Definition - What does Nanomaterial Supercapacitor mean?
A nanomaterial supercapacitor is a capacitor that uses nanomaterial in the manufacturing of electrodes or dielectrics. Supercapacitors are widely used as an alternative to capacitors with high power and energy density, and are used in grid energy storage, electric vehicles, plug-in hybrid vehicles, power tools and mobile electronics. Supercapacitors that use nanomaterial are essentially made up of nanocomposites containing nanotubes (usually composed of carbon material).
Techopedia explains Nanomaterial Supercapacitor
Nanomaterial is a type of nano-scale material used as building blocks in the fields of physics and electronics, whereas supercapacitors are quickly replacing regular capacitors owing to their high performance and high energy concentration. A nanomaterial supercapacitor is an electrochemical electronic device (capacitor) that has the capability of increasing the surface area of storage of static electrons as the amount of energy increases; it can expand due to its structure made of nanotubes. The anodes and cathodes, like in a conventional capacitor, are separated by insulating material also known as dielectric. The overall performance of a nanomaterial supercapacitor depends upon the material being used to manufacture it and the properties of electrodes.
