Georgia Tech researchers led by Matthew McDowell, Affiliate Professor, in collaboration with Novelis, an aluminum producer, are using aluminum foil to make batteries with excessive power density and stability.

The workforce’s new battery system, detailed in Nature Communications, might allow EVs to run longer and be cheaper to fabricate than standard lithium-ion batteries. As an alternative of using pure aluminum, they blended small quantities of different components to make foils with sure microstructures. To know battery efficiency, they evaluated over 100 supplies. The aluminum anode saved extra lithium and power than standard anodes and produced high-energy-density batteries. The workforce can also be scaling up the batteries to review how measurement impacts aluminum habits.

“We would have liked to include a cloth that may deal with aluminum’s basic points as a battery anode,” mentioned Yuhgene Liu, a PhD scholar in McDowell’s lab and the primary writer of the paper. “Our new aluminum foil anode demonstrated improved efficiency and stability when applied in solid-state batteries, versus standard lithium-ion batteries.”
