Tao shi, Associate Professor, from the School of Electronic and Information Engineering recently published the title "Insights into the Ti4+ doping in P2-type Na0.67Ni0.33Mn0.52Ti0.15O2 for enhanced performance of sodium-ion batteries" in the internationally renowned journal "Journal of Materials Science & Technology" (Area of SCI Division, Chinese Academy of Sciences, IF = 6.155) with the first author and Changshu Institute of Technology as the first completion unit. This study reported a detailed study of the enhanced rate capability and cyclic stability of the Ti-doped Na0.67Ni0.33Mn0.67O2 cathode material. The combined analysis of ex-situ X-ray absorption fine structure (XAFS) spectroscopy, aberration-corrected high resolution transmission electron microscopy (AB-HRTEM) and X-ray diffraction (XRD) show that the strong Ti–O bond in the transition metal layers stabilizes the local structure, destroy the Na+-vacancy ordering and arrest the irreversible multiphase transformation that occurs during the intercalation/deintercalation process.
