Description
Zhuo Yang and colleagues write, in 2026, about a weakness of water-based zinc batteries that appears when they rest rather than cycle. Such batteries are cheap and safe candidates for storing solar and wind power. Yet capacity fades quickly during idle periods, a process called calendar ageing, and strategies against it have been scarce.
The commentary discusses research that used a molecular property, topological polar surface area, to screen additives. Water and acid accumulate at the zinc surface during storage and corrode it. Additives scoring high on that property reshaped the ionic layer at the interface. One additive, a phosphine oxide compound, gave zinc anodes much longer calendar life and higher efficiency, pointing to a practical fix for grid storage.
