While the pseudo-supercapacitor is a promising emerging alternative to LIBs, it also has drawbacks. Due to the pseudo-supercapacitor having a lower energy density than LIB's, its practical use in the industrial setting diminishes. The low energy density makes it impractical to use daily as it provides a spontaneous burst of energy rather than a constant flow. This means the pseudo-supercapacitor is excellent for providing energy but not for long-term application and use, which remains its biggest hurdle. The pseudo-supercapacitor also has a large linear discharge rate, meaning that it will automatically discharge itself over a period of inactivity. 11
