Synthesis and Characterization of LiMnPO4/Carbon Nanocomposite Material as Cathode Material

Development of an eco-friendly, low cost and high energy density LiMnPO4 cathode material has attracted much attention due to its high operating voltage vs. Li falling within the electrochemical stability window of conventional electrolyte solutions and offers more safety features due to the presence of a strong P-O covalent bond.Synthesis of battery materials integrates the battery technology specially in development of cathode materials. Solvothermal method is used for the synthesis of In LiMnPO4 nanomaterials. The dried LiMnPO4 nanoparticles were mixed with 10 wt% conductive carbon such as acetylene black and 10 wt% polyvinylidene fluoride (PVDF) in N-methyl-2-pyrrolidone (NMP) binder for LiMnPO4/C sample. The structure of the as-prepared LiMnPO4 nanomaterial were studied by X-ray diffraction tool, morphology by scannining electron micrograph tool. The galvanostatic charge-discharge measurements of LiMnPO4/C nanostructures is undertaken.
