Abstract: Activated woodceramics for electrode materials have been prepared from the carbonized materials of lignin extracted from black liquor with FeC6H5O7 as catalyst at 1 200 ℃ for 2 h and with KOH as activation agent at 800 ℃ for 1.5 hours. The phase composition, specific surface area, pore structure and electrochemical properties of as-prepared woodceramics were performed by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), transmission electron microscopy (TEM), N2 adsorption-desorption (BET), constant current charge and discharge, and cyclic voltammetry respectively. The results show that when the ratio of ferric citrate to lignin is 1∶1, the activated lignin-based woodceramics have good graphitization characteristics, and its specific surface area can reach 712.59 m2/g, and the pore size is mainly distributed at 1.64 nm. The specific electrode capacitance of the electrode materials prepared in the inorganic system (6 mol/L KOH) can reach 115.6 F/g. After 2 500 cycles of charge and discharge, the specific capacitance retention rate reaches 75.2%, exhibiting good electrochemical performance and having the potential as an electrode material for an ideal electrochemical capacitor.
