Organic-inorganic metal halides are emerging as a next generation novel material in energy and optoelectronic applications. With recent updates,these materials are also showing fascinating results in other appealing fields like energy storage and sensors. Among the various examples of materials, ionic liquids based metal-halideshave also gained tremendous attention in those applications. Due to the lowmelting point (in generalbelow 100 °C) and low vapor pressure, these materials have been extensively thought for usingas an electrolyte in fuel cells, supercapacitors etc. In this presentation, I will talk about organic-inorganic transition metal-halide structures, where ionic liquids act as organic cations. These organic-inorganic metal-halides form 1D anisotropic structures which show a high ionic conductivity of 10 -4 Scm -1 at room temperature. With elevation of temperature the conductivity increases and it reaches to 10 -2 Scm -1 at 70 0 C. This is the very first report of superior ion conductivity of a transparent organic- inorganic metal-halide structure that could be a very important milestone for future solid-state battery research.
