- Abstract
Reducing the graphitization temperature with the assistance of catalysts is a useful way to save electrical energy. In this report, magnesium is employed to catalyse the graphitization of anthracite at low temperatures. To verify the role of Mg, the pyrolysis of only anthracite at the corresponding temperatures was also performed. The Mg-assisted samples showed some degree of graphitization, as confirmed by XRD, Raman spectroscopy and HRTEM. The only anthracite-derived carbons were amorphous, which confirmed the catalytic graphitization role of Mg. These samples were used as the anodes of lithium-ion batteries and potassium-ion batteries. The proportion between the amorphous and graphite parts were different in the series of samples prepared at various temperatures; thus, their performance, including the capacity, rate performance, and average voltage, varied.
