Created a new high performance capacitor

Physicists from the University of North Carolina have developed a new improved capacitor, capable of storing an enormous amount of energy, seven times higher than that of conventional capacitors.

Capacitor - a device for the accumulation and conservation of energy. Unlike a battery, a capacitor is capable of releasing energy at tremendous speed. The amount of energy that a capacitor can accumulate depends on a non-conductive material placed between two metal surfaces. This material is called dielectric.

In the new capacitor developed by American physicists, a bunch of two materials was used as a dielectric: PVDF and CTFE polymers. The first of them - PVDF - has long been interested in physicists as a dielectric. But due to its slow charging, the use of PVDF in capacitors only was not very promising. The use of two polymers at the same time 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 of rockets and spacecraft, the creation of improved lasers, etc.
