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. Hence, the proposed electrode material shows promise in its potential application in supercapacitors.
Despite their benefits, supercapacitors have several problems that prevent them from being widely utilized. Their reduced energy density in comparison to batteries is one of the primary problems. Supercapacitors usually have an energy density of 5–10 Wh/kg, which limits their use in applications that need long-term energy storage.
The development of supercapacitor materials is crucial to advance their performance and multifunctionality. Supercapacitors have been shown to possess higher energy densities than conventional capacitors and higher power densities than batteries. Advancements in electrochemical supercapacitor cells are heavily sought after.
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.
