Rechargable Zinc-Air Battery

Aug-15-17 A rechargeable zinc-air battery made from common materials could offer a safe and affordable alternative to lithium-ion.

Although zinc-air batteries show a high energy density, they can only be recharged by replacing the zinc altogether or by using electrocatalysts derived from rare-earth minerals. To help overcome this obstacle, a team from the University of Sydney created electrocatalysts made of common elements with their composition, size and crystallinity carefully controlled to produce an efficient recharging catalyst.

According to the team, the new battery can be charged and discharged multiple times while losing less than 10 percent efficacy.
