“…As shown in Fig. 7b, for sample TAC 600-4 , when the scan rate increases from 5 to 200 mV s −1 , it can still maintain the rectangular shape, indicating that the material has excellent electrical double layer capacitance characteristics [46]. To further analyze the performance of TACs as supercapacitor electrodes, the GCD analysis was performed with 1 A g −1 under the 3E system.…”

The development and utilization of biomass and agroforestry processing byproducts for high-value applications have been an important topic in the field of renewable materials research. Based on this, a two-step microwave hydrothermal pre-carbonization and KOH activation method was proposed to synthesize tannin-based activated carbons with a high specific surface area, hierarchical pore structure, and good electrochemical performance. The microstructure, texture properties, and physicochemical characteristics were investigated. The results show that the prepared tannin-based activated carbons presented a hierarchical pore structure (micro-and mesopores) with a specific surface area as high as 997.46 m 3 g −1 . The electrochemical analysis shows that the tannin-based activated carbons have good wettability and charge transfer rates. Under the three-electrode system with 6 M KOH as the electrolyte, the active material TAC 600-4 had a maximum specific capacitance of 171 F g −1 at 0.5 A g −1 . As the current density increases to 10 A g −1 , the specific capacitance can still be maintained at 149 F g −1 , indicating a good rate capability. Therefore, the specific surface area and pore size of tannin-based activated carbons can be effectively adjusted by the alkali/carbon ratio, making it a promising supercapacitor electrode material and providing a new method for the high-value development of tannins in the field of electrochemical energy storage.

Agricultural residues are the most available biomass resources in the world and can be exploited to produce various activated carbons at low cost. The textural properties of activated carbon, including surface area, pore size, pore size distribution, and certain surface functionalities are the main factors in the application of bio‐based electrode materials for energy storage devices and electrochemical catalyst for CO2 reduction reactions, gas adsorption and separation, in water and wastewater treatment. This paper reviews the physical characteristics of activated carbons produced from various biomass resources using different methods. The effects of different activation methods, sources of biomass, and other parameters on the surface properties such as specific surface area and pore volume of activated carbon are discussed. The differences in the characteristics of activated carbon made from different agricultural biomass resources under the same parameters are evaluated. Eventually, the application of abundant agricultural residues for fabricating supercapacitors' electrode materials is also discussed.
