Activated Carbon for Supercapacitor
Using starch as precursor, activated carbon for supercapacitor is prepared through 9 steps. Among which, crosslinking, catalytic activation at high temperature and totally purification are the three key technologies.
Advantages
Three advantages of this technology: (1) using starch as raw material, so the morphology and physicochemical parameters are easy to control; (2) advanced technology is employed in crosslinking, carbonization and activation, which ensures the stability of quality for the different batch products; (3) the waste gas and liquid are dealt with further post processing without pollutant.

Preliminary Application
This technology has been applied in supercapacitors.
Economic Evaluation
The requirement of supercapacitor in China will reach to 21.5 million, about 120 million Wh. If the energy density of activated carbon for supercapacitor is 5 Wh/kg, 10,000 tons per year of activated carbon will be needed, which brings 6-8 billion RMB output value.
