Type: article
Abstract: In this study, the urea technique was used to synthesis LiMn1-xCrxO2 powders (x = 0, 0.125, 0.25, 0.375, 0.5, 0.625, 0.75). XRD, FTIR, FE-SEM, and EDX studies were used to examine the surface morphology and crystal structure of the produced powders. Both the prepared LiMnO2 phase's XRD pattern and X-ray diffraction show that the crystal structure of the LiMnO2 phase has a hexagonal shape. When Cr is doped, a cubic LiMnO2 nanostructure forms. LiMnO2 and LiMn1-xCrxO2 FTIR spectra analysis showed a number of vibrational modes, including (C=O and O–H). According to the FE-SEM data, every sample has a nanostructure. The presence of transition metals (Mn) in LiMnO2 and transition metals (chromium and manganese) in LiMn1-xCrxO2 is shown by the EDX spectrum's dimensions.
