Rechargeable zinc-air battery with bifunctional electrocatalyst of copper oxide and graphene nanoplatelets
Rechargeable zinc-air batteries have been identified as promising technologies for energy storage. However, developing cost-effective electrocatalysts that can efficiently facilitate the oxygen evolution reaction (OER) and oxygen reduction reaction (ORR) is crucial for their advancement. This work investigates synthesized electrocatalysts composed of graphene-Cu2O deposited on carbon cloth by doctor blading casting method as bifunctional electrodes in a rechargeable Zn-air battery. The battery integrated with graphene-Cu2O as the air-cathode electrocatalyst showed superior performance in terms of cycling stability compared to that without Cu2O. This enhanced performance is attributed to the reversibility of Cu+/Cu2+ species during the redox reactions facilitated by the high electrical conductivity of graphene. Therefore, the results suggest the potential of the synthesized electrodes for advancing the development of rechargeable Zn-air batteries.
期刊介绍：
Electrochemistry Communications is an open access journal providing fast dissemination of short communications, full communications and mini reviews covering the whole field of electrochemistry which merit urgent publication. Short communications are limited to a maximum of 20,000 characters (including spaces) while full communications and mini reviews are limited to 25,000 characters (including spaces). Supplementary information is permitted for full communications and mini reviews but not for short communications. We aim to be the fastest journal in electrochemistry for these types of papers.
