Congratulations to Dr. Chen Xin from the research group for a paper received by the international authoritative journal "Nature Communications"! The topic of the thesis is "Ether Compatible Sulfurized Polyacrylonitrile Cathode with Excellent Performance Enabled by Fast Kinetics via Se-doping".
In this article, the researchers developed a selenium-doped polyacrylonitrile sulfide cathode material, which exhibits excellent electrochemical performance in both traditional commercial lithium ion electrolytes and ether electrolytes; the catalytic amount of selenium doped The impurity increases the lithium ion diffusion coefficient and reduces the overpotential in the electrode cycle; first-principles calculations prove that selenium doping can reduce the lithium ion diffusion barrier and accelerate the reaction kinetics; the material achieves both high rate and long Cycle life.
