Considering the energy crisis, the Scientists' attention has been attracted to high-efficiency energy conversion, storage systems, and more especially electrolyte as an essential part of this field area [1]. However, some critical factors such as leakage and volatilization have limited the long-term performance and practical usage of liquid electrolytes [2]. Therefore, the quasi-solid-state electrolytes could be a suitable alternative for liquid electrolytes [3]. But, compared to liquid electrolytes, the quasi-solid-state electrolytes have less ionic conductivity [4]. Hear in, by addressing this issue, preparation of an ultra-high conductive quasi-solid-state electrolyte based on a bismuth-titanium gel composite containing lithium ions is reported. The prepared material is characterized by the use of EDX and TGA instruments to confirm the ratio of the materials. The ionic conductivity performance was measured by electrochemical impedance spectroscopy (EIS). The utilized electrochemical system was a symmetrical cell consisting of two flat graphite electrodes and as-prepared electrolytes. After optimization of the ratio amount of electrolyte materials, conductivity was achieved at 555 mS cm-1 at room temperature which hasn't been already reported [5]. In addition, this electrolyte has some other advantages such as non-flammability, environment friendly, and flexibility.
