Synthesis and electrochemical characterization of carbon spheres as anode material for lithium-ion battery

Carbon spheres were synthesized by the thermal decomposition of RF precursor which was synthesized by surfactant-assisted polycondensation of resorcinol with formaldehyde The morphology of precursor was preserved during the decomposition process EDS, TG, SEM, CV and galvanostatic charge-discharge methods are used to characterize the composition, morphology, and electrochemical performance of carbon spheres The results revealed that these carbon spheres had a spherical morphology, smooth surface and probable size of about 400 nm When the carbon spheres were used as anode materials for lithium-ion battery, they exhibited a high lithium storage capacity and good cycle performance. In addition, the possible progress for the preparation of carbon spheres was proposed (C) 2010 Elsevier BV All rights reserved
