LR521 battery.Research on high-energy lithium battery materials has made progress

release time:2023-10-26 Hits: Popular:AG11 battery

Recently, Cao Anmin's research group at the Institute of Chemistry, Chinese Academy of Sciences has made progress in the structure control and stability improvement of electrode materials. They have proposed a mechanism to improve the stability of electrode materials based on limited phase change with surface nanometer precision. In order to obtain both high-performance Key electrode materials with high capacity and high stability provide new means. According to the researchers, this mechanism is based on a controllable surface high-temperature solid-phase reaction. Zinc ions are introduced to promote the transformation of the surface spinel structure of lithium nickel manganate into a composite configuration of a rock-salt-like phase and a layered phase, and the two phases can be precisely controlled. The ratio improves the structural stability of the material without sacrificing the electrochemical activity of the material. This special surface phase control mechanism can overcome the damage to charge transmission caused by conventional surface inert coating methods, and provides a new way to obtain key electrode materials with high capacity and high stability based on the control of the surface chemical properties of the electrode material itself. means and mechanisms. Previously, the research group has carried out a series of work on the structure control and stability improvement of electrode materials. Based on multi-level surface interface structure design, surface lattice control and other methods, it has achieved effective control of material surface interface activity and obtained electrode materials. The stability and long cycle performance of the device are significantly improved.
