Before we get to supercapacitors, it's worth quickly explaining what a regular capacitor is to help demonstrate what makes supercapacitors special. If you've ever looked at a computer motherboardor virtually any circuit board, you'll have seen these electronic components. A capacitor stores electricity as a static.

Customer ServiceMany articles exist in the literature that delve in detail into the differences between supercapacitors (SC) and battery cells. A non-exhaustive list of these articles includes a review from 1991 by Conway [2] and more recent articles by Simon et al. [3] and Costentin et al. [4]. As mentioned in the introduction, capacitors are composed of two electrodes separated by
Customer ServiceThere 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.
Supercapacitors are also far more durable than batteries, in particular lithium-ion batteries. While the batteries you find in phones, laptops, and electric cars start to wear out after a few hundred charge cycles, supercapacitors can be charged and emptied in excess of a million times with no degradation. The same goes for voltage delivery.
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.
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. Supercapacitors have the greatest energy density of any capacitor technology, but batteries are far superior than any capacitor in this category.
The very same control system can allow the battery to charge the supercapacitor and vice versa. Supercapacitors can be arranged in series or parallel configurations. Typically, the voltage ratings of individual capacitors fall in the 2 V to 3 V range.
Besides leveraging a non-faradaic process for charge storage and electron transfer, individual supercapacitors also operate in a lower voltage window, allowing for an even slower decomposition of the electrode and electrolyte. As shown in Figure 2, the energy density of fuel cells and batteries exceeds supercapacitors.
