摘要Black wolfberry branches are used as raw materials, and the KOH activation method is adopted for producing activated carbons with a high specific surface area. The characterization of the material reveals that with increasing activation temperatures, the specific surface area (SSA) and interconnected microporous/mesoporous structure are augmented. The SSA of the prepared material reaches 2046.07m(2) g(-1) and a high pore volume of 0.7cm(3) g(-1) is obtained. Furthermore, the prepared material exhibits excellent electrical performance. As an electrode material, the specific capacitance is as high as 355.7F g(-1). at a current density of 1 A g(-1), and the capacitance loss rate is 6.4% after 5000 cycles of charging and discharging at a current density of 2 A g(-1). These findings indicate that the wolfberry branch is a kind of biomass material, especially suitable for the preparation of super-activated carbon.
