The wonders of ionic liquids, and how they can dramatically raise the bar on energy storage

I have to be honest, up until last week I’d heard a lot about the potential of metal-air batteries — i.e. zinc-air, lithium-air, etc… — but really didn’t know much about the batteries, how they were made, why they are be potentially better, and what challenges need to be overcome for them to unseat the current king of batteries, lithium-ion technology. Then I was put onto an Arizona-based company called Fluidic Energy, which recently received $5.13 million in funding from the U.S. Department of Energy as part of the recently announced first-phase of ARPA-E awards. Fluidic, a spin-off of Arizona State University, will use this money over the next few years to achieve its mission: a metal-air battery that’s up to 11 times more energy dense than the best lithium-ion battery today, and potentially half or even a third of the cost.

Certainly a big mission, but after chatting with Cody Friesen, Arizona State professor and founder of Fluidic, I quickly realized it’s not mission impossible. And it gave me great hope that five or 10 years from now, whether it’s Fluidic or EEStor or Premium Power or some other company, the big breakthrough we’re looking for will happen. And that, my friends, is an exciting thing.

I urge you to read this story on MIT Technology Review, posted today, which explains what Fluidic is doing and why it may overcome many of the challenges that have dogged the commercial, mass-market introduction of rechargeable metal-air batteries.
