Insight into the bubble-induced overpotential towards high-rate charging of Zn-air batteries

This paper presents a detailed mathematical model based on the bubble evolution for three types of bubble-induced overpotentials in Zn-air batteries during high-rate charging, including activation overpotential, ohmic overpotential, and concentration overpotential, which provides theoretical guidance for the application of this technology towards the "peak carbon dioxide emissions and carbon neutrality" goal, and is expected to provide some thinking on the universal bubble problem in electrochemical systems.
