What is an Ultracapacitor?
What is an ultracapacitor? First and foremost, ultracapacitors are a type of capacitor. A capacitor is an electronic unit that releases an electric charge to power something. Capacitors are designed with varying power levels and can be composed of any of a wide assortment of materials, including glass, ceramics, metal film, and aerogel. Today, virtually all electronics use a capacitor of one type or another. An ultracapacitor is a capacitor with remarkably high power and energy density, giving them much higher efficiency. Ultracapacitors can also be described as mechanical batteries, due to their similarities to chemical batteries, and are very small in size (they are approximately the same size as traditional chemical batteries). Recently, ultracapacitors have stepped up to the forefront of the capacitor field because of their high capacitance and their multiple advantages over traditional capacitors and batteries. The substantial ultracapacitor advancements that have been made within
