中文摘要: 硅(Si)作为目前理论容量最高的一种负极材料,被认为是最有前景的一种锂离子电池负极材料,但较大的体积膨胀和较差的导电性限制了其在锂离子电池当中的应用。在硅电极体系中,选择一种合适的粘合剂对于硅电极的机械完整性和电子完整性起着至关重要的作用。总结了硅负极材料的容量衰减机理,介绍了粘合剂结构的不同对硅电极性能的影响以及新型的导电粘合剂在硅电极方面的应用。
中文关键词: 硅电极  容量衰减  结构  粘合剂  锂离子电池
Abstract:As the anode material with the highest theoretical capacity,silicon is considered to be the most promising anode material for lithium ion batteries.However,drastic volume variation and low conductivity limit the use of silicon in lithium ion batteries.In the silicon electrode system,the choice of a suitable binder plays a crucial role in the mechanical integrity and electronic integrity of the silicon electrode.The capacity decay mechanism of silicon anode materials is described,and the effects of different structure of the binders on the silicon electrode and the application of new conductive binders in silicon electrodes are introduced.
