so much?
Another major challenge associated with the cost of supercapacitors is the materials employed to prepare the cathodes to make supercapacitors economically viable energy storage options. Many of the materials used in supercapacitor electrodes, such as carbon-based materials and metal oxides, are expensive, which elevates the cost.
Can a symmetric supercapacitor be used in a super capacitor?
The resulting electrode had a specific capacitance of nearly 375 F g −1 at a current density of 0.5 A g −1. Moreover, the symmetric supercapacitor had a high capacity retention of approximately 95% after 10,000 charge/discharge cycles.
