Although unsolved obstacles remain, these strategies have opened up interesting possibilities in the advancement of rechargeable Zn-air batteries, creating promising prospects for the energy and electronics industries.This Web page portal lists over 1,600 technical reports published as part of the JHRP, and subsequently JTRP, collaborative venture between Purdue University and the Indiana Department of Transportation. Specifically, an analysis of the latest publications will show that, through redesigning the anode, introducing alternative electrolytes, and engineering high-performing bifunctional oxygen catalysts, researchers have successfully prolonged the battery reversibility to a few thousand cycles and reached unprecedented energy efficiencies over 70%.


This article will review the current status of Zn-air batteries, discuss recent development trends including neutral and hybrid Zn-air batteries, and highlight future research needs. Nevertheless, despite a high energy density, low cost, and material abundance, the development of alkaline-based Zn-air batteries has been hampered by parasitic reactions at the Zn anode and sluggish oxygen redox kinetics. Currently a hot research topic, rechargeable zinc-air batteries are considered one of the most promising post lithium-ion battery technologies for utility-scale energy storage, electric vehicles, and other consumer electronics.
