Solving Zinc Battery Woes with a Clever Coating

Zinc batteries are popular for their low cost and ability to store large amounts of energy. However, they face a significant issue: over time, the zinc components can degrade, produce harmful hydrogen gas, and develop unwanted structures called dendrites. These problems hinder the battery's performance. Unlike some other types of batteries, zinc batteries don’t naturally form a protective layer. Scientists have now developed a smart coating to tackle this problem.Initially, the coating is a thin layer of silver and indium. Over time, it transforms into a mixture of silver-zinc alloy and indium. This clever coating allows zinc ions to move smoothly and prevents the battery from corroding. Batteries with this coating work efficiently and maintain their storage capacity. This innovation could make zinc batteries more suitable for large-scale energy storage solutions.
