Researchers have cracked a major challenge in battery technology by creating zinc-ion batteries that can cycle for over 360 days without degrading—a significant leap forward for large-scale renewable energy storage.

The breakthrough involves a clever interface engineering strategy that prevents zinc anodes from destabilizing. By creating a specially designed hydrated network layer on the battery's surface, scientists achieved ultra-stable performance: their test cells maintained 99.71% efficiency over thousands of cycles and retained 89% capacity after 12,000 cycles. This development addresses one of the biggest obstacles holding back zinc-ion batteries from powering the grid at scale. Read the full story →
