AI Insight
Researchers developed a copper-nickel cyanide coordination polymer that enables symmetric multisite redox reactions for aqueous proton batteries. The material demonstrates high-rate performance and exceptional cycling stability by utilizing both metal centers (Cu and Ni) as well as the cyanide ligands for reversible proton storage. This symmetry-enabled approach allows for increased charge storage capacity while maintaining structural integrity during repeated charge-discharge cycles.
Why it matters
This advance addresses key limitations in aqueous battery technology by providing a path toward safer, more sustainable energy storage alternatives to lithium-ion batteries. The high cycling stability and fast charging capabilities could enable practical applications in grid-scale energy storage and electric vehicles where safety and longevity are critical.
