摘　　要：与锂元素相比,钠元素在地壳中储量丰富、分布均匀又价格低廉,继锂离子电池研究受限后,钠离子电池又重新引起了研究者们的关注。在众多钠离子电池电极材料中,锡基金属氧化物因具有较高的理论比容量(1378 mA-h/g),近年来备受青睐。据文献可知,不同纳米结构的锡基氧化物材料表现出不同的电化学性能。本文从钠离子电池锡基金属氧化物亟待解决的问题出发,系统地总结了特殊形貌的锡基金属氧化物、低维度纳米结构的锡基氧化物材料的复合化、三维结构的锡基氧化物材料复合化、核壳结构的锡基氧化物材料的复合化、特殊结构的锡基氧化物材料的复合化的纳米结构特征及其电化学性能,并展望了锡基氧化物材料的面临的挑战。Compared with lithium,sodium is abundant,distributed uniformly and cheap in the crust.Following the limitation of research on lithium-ion batteries,sodium-ion batteries have attracted renewed attention of researchers.Among many electrode materials for sodium ion batteries,tinbased metal oxides have attracted much attention in recent years due to their high theoretical specific capacity(1378 mA-h/g).According to the literature,tin-based oxide materials with different nanostructures exhibit different electrochemical properties.In this paper,starting from the problem that the tin-based metal oxide of sodium ion battery needs to be solved,this paper systematically summarized the nanostructure characteristics and electrochemical properties of tin-based oxides,including tin-based metal oxides with special morphology,tin-based oxide materials with lowdimensional nanostructures,tin-based oxide material composites with three-dimensional structure,and tin-based oxide materials with core-shell structures,composite of tin-based oxide materials with special structure and the challenges faced by tin-based oxides are prospected.
