A few days ago, the reporter learned from Harbin Institute of Technology that the energy conversion materials team led by Prof. Chen Gang of the School of Chemical Engineering and Chemistry of the HIT University has made important progress in the research of anode materials for lithium-ion batteries. The research results were published in the top journal of the international field of materials science, "Advanced Materials," the 46th issue on December 13, 2017, and was selected as the cover article. In recent years, due to its high energy density, long cycle life, and environmental friendliness, lithium-ion batteries have gradually become the mainstream power source for portable electronic devices, and are considered to be most applicable to the drive devices of electric vehicles and hybrid electric vehicles. The power of the foreground. At present, in many fields, the demand for lithium ion batteries is increasing day by day. The capacity of traditional electrode materials and the rapid charge and discharge capability have reached a bottleneck. It is imminent to develop electrode materials with high rate performance to meet efficient and rapid energy storage and output. Chen Gang's team took the lead in proposing the introduction of two-dimensional nanofluidic structures into cobalt oxide anode materials to improve the material's rate performance. The team prepared nano-sheets modified with anionic groups on the surface by a simple sol-gel method. These modified groups promoted the assembly of nano-sheets into a stack of layers that can be self-supporting. The spacing of the nanosheets is slightly less than twice the Debye length of lithium ions and can provide two-dimensional fluidic channels for lithium ion transport. The negative wall of the channel wall will selectively attract lithium ions, repel negative ions, and accelerate lithium ion transport. Through electrochemical tests, it was found that the ionic conductivity of the fluid channel nanosheets was increased by several orders of magnitude compared to the bulk materials, and the battery's rate performance was greatly improved. The research work indicates a new direction for effectively improving the rate capability of the electrode material, and provides a new exploration idea for constructing a high-power, high-stability lithium ion battery. The research work was supported by the cooperation of the National Natural Science Foundation of China and Professor Yu Guihua of the University of Texas at Austin.
