Today, the energy crisis and environmental pollution is a big issue and stimulated the development of clean and renewable energy storage systems. Supercapacitors (SCs) also known as ultra-capacitors or electrical double-layer capacitors, offer very high capacitance in a small package which becomes one of the rapid energy storage systems. With lower voltage limits, it acts as a bridge between rechargeable batteries and electrolytic capacitors. It acquires electric energy in the form of the electric field which amidst the two conducting plates and enables the ample charge–discharge cycles than batteries. This leads SCs to be more active in uninterruptible power supply (UPS), active filters, traction, electric, and automotive drives and so captured the attention in society. The key features of the present chapter are to explore the recent developments and types of SCs, present the structure of SC, include a brief overview of the process of charging and discharging, and discuss the impact on the performance of SCs at various operating conditions.
