A novel zinc-air flow battery is first designed for long-duration energy storage. A max power density of 178 mW cm −2 is achieved by decoupling the electrolyte. Fast charging is realized by introducing KI in the electrolyte as a reaction modifier. Zinc dendrite and cathode degradation can be alleviated at lower charging voltage.
Electrically rechargeable zinc–air flow batteries (ZAFBs) remain promising candidates for large-scale, sustainable energy storage. The implementation of a flowing electrolyte system could mitigate ...

Exploring effective energy storage systems is critical to alleviate energy scarcity. Rechargeable zinc-air batteries are promising energy storage devices. However, conventional rechargeable zinc-air battery systems face many challenges associated with electrolytes and electrodes, causing inferior electrochemistry performance.
In rechargeable zinc–air flow batteries, it achieves a peak power density of 169.5 mW cm –2 and a voltage gap that is only 1.6% larger than the original after 700 h. This work surmounts critical challenges in the ORR kinetics for zinc–air batteries. To access this article, please review the available access options below.
This strategy effectively combines both light and electrical energy conversion/storage mechanisms. In addition, light-assisted rechargeable zinc-air batteries can achieve photocharging with or without applied electrical bias by partially using solar energy and the acceleration of oxygen reduction/evolution reaction kinetics.
