    Recently, the team of Chen Weimin of the School of Chemical Engineering and Pharmacy of Wuhan Institute of Technology obtained high-performance carbon anode materials
    for sodium-ion batteries by coordinating surface-induced reactions and embedded reactions.

    In the laboratory, the researchers first prepared hard carbon by carbonizing organic potassium salts at high temperature, and then activated it with nitric acid to create abundant sodium storage active sites on the carbon surface, and at the same time expand the interlayer distance of carbon to obtain a porous carbon material (ORC) rich in oxygen functional groups.
    Then, by analyzing the sodium storage properties of carbon materials and the diffusion reaction mechanism of sodium ions in solid-phase electrode materials, the synergistic mechanism of surface-induced sodium storage and embedded sodium storage was discovered, and the high rate performance and long cycle life
    of the anode material of sodium-ion batteries were achieved by coordinating the surface reaction and embedded reaction.
    The oxygen-containing functional activated carbon electrode material obtained by the above method can be fully charged in 3 minutes and has a cycle life of more than 1000 times

    The research work was also strongly supported
    by the team of Professor Huang Yunhui of the Power and Energy Storage Battery Laboratory of Huazhong University of Science and Technology.
    The current research on hard carbon anodes by the two partners mainly focuses on the construction of porous biomass carbon materials doped with heterogeneous elements through simple and "green" methods using biomass rich in natural resources as raw materials, and applying them to the research of sodium-ion batteries, so as to further reduce the preparation cost of carbon materials and improve the sodium storage performance of hard carbon anodes, and it is also of great significance
    to accelerate the promotion and application of biomass materials.
