Graphitic degree
WebThe graphitic degree of lignin-derived CNSs was investigated by Raman spectroscopy (Fig. 4a). The CNSs prepared from 5, 10 and 20 mg mL 1 lignin aqueous dispersions are abbreviated as LC-05, LC-10 and LC-20, respectively. The Raman spectra of all the three CNS samples show two peaks associated with D band ( 11360 cm ) and G band ( 1600 … WebMoreover, progress on the applications of biomass-derived carbon materials as electrodes for energy storage devices is summarized, including electrochemical capacitors, lithium-sulfur batteries, lithium-ion batteries, and sodium-ion batteries. The effects of the pore structure, surface properties, and graphitic degree on the electrochemical ...
