Results of measuring the conductivity of electrolytes with ionic liquids (IL) based on quaternary ammonium salts, promising for innovative lithium-sulfur batteries are presented. The conductivity of IL in a propylene carbonate-dimethylformamide mixture is 5.2·10-4. Sm/cm depending on the solvent ratio. The presence of lithium salt leads to higher values up to 8.9·10-3 Sm/cm.

Lithium–sulfur batteries (LSBs) have attracted wide attention, but the shuttle effect of polysulfide hinders their further practical application. Herein, we develop a new strategy to construct a Ketjen black@zeolite imidazole framework-8/polypropylene composite separator. Such a separator consists of Ketjen black (KB), zeolite imidazole framework-8 (ZIF-8) and polypropylene (PP) with a low coating load of 0.06 mg cm−2 and is denoted as KB@ZIF-8/PP. KB@ZIF-8/PP can absorb polysulfides because of the Lewis acid-base interaction between ZIF-8 and polysulfides. This interaction can reduce the dissolution of polysulfides and suppress the shuttle effect, thereby enhancing the electrochemical performance of the battery. When tested at a current density of 0.1 C, an LSB with a KB@ZIF-8/PP separator exhibits low polarization and achieves a high initial capacity of 1235.6 mAh/g and a high capacity retention rate of 59.27% after 100 cycles.

All-solid-state electrochemical energy storage devices are highly in demand for future energy storage, where quasi-solid-state systems, such as gel polymer electrolytes, represent an important step towards this goal.
