New high performance capacitor created

    Physicists from the University of North Carolina have developed a new improved capacitor that can store a huge amount of energy, seven times higher than that of conventional capacitors.

    A capacitor is a device for storing and saving energy. Unlike a battery, a capacitor is capable of releasing energy at tremendous speed. The amount of energy that a capacitor can store depends on a non-conductive material placed between two metal surfaces. This material is called dielectric.

    In a new capacitor developed by American physicists, a bunch of two materials: PVDF and CTFE polymers was used as a dielectric. The first of them - PVDF - has long interested physicists in the quality of dielectric. But due to its slow charging, the use of only PVDF in capacitors was not very promising. The use of two polymers at once made it possible to store and release an unprecedented amount of energy. In the future, such capacitors can be used to increase the power of hybrid cars and electric vehicles, improved steering control of rockets and spacecraft, create advanced lasers, etc.
