Abstract: Composite electrolytes are provided that are useful as a solid-state electrolyte in alkali metal batteries. in particular in lithium metal batteries over a wide temperature range. In some aspects. the composite electrolyte includes an alkali metal salt of an aromatic polyimide polymer: and an ionic liquid: wherein the composite is a solid at 25° C. and at a temperature of about 200° C. For example. a molecular ionic composite electrolyte containing 10 wt % PBDT and 90 wt % 1-ethyl-3-methylimidazolium trifluoromethane-sulfonate (EMImTfO) shows an E′ of ≈0.4 GPa and an ionic conductivity of ≈ 3.2 mS cm− at room temperature. In various aspects. batteries are also provided containing a composite electrolyte described herein. The electrolytes enable batteries that are more stable and exhibit less risk of fire or thermal runaway, even when operated at elevated temperatures. In some instances. the alkali metal is lithium and the alkali metal anode is a lithium anode.
