In recent decades, development of Li-Battery technology is due to the transition from traditional liquid electrolytes to solid state electrolytes [1]. In this study, a porous and stable metal organic framework (MOF) is synthesized and utilized as a filler of a nanocomposite. The metal-organic frameworks are widely used in batteries attribute to their huge surface area, high porosity, low density, controllable structure and tunable pore size that can favor the electrochemical reaction, interfacial charge transport, and provide short diffusion paths for ions [2]. MOFs 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 and etc. These days, MOFs are extensively used in batteries and super-capacitors [3].

A Nano-composite polymer electrolyte (NCPE) is prepared via cast-solution method by which Zr-BTC MOF, benzene-1,3,5-tricarboxylic acid (H3BTC), and lithium bis(trifluoromethanesulfonyl) imide (LiTFSI) are used as fillers for poly methyl metacrylate (PMMA) matrices. These polymer electrolytes react well in electrochemical reactions and MOF will increase the ionic conductivity of the nano-composite electrolyte. Therefore, the charge/discharge efficiency will be enhanced [4].
