Biomass materials are perceived as sustainable, carbon-rich precursors for the fabrication of carbon materials. In this study, we demonstrated the capacitance performance of biomass-derived carbon, produced by using golden shower tree seeds (GTs) as carbon precursors and potassium ferrate (KFeO) as the activation agent. The as-prepared porous carbon (GTPC) possessed an ultrahigh specific surface area (1915 m g) and abundant pores. They also exhibited superior electrochemical performance, owing to their well-constructed porous structure, high surface area, and optimized porous structure. Optimized activated carbon (GTPC-1) was used to assemble a symmetric solid-state supercapacitor device with poly(vinyl alcohol) (PVA)/HSO as a solid-state gel electrolyte. The device exhibited a maximum areal energy density of 42.93 µWh cm at a power density of 520 µW cm.
生物质材料被视为用于制造碳材料的可持续、富含碳的前驱体。在本研究中，我们展示了以黄金雨树种子（GTs）为碳前驱体、高铁酸钾（KFeO）为活化剂制备的生物质衍生碳的电容性能。所制备的多孔碳（GTPC）具有超高的比表面积（1915 m²/g）和丰富的孔隙。由于其结构良好的多孔结构、高比表面积和优化的孔隙结构，它们还表现出优异的电化学性能。优化后的活性炭（GTPC-1）用于组装以聚（乙烯醇）（PVA）/HSO为固态凝胶电解质的对称固态超级电容器器件。该器件在功率密度为520 μW/cm²时表现出最大面积能量密度为42.93 μWh/cm²。
