Affordable EV batteries made from everyday items, new discovery by scientists

According to media reports, researchers at the Massachusetts Institute of Technology (MIT) have developed a new battery built using cost-effective common materials. These batteries are said to pack in high density at a fraction of the cost of lithium-ion battery packs.

As per reports, these cost-effective batteries use materials like Aluminium, Sulfur and molten salt. John F Elliot, Emeritus of Materials Chemistry at MIT, stated that Aluminium is the most abundant metal found on Earth and could be easily substituted for lithium. The metal paired with sulfur is suited to "carry ions back and forth during charging & discharging", while molten salt's relatively low melting point makes it an effective electrolyte. The overall process would also be cheaper than the one currently in place, which uses precious earth metals like lithium, cobalt and nickel.

Reports, however, state that while it is premature to suggest that these batteries will bring about immediate change. It does seem to be a step towards making safer and cost-effective batteries in the future.

Why are they calling it new? Is it not similar to Aluminum Ion battery with molten salt electrolyte??

For example, the major challenge of "molten" to sub "molten" operation is being addressed:

Check the names, though!

Denial? Discrediting?

Or maybe I misread!
