Electric Car Revolution? Zinc Batteries Powered By Sun And Air
The Salamander of myth and legend: a creature which lives in water but renews its life in fire. It’s rubbish, Bunkum, steaming horse manure… a bit like an electric car with neither plug nor solar panels.
Except no one’s told those clever boffins over at Advanced Power and Energy Sources Transportation (APET) in Hong Kong. According to them, the Salamander and the cordless EV are about to step out of myth and into reality.
APET’s revolution centres upon how zinc air batteries can power EVs. The technology is proven on the small scale: hearing aid battery adverts dominate any Google search for “zinc air battery”.
Furthermore, as zinc air batteries need only zinc, air and water to produce electricity they are likely the most environmentally friendly ones around.
However, upscaling the technology from a hearing aid to a car has always been a problem.
Until now.
