N2 - As known previously that carbon coating and elemental doping on the electrode are able to increase battery's performance. In this case, some studies are necessary to confirm the quality of lithium iron phosphate, LiFePO4, as a cathode material on lithium-ion batteries (LIB). Here we report the study of functional group, morphology, and magnetism of LiFePO4 by silicon doping at P site as much as 6% and carbon coating (henceforth called as LFP-Si) as a preliminary investigation to know the properties of LiFePO4 after elemental doping and carbon coating. Furthermore, the oxidation state and local geometric of the material studied by Fe K-edge X-ray absorption spectroscopy (XAS) are also being investigated in this report. The mixture of oxidation state of Fe ion (Fe2+/Fe3+) is found from the analysis result on the pre-edge region.
