@ 2022/08/26Who needs Lithium?
Boffins at MIT describe new aluminum-sulfur batteries that are made entirely from abundant and inexpensive materials and can be charged in less than a minute.
The batteries use aluminum and sulfur as its two electrode materials, sandwiching a molten salt electrolyte and have been described in the popular science magazine Nature.
MIT Professor Donald Sadoway said the battery cells could endure hundreds of cycles at exceptionally high charging rates, with a projected cost per cell of about one-sixth that of comparable lithium-ion cells. They showed that the charging rate was highly dependent on the working temperature, with 110 degrees Celsius (230 degrees Fahrenheit) showing 25 times faster rates than 25 C (77 F).
