What are ultracapacitors?

Ultracapacitor is a new way of storing electricity that in the near future of the chemical battery eclipse. Instead of electrochemical storage of energy, it stores it in an electric field. Ultracapacitors have more advantages over conventional batteries, including lifelong life for more than 10 years, resistance to changes in temperature, shock, overcharging and efficiency. They require less maintenance than conventional batteries and are light light when they are destroyed because they lack toxic chemicals. They are popular for “bridging” applications in which backup power kicks as primary systems, and creates energy -available energy schemes. Because they cannot be overcrowded, ultracapacitors are ideal for returning energy from things like braking. And they can recharge in just minutes. The only disadvantage of ultracapacitors is that it must be larger than the battery to share the same charge.

Thanks to the recent progress on Mit it will soon change. The amount of charge that can hold the ultra -capacitor per unit of weight is proportional to the inner surface surface. Most ultracapacitors use porous carbon charge. However, this carbon is not perfectly porous on the atomic scale, where it has a obviously robust structure. Scientists have shown that using carbon nanotubes nets, which are only a few atoms wide, but tens of thousands of atoms, can be created structures to maximize surface surfaces that allow compressing the battery volume up to 25 times. Ultracapacitors filled with nanotubes have the potential to overcome conventional batteries in various energy storage applications.

Ultracapacitors, if expanded, would mean the first serious deviation from the conventional paradigm of electrochemical batteries since they were invented by the volt more than 200 years ago.
