According to a report in the journal of science and technology, ion battery application is more and more close to the life of the people, but lithium resources on the earth is very limited, and high mining cost. To develop a replacement battery became the various countries' scientists trying to important direction. Nanjing university of technology professor Xia Hui and team cooperation both at home and abroad, the first structure design and control methods of important progress in manganese anode material research, the low cost of sodium ion batteries is expected to replace the lithium ion battery, relevant results published in the latest issue of nature & middot; Letters.
sodium rich in resources, mining cost is only one percent of the lithium and sodium ion battery research and development for scientific research personnel & other; Clearing & throughout; The field. And layered structure of the manganese acid sodium anode material has high theoretical capacity, low cost and advantages of sources, and make it become a hot research of sodium ion battery cathode material object.
but due to the narrow layer spacing of manganese acid sodium anode materials, charge and discharge process, the radius is larger the sodium ion in the interlayer of migration, will & other; Crushing & throughout; The structure of the anode material, become the key difficulty of sodium ion battery research and development. In addition to the layer spacing, another important factor influencing the performances of sodium ion battery for sodium ion content of layered structure. Many researchers attempt was prepared by various methods in different layers of manganese acid sodium, but I can't meet the demand of practical application of performance indicators.
