context: Mg-doped P2-NMM10 and Zn-doped P2-NMZ10 cathode materials are synthesized by a solid state method, whose P2-type layered structures are confirmed by X-ray diffraction (XRD) (Fig. S1† and a summary of the crystallographic data is given in Tables S1–S4†). Their compositions are verified by energy dispersive X-ray spectroscopy (EDS) (Fig. S2†), showing that all the dopants are successfully introduced into the bulk materials and uniformly distributed.
answer: Mg-doped P2-NMM10 and Zn-doped P2-NMZ10
