Supercapacitor and its performance enhancement via ASAC
"SCs, not batteries, would be the breakthrough for EVs"
What is a Supercapacitor?
A supercapacitor is composed of two identical electrodes and a separator dividing the two electrodes. The energy storage capacity of supercapacitors is primarily dependent on the surface areas of electrode materials. As a result, most of the commercial supercapacitor electrodes are made of high-performance activated carbons with high surface areas. These high-end activated carbons account for 80% of an electrode’s weight and 50% of it’s cost.
Supercapacitors with high power ratings (rapid charging/discharging), long cycle life (over 1 million charge/discharge cycles) and reasonable energy storage capability have been used in consumer electronics and urban power grids. Future projections indicate significant growth of supercapacitor use in electric automobiles, buses and trains, power regulators for renewable generation (solar and wind turbines), start-stop systems for automobiles.
ASAC Compared to Competitor Activated Carbon
When used in supercapacitors, ASAC out performs its competitors in not only cost, but power and energy output.
