dc.description.abstract 将亚微米SnCux合金颗粒分布于中间相碳微球(CMS)载体表面构成的复合材料,电化学测试表明其制备的电极可逆比容量390mAhg-1,相对单纯CMS电极提高26%;第二次循环后电极充放电效率接近100%,循环30次后容量衰减率低于5%.复合材料的电化学性能受合金含量、合金颗粒与载体间的结合强度,合金颗粒在载体表面的分布均匀程度,以及合金颗粒尺寸等因素影响.该类复合材料可用作为锂离子电池中的负极.zh_CN
dc.description.abstractThe composite material were prepared by sub_micro SnCux, particles depositing on the surface of Carbonaceous Mesophase Spherules(CMS).Electrochemical cycling tests showed that coulombic efficiency of the electrodes prepared by the composite materials was near 100 % after second cycle and the capacity dropped less than 5% after the 30th cycle, versus 390 mAhg-1 special capacity, improving 26 % special capacity of pure CMS electrode. The electrochemical performance of the composite materials is depended strongly on the alloy content in the composite, the addhesive strength between alloy particles and CMS matrix, the distribution of particles on the surface of CMS and the particle size of alloy. The composite material can be applied as the anode of lithium ion batteries.zh_CN
