摘要: 应用机械合金退火法合成Mg2S i及MnS i材料,并由机械球磨法制备系列Mg2S i/C复合材料.电化学性能研究表明:以硅化物与碳材料复合,即可明显提高原纯硅化物材料的可逆比容量及其循环稳定性,而球磨复合法则是实现硅化物材料复合的一种简单且有效方法.

Abstract: The anode materials of Mg_(2)Si and MnSi were synthesized by mechanically activated annealing(MAA) techniques in this work and the in electrochemical performances were also studied.A series of composite materials of Mg_(2)Si and CNTs or CMS were prepared by ball-milling method respectively.The reversible capacities of the composites were higher than that of the pure Mg_(2)Si and pure carbon materials.The cyclic performances have been improved greatly by ball-milling of the Mg_(2)Si and carbon materials.Results show that ball-milling method is one kind of method to make alloy materials into practical use.

Key words: Li-ion battery, Composite materials, Mg_(2)Si, MnSi, Carbon materials
