Latest Invention: Metal-Air Battery that Is 11 More Efficient than Lithium-Ion


Fluidic Energy, a spinoff firm from Arizona State University looks forward to come up with its new invention - a battery that would have an energy density 11 times greatest compared to the density of lithium-ion batteries; plus the new batteries will be about 60 percent cheaper than the lithium-ion ones.

US Department of Energy has given a $5.13 million research grant to Fluidic Energy so the latter could make its new invention come to life.

Together with a team of scientists Cody Friesen, a professor of materials science at Arizona State and founder of Fluidic Energy, is working on the creation of Metal-Air Ionic Liquid battery. The main aspect of the new battery is the ionic liquids that are used as the battery's electrolyte. These liquids will allow researchers overcome previous issues linked with earlier metal-air batteries.

It is worth mentioning that the advantage of ionic liquids, like the ones used in Fluidic Energy's new invention, is that they do not evaporate, which means that they are able to work for a much longer period time, reports TechnologyReview. Currently scientists look forward to achieve energy density from 900 to 1,600 watt-hours per kilogram. If successful, the new batteries will be able to help electric cars travel from 400 to 500 miles on a single charge.
