Researchers from Hunan University, University College London, and the University of Oxford have discovered a novel metal-nitrogen-carbon catalyst for zinc-air batteries (ZABs). It performs better than noble metal catalysts, increasing the usefulness and efficiency of ZAB technology. The scientific publication Nano Research Energy published the breakthrough. Zinc is oxidized by airborne oxygen in zinc-air batteries. Iron, cobalt, and nickel are the three non-noble metal atoms combined in the newly created catalyst to enhance both charging and discharging operations and increase the cost-effectiveness of ZABs. This catalyst is part of a solid-state ZAB electrolyte consisting of a flexible carbon dot/polyvinyl alcohol … Continue reading Oxford and Hunan University’s Latest Innovation: A Triple-Metal Catalyst Boosts Zinc-Air Battery Performance, Offering High Energy Densities of 1084 Wh kg−1
