Supercapacitive behaviors of worm-like mesoporous carbon in non-aqueous electrolyte

This paper discusses the electrochemical behaviors of worm-like mesoporous carbon obtained in 1.0 mol L −1 LiClO 4 /ethylene carbonate + dimethyl carbonate solution. The capacitance for nanoporous carbon system advances up to 147 F g −1 and a wide voltage window (2.5 V) for three electrode system wa...

Description
Summary:This paper discusses the electrochemical behaviors of worm-like mesoporous carbon obtained in 1.0 mol L −1 LiClO 4 /ethylene carbonate + dimethyl carbonate solution. The capacitance for nanoporous carbon system advances up to 147 F g −1 and a wide voltage window (2.5 V) for three electrode system was achieved. The specific energy and specific power reach as high as 127.6 Wh kg −1 and 5.0 kW kg −1 . These results show that worm-like mesoporous carbon can be used for high energy density and power density non-aqueous electrolyte supercapacitors.
