Created from low-cost and plentiful aluminum, elemental sulfur, and common salt, their new battery is cheap and fire-resistant, can store enough energy to electrify a house or a car, and can charge to full capacity in less than a minute.
Are aluminum & sulfur batteries a good energy storage material?
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.
What is an aluminum-sulfur battery?
The aluminum-sulfur battery offers cost-effective, fire-resistant energy storage, challenging lithium-ion dominance in safety and affordability. The three primary constituents of the battery are aluminum (left), sulfur (center), and rock salt crystals (right).

An aluminum-sulfur battery that is lightweight, doesn't burn, and can be made much more cheaply than the lithium-ion batteries currently in use. When MIT's Donald Sadoway sits down with colleagues to invent something, as he often does, the bar is set high. It's not enough, he believes, for a new technology to be novel and interesting.
Is a rechargeable aluminum–sulfur (al–s) battery reversible?
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 AlCl 3 /acetamide.
MIT engineers designed a battery made from inexpensive, abundant materials, that could provide low-cost backup storage for renewable energy sources. Less expensive than lithium-ion battery technology, the new architecture uses aluminum and sulfur as its two electrode materials with a molten salt electrolyte in between.
