摘要/Abstract

摘要：采用新兴的软化学方法合成了锡氧化物基粉末材料.用X-射线衍射、扫描电镜和电化学方法对材料的微观结构、形貌和电化学性能进行了研究.结果表明：锡氧化物基材料的颗粒的平均粒径约为200 nm，颗粒之间形成了类似中孔材料的相互连接的网状结构.这种材料的可逆充电容量超过570 mAh/g，30次循环后平均每次循环的容量衰减只有0.15%.良好的电化学性能表明锡氧化物基材料有望作为新一代锂离子电池的负极材料.

Abstract: Novel soft chemical approach was developed to synthesize tin oxide-based powders.The microstructure,morphology,and electrochemical performance of the materials were investigated by X-ray diffraction,scanning electron microscopy and electrochemical methods in detail.The particles of tin oxide-based materials form an interconnected network structure like mesoporous material.The average size of the particles is about 200 nm.The materials deliver a charge capacity of more than 570 mAh/g.The capacity loss per cycle is about 0.15% after being cycled 30 times.The good electrochemical performance indicates that tin oxide-based materials are promising cathode for lithium ion batteries.

Key words: Tin oxides, soft chemical synthesis, Lithium ion batteries, electrochemical properties
