Results and discussion . The XRD patterns of pristine and coated samples are shown in Fig.? 1 a. The main diffraction peaks (003) and (104) of the patterns are in good agreement with the α-NaFeO 2 (R-3?m space group) 28 . There is no peak shift found in (003) reflection of the coated samples as shown in Fig.? 1 b which infers that Li 3 PO 4 is coated on the NCM surface. The XRD pattern of synthesized Li 3 PO 4 powder is compared with JCPD card # 98-005-0058 as shown in figu...
