CSCC produces advanced carbon for supercapcitors (ACS), using Coal Tar Pitch as raw materials, is activated by Alkali. Its main characters are high porosity and high quality. ACS can be applied to Supercapacitors which possess high power and reliable performance in wild operation temperature. Supercapacitors can be applied in Power Support, Energy Storage, and 3C memory Backup.
ACS has high surface area and high porosity for electrolyte to improve capacity. And, low impurity in ACS can make more stability in EDLC performance.
