Swiss Zinc-Air Batteries Store Three Times the Energy of Lithium Ions
Yale Environment 360 —
A Swiss company has introduced a rechargeable zinc-air battery that has three times the storage of lithium ion batteries and costs only half as much. ReVolt plans to commercialize a small version of the battery for use in hearing aids by next year, and then continue introducing larger versions, including batteries for cellphones and electric bicycles — and, perhaps eventually, electric cars. The technology is based on a battery designed by the Norwegian research institute SINTEF. While the typical battery contains the reactants needed to generate ...
SINTEF high-energy zinc-air batteries to outdo Lithium-ion

... after relatively few charges. This is made possible by the unique mechanism these batteries employ. The battery comes with a cover that lets in air, oxygen rather. Next, there is a porous air electrode with a water-based electrolyte to discourage hydroxyl ions from forming. Finally, a zinc electrode oxidizes zinc and releases electrons to generate a current. When it recharges, the zinc oxide flows back via the air electrode and zinc is formed with the release of oxygen.

A Powerful Rechargeable Zinc-Air Battery To Be Released Soon
GoodCleanTech —
... will soon be releasing a button cell battery for hearing aids in the market next year. But unlike other products available in the market, ReVolt's battery uses the zinc-air battery technology developed by Norwegian research institute SINTEF. ReVolt has raised 24 million Euros in funding for the development of the technology, with the release of zinc-air based batteries for cell phones and electric bikes expected within a few years. ReVolt claims its technology overcomes the biggest hurdle in developing rechargeable zinc-air batteries - the inability to last as ...
