Australian Scientists Just Worked Out How Zinc-Air Batteries Can Replace Lithium-Ion Batteries

Researchers at the University of Sydney just worked out how to solve one of the biggest problems standing in the way for zinc-air batteries to replace lithium-ion batteries as our go-to for modern electronics.

Zinc-air batteries are batteries powered by zinc metal and oxygen from the air. Because of how much zinc metal we have around the world (it's a lot), these batteries are much cheaper to produce than lithium-ion batteries, and they can also store more energy (theoretically five times more than that of lithium-ion batteries), are much safer and are more environmentally friendly.

Researcher Dr Li Wei, also from the University's Faculty of Engineering and Information Technologies, said trials of zinc-air batteries developed with the new catalysts had demonstrated "excellent rechargeability" – including less than a 10 percent battery efficacy drop over 60 discharging/charging cycles of 120 hours.
