What is the difference between aluminum & lithium sulfur batteries?

Aluminum–sulfur batteries have a theoretical energy density comparable to lithium–sulfur batteries, whereas aluminum is the most abundant metal in the Earth’s crust and the least expensive metallic anode material to date.

Are aluminum-sulfur batteries a good idea?

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.

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).

Do al-s batteries have a sulfur cathode?

So far, the publications on Al-S batteries mostly reported ex-situ studies of the Al-ion electrolyte and the sulfur cathode during cycling. After discharge, it has been determined the presence of all possible sulfur species, i.e. elemental sulfur, S 82−, S 62−, S 42−, S 22− and S 2−.

Are al s batteries better than aluminum-air batteries?

One unique advantage of Al S batteries, compared to aluminum-air (Al-air) batteries, is their closed thermodynamic system. Additionally, Al S batteries have a notable edge over AIBs because the cathode material in Al S batteries doesn't rely on intercalation redox processes.

Why are aluminum-based batteries becoming more popular?

The resurgence of interest in aluminum-based batteries can be attributed to three primary factors. Firstly, the material's inert nature and ease of handling in everyday environmental conditions promise to enhance the safety profile of these batteries.
