摘要
综述了锂离子电池碳材料与锡基合金复合材料的发展现状,总结了C-Sn二元复合材料的主要种类,并分析了它们作为负极材料的电化学性能特点;同时阐述了C-Sn-金属三元复合材料的发展,这种复合材料结合了碳材料的循环稳定性和合金材料的高比容量的优势,是具有发展前景的新型锂离子电池负极材料。
The development status of carbon and tin-alloy composite anode materials is introduced. C Sn corn posite materials are classified into three categories, and the electrochemical performance characteristics for every type of composite materials are analysed. The latest progress of C-Sn-alloy composite materials, which have a higher capaci - ty and excellent cycle performance is outlined. Therefore, it is a promising anode material for Li-ion batteries in the future.
