Synthesis and characterization of pyrolyzed sugar carbons under nitrogen or argon atmospheres as anode materials for lithium-ion batteries

The pyrolysis of local white sugar was studied at various heat-treatment temperatures in nitrogen and argon atmospheres. The pyrolyzed sugar carbons (PSCs) were characterized by TGA, XRD, SEM, Raman, elemental, and BET surface area analyses. The effects of atmosphere and heat-treatment temperature on the structure, morphology, and cell performance are discussed.
