What is the specific power of a supercapacitor?

For example, while Li-ion batteries have a specific power of 1 - 3 kW/kg, the specific power of a typical supercapacitor is around 10 kW/kg. This property is especially important in applications that require quick bursts of energy to be released from the storage device.

How does a supercapacitor work?

Supercapacitor construction leverages highly porous carbon materials to form electrodes that store electric charge electrostatically on its surface area. The electrode material offers a surface area of up to 3000 m2/g, which gives supercapacitors much higher energy density than that of traditions capacitors. Can supercapacitors handle high current?

What is the construction of a supercapacitor?

The construction of a supercapacitor is similar to that of a battery, with some key differences. Like a battery, it consists of porous electrodes with a high surface area and a separator. However, unlike a battery, the electrodes in a supercapacitor are chemically symmetrical.

What is the maximum capacitance a supercapacitor can provide?

The maximum capacitance that these capacitors can provide is 1 Farad. If the higher capacitance is required, the capacitors will need to be quite large, which may or may not fit into typical electronic circuits. Enter the supercapacitor.
