Aromatic carbon coated tin composites(A/Sn) have been prepared by thermal decomposition of the stannous 1,8-naphthalenedicarboxylate precursors,which is a reformative preparation method.Sugar carbon coated tin composites(S/Sn) also are prepared as a contrast with the A/Sn composites.The morphology and composition of the products were characterized by Scanning Electricity Microscopy(SEM) and X-Ray Diffraction(XRD).Their electrochemical performance as anode materials for lithium ion batteries were investigated;the results indicated that these materials exhibited good performance,and the cycle stability of A/Sn composites is especially superior to the S/Sn composites due to its special carbon resource.
