Abstract
In this paper, we synthesized LiMnO2 compounds doped with different amount of Ni by coprecipitation. The composition of the sample can be determined by ICP tests and energy loss spectroscopy. We found that the grain size decrease with more Ni doped .We found that the space group of the material is R-3m through XRD and Raman spectroscopy and with more Ni doped there is a blue shift in Raman spectroscopy. We can say that with more Ni doped, the material contains more Mn4 + through XPS analysis. But when Ni is doped excessively, there will be Ni3 + in the material. SEM analysis showed that corrosive effect of LiOH may have fatal effects on the electrochemical properties of the material.
