New Coating Stops Zinc Batteries From Losing Power to Hidden Corrosion (opens in new tab)

Researchers identified galvanic corrosion between deposited zinc and current collectors as a major, previously underappreciated cause of irreversible zinc loss in anode-less aqueous zinc batteries. A PVDF/CeF3 hybrid interface suppressed corrosion, guided dense zinc deposition, and enabled longer cycling, lower self-discharge, and pouch-cell energy densities exceeding 90 Wh L?¹.
