New Rechargeable Zinc-Air Batteries Coming Soon
Published in October 29th, 2009
(PhysOrg.com) – A new breed of rechargeable zinc-air batteries is soon to be available, and may replace lithium-ion batteries in cell phones, laptops and other consumer items. Lithium-ion batteries store only a third of the energy and cost around twice as much as the new batteries.
The Swiss company ReVolt, from Staefa, plans to release the new batteries next year, initially as small batteries for use in hearing aids, and later for cell phones. Eventually much larger batteries are planned for electric vehicles.

Zinc-air batteries need oxygen from the air to generate the current. They are safer than lithium-ion batteries because they do not contain volatile materials, and therefore do not catch fire. Non-rechargeable zinc-air batteries have been available for some time, but rechargeable versions have proved more difficult to develop.
