Researchers have developed a new kind of battery, made entirely from abundant and inexpensive materials.

Then came deciding what to pair the aluminum with for the other electrode, and what kind of electrolyte to put in between to carry ions back and forth during charging and discharging. Surprisingly, the molten salt the team chose as an electrolyte simply because of its low melting point turned out to have a fortuitous advantage. One of the biggest problems in battery reliability is theThe three primary constituents of the battery are: left, aluminum; center, sulphur; and right, rock salt crystals.“We did experiments at very high charging rates, charging in less than a minute, and we never lost cells due to dendrite shorting,” Sadoway said.
In his view, this new battery formulation would be ideal for installations of about the size needed to power a single home or small to medium business, producing on the order of a few tens of kilowatt-hours of storage capacity.
