      New Manufacturing Approach Slices Lithium-Ion Battery Cost in Half

      An advanced manufacturing approach for lithium-ion batteries, developed by researchers at MIT and at a spinoff company called 24M, promises to significantly slash the cost of the most widely used type of rechargeable batteries while also improving their performance and making them easier to recycle. In this so-called “flow battery,” the electrodes are suspensions of tiny particles carried by a liquid and pumped through various compartments of the battery.

      Future of Energy Storage

      MIT professor Fikile Brushett is in the process of taking the power generated by wind and solar, chemically lashing it to molecules derived from flora and fauna, and storing it in liquids until it’s needed to electrify our homes. The fact that such a system — if it's feasible — is likely years from reality doesn’t deter Brushett, the Raymond A. (1921) and Helen E. St. Laurent Career Development Professor of Chemical Engineering. An electrochemical engineer, Brushett works on applying fundamental electrochemistry to boost the performance and durability of our future energy storage systems.

      Re-inventing the Grid

      The challenge of selling any new idea is that it has to compete with every other new idea. The process is more difficult when the idea’s technology hasn’t existed and addresses an issue that some industries don’t see as a problem. Such is the reality of Ambri.  The Cambridge, Mass., company started in an MIT laboratory with Professor Donald Sadoway and David Bradwell MNG '06 PhD '11. The former had a concept to overhaul energy storage; the latter needed a thesis project. The eventual result was a spinoff dedicated to creating a simply designed, low-cost, liquid metal battery. Now, after almost 10 years of research, Sadoway and Bradwell have a prototype to test. It’ll be a first step in answering the essential question of whether the device can work. If it does, it won't be a minor shift: “The technology can really revolutionize the way the entire electric grid infrastructure is operated,” Bradwell says.

      Seeing How a Lithium-Ion Battery Works

      New observations by researchers at MIT have revealed the inner workings of a type of electrode widely used in lithium-ion batteries. The new findings explain the unexpectedly high power and long cycle life of such batteries, the researchers say. The findings appear in a paper in the journal Nano Letters co-authored by MIT postdoc Jun Jie Niu, research scientist Akihiro Kushima, professors Yet-Ming Chiang and Ju Li, and three others.
