Although using energy storage is never 100% efficient—some energy is always lost in converting energy and retrieving it—storage allows the flexible use of energy at different times from when it was generated. So, storage can increase system efficiency and resilience, and it can improve power quality by matching supply and demand.
The performance of an energy storage device always depends on the mechanism used by the device. The storage mechanism of a supercapacitor can be classified into three categories viz. electric double-layer capacitance, pseudocapacitance, and hybrid or battery type. Adsorption pseudocapacitance is a two-dimensional surface reversible process
