An interesting advance in battery applications

Watts Up With That?

From Stanford University encouraging news, a rechargeable Zinc-air battery would put electric cars into the realm of reasonable practicality, where with lead-acid batteries they are currently not.

Stanford scientists develop high-efficiency zinc-air battery

Stanford University scientists have developed an advanced zinc-air battery with higher catalytic activity and durability than similar batteries made with costly platinum and iridium catalysts. The results, published in the May 7 online edition of the journal Nature Communications, could lead to the development of a low-cost alternative to conventional lithium-ion batteries widely used today.

“There have been increasing demands for high-performance, inexpensive and safe batteries for portable electronics, electric vehicles and other energy storage applications,” said Hongjie Dai, a professor chemistry at Stanford and lead author of the study. “Metal-air batteries offer a possible low-cost solution.”
