What is Activated Carbon?

Activated carbon is a processed form of carbon with small, low-volume pores that increase surface area for adsorption or chemical reactions. It is widely used in water purification, air filtration, and as a catalyst support.

Key Findings

  • The activated carbon derived from coconut husks shows promise for high-performance super capacitors due to its availability and low cost.
  • Prototype supercapacitors using this material are four times more efficient than existing ones.
Understanding Supercapacitor:

A supercapacitor, or ultracapacitor, is an electrochemical charge storage device that offers high-power density, long durability, and ultrafast charging capabilities, outperforming conventional capacitors and lithium-ion batteries. It comprises electrodes, electrolytes, separators, and current collectors.

Advantages:

  • High-power density
  • Long durability
  • Ultrafast charging capabilities

Components:

  • Electrode
  • Electrolyte
  • Separator
  • Current collector
