Because of high energy capacity of rechargeable Lithium-ion batteries (LIBs) LIBs are widely used in various applications such as electric vehicles, portable devices, and electric grids. Recent demand of energy storage devices requires not only their performance but also their stability, resulting in significant increase in related research including development of solid-state electrolytes. Currently, commercialized electrolytes in LIBs are volatile and flammable organic carbonate-based liquids, which can occur serious safety hazards, including fire, explosion, and leakage in harsh conditions. In this work, we used Ionic-liquid electrolytes, one of the most promising candidates to replace organic electrolytes for LIBs because of its non-flammability and non-volatilility, to improve the stability of the LIBs.
