摘要: An efficient synthesis method, namely dielectric barrier discharge plasma assisted milling (P-milling), is used for the first time to prepare Sn–C anode materials lithium ion batteries. By short-time P-milling, a unique nanocomposite obtained with microstructure of multi-scale Sn particles homogeneously dispersed in graphite matrix. The P-milled anodes exhibit much better electrochemical performance higher reversible capacity and cyclability comparison those by conventional (C-milling). Our results demonstrate that simple method composite on large scale good battery applications.
