How does oxygen reaction kinetics affect the performance of zinc–air batteries?
Nevertheless, sluggish oxygen reaction kinetics at the air electrode seriously compromises their power density and cycling stability. As one of the main components, the catalyst significantly impacts the performance of zinc–air batteries.
What is a positive electrode in a zinc based battery?
Positive electrode: In zinc-based flow batteries (ZFBs), the positive electrode typically involves redox-active species dissolved in the circulating electrolyte, rather than a solid electrode material common in static batteries, such as aqueous zinc-ion batteries .
What is the working principle of a zinc-based flow battery?
The working principle of the zinc-based flow battery is mainly based on the REDOX reaction of zinc, in which the negative electrode is the metal zinc plate, the auxiliary electrolyte, and the positive electrode is the flowing active electrolyte .
How does a catalyst affect the performance of zinc–air batteries?
As one of the main components, the catalyst significantly impacts the performance of zinc–air batteries. Finding high-performance bifunctional catalysts for both the oxygen reduction reaction and oxygen evolution reaction is of great importance for the practical application of zinc–air batteries.
