摘要：

Considering cost and environmental protection, the harmful aquatic plant altemanthera philoxeroides derived carbon material with super high specific surface area (2895 m(2) g(-1)) is an ideal electrode material for supercapacitor. The structure and composition of these carbon materials were characterized by SEM, EDS, XPS and BET measurements. The obtained material exhibits a maximum specific capacitance of 275 F g(-1) at 0.5 A g(-1) and retains a capacitance of 210 F g(-1) even at 50 A g(-1). In addition, it also shows excellent capacity retention of 5000 cycles at 10 A g(-1). (C) 2017 Elsevier B.V. All rights reserved.
