纳米SnO_2作为锂离子电池负极材料的研究进展

Research progress of nano SnO_2 in cathode electrode material for lithium ion battery

作为高比容量的锂离子电池负极材料,纳米SnO_2材料主要集中在形貌结构与电化学性能内在关系的研究。概述了低维度的SnO_2纳米线、纳米棒及高维度的多孔核-壳微球、多层中空纳米花等结构形貌的生长机理、合成方法及电化学性能,并对纳米SnO_2负极材料在锂离子电池的应用进行展望。

As lithium-ion battery cathode materials with high specific capacity,the nano SnO_2 materials were mainly focused on the internal relationship of structure and electrochemical performance.The growth mechanism,synthesis methods and the electrochemical properties of the low dimensional SnO_2 nanostructure such as nanowires,nanorods and high dimensional such as core-shell microspheres,hierarchical flower-like hollow spheres structure were summarized.And these kinds of nano materials showed a good prospect for cathodes of new generation lithium ion batteries.
