Fig. 11. TEM analyses of (a) ZNMT and (b) NMT electrodes at the end of charge. (c) Zoomed in part of the HAADF-STEM image of the ZNMT material P3–O1 intergrowths (left) and the presence of migrated TM ions in the O1 region and P3 region. (d) A diagram about the structural changes of materials with/without Zn-doping and the corresponding cycling performance. Operando XRD analysis and corresponding structural changes during the first charge process of the (e) ZNMT and (f) NMT electrodes. (a)–(f) are reprinted with permission from ref. 106.
