Synthesis and Characterization of Metal Organic Framework UiO-66 and using in NCPEs in the Lithium Battery

In recent decades, development of Li-Battery technology is due to the transition from traditional liquid electrolytes to solid state electrolytes. In this study, a porous and stable metal organicframework (MOF) is synthesized and utilized as a filler in a nanocomposite. MOF materials, having porous structure, exhibit high surface area which gives them a variety of applications in storage of gases, catalysis, adsorption and removal of heavy metals and dyes, drug delivery andetc.These days, MOFs are extensively used in batteries and super-capacitors (1). A Nano-composite polymer electrolyte (NPCE) is prepared via cast-solution method by which MOF (Zr- BDC, UiO-66) and LiTFSI are used as fillers for PMMA polymer matrix. Thesepolymer electrolytes react well in electrochemical reactions and MOF will increase the ionic conductivity of the nano-composite electrolyte therefore the charge/discharge efficiency will beenhanced. To identify MOF and nanocomposite of PXRD, SEM and dynamic light scattering (DLS) measurements. Thermo gravimetric analysis (TGA), FT-IR, The surface areas were determined by N2 sorption measurements and calculated with the BET model (2).
