Zinc-air battery created at Stanford may eventually replace lithium-ion

Researchers have developed a zinc-air battery that may eventually replace costly lithium-ion batteries.

Stanford scientists created the battery which is less costly, more energy-dense and safer than the traditional lithium-ion kind.

“There have been increasing demands for high-performance, inexpensive and safe batteries for portable electronics, electric vehicles and other energy storage applications,” said study author Hongjie Dai, a professor chemistry at Stanford.

“Metal-air batteries offer a possible low-cost solution.”

The zinc-air batteries blend atmospheric oxygen with zinc in a liquid alkaline electrolyte, while generating electricity.
