The high capacity electrochemical capacitors with capacitance values much higher than the other capacitors, are called as Super Capacitors. These can be categorized as a group that lies between electrolytic capacitors and rechargeable batteries. These are also called as Ultra Capacitors.
There are many advantages with these capacitors such as −
- They have high capacitance value.
- They can store and deliver charge much faster.
- They can handle more charge and discharge cycles.
These capacitors have many applications such as −
- They are used in cars, buses, trains, elevators and cranes.
- They are used in regenerative braking.
- They are used for memory backup.
The types of super capacitors are Double-layered, Pseudo and Hybrid ones.
