Abstract
Optimization of the charging reaction for zinc-air batteries remains a significant challenge. Here, we report a series of zinc-alcohol-air batteries that replace the oxygen evolution reaction with more thermodynamically favorable alcohol oxidation reactions for the charging reaction, using AuPd@C as the model catalyst. These batteries reduce the voltage window between charge and discharge by two orders of magnitude, achieving a remarkable round-trip efficiency (RTE) of over 99 % at 0.1 mA cm-2. This design demonstrates low charging voltage, high energy density (1020.6 kWh kg-1Zn) and excellent cyclic stability (over 1000 h), making it highly valuable for practical applications. The zinc-alcohol-air batteries utilizing C1-C4 alcohols show significant improvements in overall efficiency, offering great potential for biomass energy utilization and further development of zinc-air batteries.
