Electrochemical double layer capacitor and lithium-ion capacitor based on carbon black

► Carbon black SC3 is a promising active material for Electrochemical Double Layer capacitors (EDLCs) and Lithium-ion capacitors (LIC). ► Carbon black SC3 displays a specific capacity 40 mAh g−1 and a specific capacitance of 115 F g−1. ► The value of specific capacity and capacitance of SC3 are not strongly affect at high current density. ► EDLC based on SC3 display very good cycling stability.
