Aluminum metal anode rechargeable batteries with sulfur-carbon composite cathodes and inorganic chloroaluminate ionic liquid.

Promising sulfurized polyethylene glycol (SPEG) composite cathodes with a high-rate capability over 3000 mA g -1 at 393 K are fabricated for Al metal anode rechargeable batteries with a 61.0-26.0-13.0 mol% AlCl 3 -NaCl-KCl inorganic ionic liquid electrolyte. The combination of the SPEG composite cathodes and chloroaluminate inorganic IL can readily enhance the performance of the Al-S batteries, e.g. , discharge capacity and cycle stability.
