'Instantly Rechargeable' Battery Could Change the Future of Electric Cars (sciencedaily.com)

An anonymous reader quotes a report from Science Daily: A technology developed by Purdue researchers could provide an "instantly rechargeable" method that is safe, affordable and environmentally friendly for recharging electric and hybrid vehicle batteries through a quick and easy process similar to refueling a car at a gas station. John Cushman, Purdue University distinguished professor of earth, atmospheric and planetary science and a professor of mathematics, presented the research findings "Redox reactions in immiscible-fluids in porous media -- membraneless battery applications" at the recent International Society for Porous Media 9th International Conference in Rotterdam, Netherlands. Cushman co-founded Ifbattery LLC (IF-battery) to further develop and commercialize the technology. "Designing and building enough of these recharging stations requires massive infrastructure development, which means the energy distribution and storage system is being rebuilt at tremendous cost to accommodate the need for continual local battery recharge," said Eric Nauman, co-founder of Ifbattery and a Purdue professor of mechanical engineering, basic medical sciences and biomedical engineering. "Ifbattery is developing an energy storage system that would enable drivers to fill up their electric or hybrid vehicles with fluid electrolytes to re-energize spent battery fluids much like refueling their gas tanks." Mike Mueterthies, Purdue doctoral teaching and research assistant in physics and the third co-founder of Ifbattery, said the flow battery system makes the Ifbattery system unique. "Other flow batteries exist, but we are the first to remove membranes which reduces costs and extends battery life," Mueterthies said. Ifbattery's membrane-free battery demonstrates other benefits as well. "Membrane fouling can limit the number of recharge cycles and is a known contributor to many battery fires," Cushman said. "Ifbattery's components are safe enough to be stored in a family home, are stable enough to meet major production and distribution requirements and are cost effective." For the visual learners, Purdue Research Park has uploaded a video about Ifbattery's "instantly rechargeable" method.

    It is a flow battery and the idea has been around for a long time.

    The biggest problem is the nasty nature and quantity of chemicals used

      Well, I didn't see anything about energy density, which is the main problem with flow batteries. They're lower than Lithium-ion.

      Furthermore, membrane-less flow batteries already exist. The problem is that they rely on laminar flow, which is basically impossible to maintain under any sort of acceleration. So, no. Can't use them in cars.

      I call this a meaningless hype article

    Don't be stupid and lazy. We will definitely have electric cars that are cheaper to manufacture, cheaper to operate, and cheaper to maintain than ICE's in the very near future (this coming decade, guaranteed).

    Any kind of mandates are just going to slow down the industry which is already on trajectory to exceed our ambitious desires.

    YOU are not smarter than the people who are building these things, so stop pretending like you have more information than they do.

    No, it is a real battery. A variant on a flow cell (look it up) that has the novel ability to work without membranes.

    From TFS: "but we are the first to remove membranes which reduces costs and extends battery life"

    The battery life of flow batteries is already ahead of all others which is why they are being seen as a potentially better alternative in grid applications.

    From TFS: "Membrane fouling can limit the number of recharge cycles and is a known contributor to many battery fires"

    As above the recharge cycles of flow batteries are already well above every other type of battery. And fire? Well the fact that flow batteries don't catch fire is one of their key selling points.

    Is this just marketing fluff that is using buzzwords to try and get across? The big problem with flow batteries is their energy density at best is currently less than half of an equivalent lithium battery system. This is a far more important problem to fix.

    Mind you I do like what they are talking about. One of the big problems with electric cars is the grid connections for fast chargers. It makes the highway rest stop model of petrol stations difficult to convert to electric. All you need is 3 fast chargers in use at once and you're using more power than the currently biggest petrol station in Europe, and many of the highway stops are in the middle of nowhere which don't lend themselves to easy electrical infrastructure upgrades.
