Application

Activated carbon is used as anode in rechargeable batteries due to its many advantageous properties such as a very low insertion/deinsertion potential, large surface area, high pore density, good conductivity, low cost, and good mechanical and chemical stability compared to other alternatives. Experimentally it has been observed that by using activated carbon electrode, the diffusion co-efficient of potassium ion in potassium ion batteries improved by 7 times and could deliver a a high reversible capacity of 100 mAh/g after 100 cycles (at a high current density of 0.2 A/g), and exhibits increased rate performance. In addition, owing to the typical characteristic of porous structure, activated carbon (AC) is widely used for supercapacitor electrode and also possesses the potential as anode material in lithium ions batteries (LIBs).
