What is the difference between a super capacitor and a battery?
There are four main differences between supercapacitors and batteries: energy density, power density, lifetime, and cost. Energy density refers to the amount of charge a technology can hold. As shown in Figure 3, capacitors have the lowest energy density of commonly used storage devices.
What makes a supercapacitor different from a battery?

What is the difference between supercapacitors and regular capacitors?
Supercapacitors are also known as ultracapacitors or double-layer capacitors. The key difference between supercapacitors and regular capacitors is capacitance. That just means that supercapacitors can store a much larger electric field than regular capacitors. In this diagram, you can see another major difference when it comes to supercapacitors.
Are supercapacitors cheaper than batteries?
Supercapacitors have a much higher up-front cost than batteries, which causes many designs to use batteries instead. Given the differences in lifetime of supercapacitors and batteries, the long-term cost of supercapacitors may be a cheaper option even with the higher initial cost.
Are supercapacitors better than lithium ion batteries?
The biggest drawback compared to lithium-ion batteries is that supercapacitors can't discharge their stored power as slowly as a lithium-ion battery, which makes it unsuitable for applications where a device has to go long periods of time without charging.
