Lithium-ion batteries (LIBs) with zero emission are considered to be the most important energy carrier in our daily life, which are absolutely imperative devices to power mobile phones, laptops, electric vehicles (EVs), and so on. Conventionally, carbonate-based liquid electrolytes are used in lithium ion batteries, the liquid electrolytes may undergo deterioration, with consequent safety problems, related to irreversible reactions with the electrodes. These processes generally lead to the formation of dendrites, exfoliation or degradation, in particular of the anode, with a large irreversible capacity loss. So today, the study of all solid-state batteries using solid electrolyte is active. Metallic and complex hydrides may act as anode and solid electrolytes in next generation of lithium batteries. In this experiment, lithium hydride-based materials such as LiH, LiBH4, and LiAlH4 were selected as solid electrolyte materials for all-solid-state batteries. X-ray diffraction analysis (XRD), scanning electron scanning method (SEM), and Brunauer Emmett Teller (BET) were used to confirm the electrical properties of these materials according to their hydrogen storage properties. In addition, it was manufactured in the form of a half cell and evaluated the characteristics of EIS (Electrochemical Impedance Spectroscopy). |
