Selected Category:Supercapacitors

The power density (output density) of supercapacitors is the maximum electrical power that can be obtained from charged supercapacitors per unit of mass.

Tags
formula

Supercapacitors are composed of minute individual particles of activated carbon, and each of these has its own capacitance and resistance.

Tags
formula

Supercapacitors capacitance is its ability to store electric charge, and is measured in farads (F).

technicalterm

Supercapacitors have a finite lifetime. This is affected by the circumstances under which they are used, including environmental conditions such as temperature, humidity, and vibration, and electrical conditions such as applied voltage, charging, and discharging.
