Abstract
Biomass-derived porous carbon materials are widely used as electrode materials for supercapacitors due to their low cost, wide availability, rich pore structures, and good stability. Different biomass-derived porous carbon materials have variations in compositions and structures, resulting in different electrochemical performances. Here, four types of biomass-derived porous carbon materials, namely corn stalk-derived porous carbon (CC), bamboo-derived porous carbon, peanut shell-derived porous carbon and rice straw-derived porous carbon, were prepared using raw materials such as corn stalk powders, bamboo powders, peanut shell powders and rice straw powders, respectively. The preparation process was carried out through high-temperature carbonization and activation methods. The prepared carbon electrode samples were characterized by XRD, Raman, SEM and BET, and the three-electrode performances and the assembled symmetric supercapacitors were also investigated by a series of electrochemical testing techniques. The results indicate that among the four biomass-derived porous carbon materials, CC exhibits the best electrochemical performances, and the specific capacitance is 103 F g−1 at a current density of 0.1 A g−1. The assembled symmetric supercapacitors demonstrate a specific capacitance of 99 F g−1 at a current density of 0.1 A g−1, a specific mass power density of 25 W kg−1 and a specific mass-energy density of 3.44 Wh kg−1. After 20,000 cycles, the capacitance retention rate remains at 104%, which shows an increase. Therefore, the electrode samples prepared from corn stalk-derived porous carbon exhibit high specific energy, high specific power and long cycle life and have promising prospects for development in supercapacitors.
生物质多孔碳材料因其成本低、来源广、孔隙结构丰富和稳定性好而被广泛用作超级电容器的电极材料。不同的生物质衍生多孔碳材料在成分和结构上存在差异,因而具有不同的电化学性能。本文分别以玉米秆粉末、竹子粉末、花生壳粉末和稻草粉末为原料,制备了四种生物质衍生多孔碳材料,即玉米秆衍生多孔碳(CC)、竹子衍生多孔碳、花生壳衍生多孔碳和稻草衍生多孔碳。制备过程采用高温碳化和活化方法。对制备的碳电极样品进行了 XRD、拉曼、扫描电镜和 BET 表征,并通过一系列电化学测试技术研究了三电极性能和组装的对称超级电容器。结果表明,在四种生物质衍生多孔碳材料中,CC 的电化学性能最好,在电流密度为 0.1 A g-1 时的比电容为 103 F g-1。组装好的对称超级电容器在电流密度为 0.1 A g-1 时的比电容为 99 F g-1,比质量功率密度为 25 W kg-1,比质量能量密度为 3.44 Wh kg-1。经过 20,000 次循环后,电容保持率仍为 104%,表明电容保持率有所提高。因此,由玉米秆衍生的多孔碳制备的电极样品具有高比能量、高比功率和长循环寿命的特点,在超级电容器领域具有广阔的发展前景。
