Recent applications of ionic liquids in quasi-solid-state lithium metal batteries

Quasi-solid-state lithium metal batteries are considered as one of the most promising energy storage devices, and application ionic liquids (ILs) a new generation functionalized electrolyte components in has become research focuses. In this review, very recent work related to using ILs develop quasi-solid-state electrolytes their influences on performances were surveyed summarized, suggesting that introduction can improve conductivity, broaden electrochemical stability window, enhance selected electrolytes. Moreover, prepare high-performance electrodes with unique microstructures uniform distribution fillers also introduced. The composite suggested mainstream future due combination advantages inorganic polymer electrolytes, development challenges high safety discussed.
