摘要
综述了锂离子电池Cu6Sn5合金的研究进展。介绍了锡铜合金体系作为锂离子电池负极的优势,并指出其循环性能对比石墨负极仍然不够理想。对此,还概述了目前国内外改进锡铜合金材料循环性能的方法,主要包括实现纳米化、薄膜化以及多孔结构。
The recent advance of Cu6Sn5 alloy as a candidate cathode for Li-ion batteries was reviewed in this paper.Compared to graphite anode,the advantages as well as its unsatisfactory cycle performance were analyzed.It also summarized the main methods both at home and abroad to improve the cycle performance,including making it into nanostructure,thin-film and porous structure.
