Potential electrolytes for solid state batteries and its electrochemical analysis—A review

Abstract The main purpose of this review is to present comprehensive research on all solid‐state electrolytes in a single frame. In next‐generation rechargeable solid‐state batteries, the solid‐state electrolytes are well known for their thermal stability, ionic conduction, and electrochemical stability. Therefore, in scientific societies, the development of potential solid‐state electrolytes become a trending debate to enhance their cycling stability and electrochemical properties. Here, the recent development of all solid electrolytes (such as ceramic and structure‐based electrolytes) to enhance their electrochemical properties is summarized. From previous studies, the installation of solid electrolytes is hindered by the following factors electrode‐electrolyte interface, dendrite growth, and discharge capacity as well as its solutions are discussed. Additionally, advanced electrochemical characterization techniques such as electrochemical impedance spectroscopy, cyclic voltammetry, and galvanostatic charging and discharging used to evaluate the electrochemical behavior of electrolytes in the solid frame are summarized for the first time. Moreover, an up‐to‐date article on battery performance with potential electrolytes and some future perspectives also give a vivid image of the pragmatic applications of these batteries at the commercial level.
