LiFePO 4 is considered the most environmentally friendly, inexpensive, abundant, has good cycle stability and thermal stability. However, LiFePO 4 has the main disadvantage of potential voltage and conductivity which is relatively lower than other batteries. This can be overcome by adding carbon and reducing particle size. The method used in this research is the rheological phase method. This method was chosen because the material used is easy to obtain and the price is cheap, no requires a lot of tools, and good homogeneity. LiFePO4 is very sensitive to direct air. So in this study an evaluation of the effect of argon gas, hydrogen, and nitrogen on the material. LiFePO 4 analyzed its morphology with SEM (Scanning Electron Microscopy), its crystallinity with XRD (X-Ray Diffraction) and functional group of LiFePO 4 with FTIR (Furier Transformation Infra-Red). Based on the characterization result, the optimum synthesis product continued battery performance test. LiFePO 4 H 2 -Ar produces the best battery capacity compared to other gases because it uses reducing gas which can increase the carbon content of the material.
