【摘要】：钠离子电池在20世纪70年代末80年代初得到关注,但因锂离子电池优异的电化学性能而没有得到广泛研究.随着电动汽车、智能电网时代的到来,锂资源短缺将成为制约其发展的重要因素.因此,亟需发展下一代综合性能优异的储能电池体系.钠和锂具有相似的物化性质,且钠资源丰富,成本低廉,是非常有发展潜力的电池体系,近年来得到了国内外研究人员的广泛关注.简要综述了近年来钠离子电池的研究成果,就层状Nax MO2(M=Co,Ni,Fe,Mn,V等)材料、聚阴离子型材料、金属氟化物等正极材料及碳基负极材料、合金和金属氧化物等负极材料的电化学性能进行了介绍,阐述了有机体系电解质和凝胶电解质在钠离子电池中的应用,并对其存在的问题以及未来发展方向作了探讨.
[Abstract]:Sodium ion battery was paid more attention in the late 1970s and early 1980s, but it has not been widely studied because of its excellent electrochemical performance. With the arrival of electric vehicle and smart grid era, the shortage of lithium resource will be an important factor restricting its development. Therefore, it is urgent to develop the next generation energy storage battery system with excellent comprehensive performance. Sodium and lithium have similar physical and chemical properties, and sodium is rich in resources, low cost, is a very potential battery system, in recent years has been widely concerned by researchers at home and abroad. The research achievements of sodium ion batteries in recent years are briefly reviewed. The materials of layered Nax MO2O _ 2M _ (2) O _ (2) C _ (Co) / Ni _ (+) Fe _ (2) mn _ (V), polyanionic materials, metal fluoride and other cathode materials and carbon-based negative electrode materials are briefly reviewed. The electrochemical properties of anode materials such as alloys and metal oxides were introduced. The application of organic electrolytes and gel electrolytes in sodium ion batteries was reviewed. The existing problems and the future development were also discussed.
