Abstract

Both aluminum and sulfur are promising materials for future-generation electrochemical energy storage technology owing to their natural abundance, low cost, and high capacity. However, a rechargeable aluminum-sulfur (Al-S) battery with high energy density suffers from poor reversibility and very short cycle life. This paper demonstrates an Al-S battery which comprised of a MWCN/S cathode, aluminum anode and deep eutectic solvent of AlCl3/acetamide. The Al-S battery delivers an initial capacity of ~453 mAh g-1and maintains a capacity of up to ~358 mAh g-1after 200 cycles.
