“Are there capacitors that can store much more energy than average?”

Let’s think about something. With the advancement of technology, new ways to store sufficient energy for machines needs to be introduced. One way we can do that is by identifying an existing concept and modifying it suit our needs. Let’s take capacitors. they’re simple, useful, and have a lot of potential for applications. One of the main bottlenecks with capacitors is that they can only store so much energy. Specifically, most capacitors are rated in Microfarads, (one farad = charge/voltage, or the ratio of charge to voltage). This means that with a certain voltage only a very tiny amount of charge can be stored (specifically, one microfarad means that it would take one million volts to store one coulomb of charge).

Now, how could we modify capacitors to store a higher density of charge? Well, as discussed earlier, the capacitance of a capacitor is proportional to the area of the plates divided by the distance between them, so what if not only we used special materials, but we also used very large plates separated at a very small distance? Scientists and  engineers have termed such an invention supercapacitors. Supercapacitors can have capacitance values usually rated in the farad level, or one million times the ratio of noraml capacitors! This means that such inventions can store much more energy than.Supercapacitors (also known as ultracapacitors) have many applications, ranging from being used as a storage medium for regenerative braking systems to Defibrillators. In fact, supercapacitors are deemed to be so practical that major that major transportation networks such as the Portland MAX are starting to use them
