Writing for Scientific American, John Fialka spotlights Form Energy, an MIT spinout designing an iron-air battery that “could help decarbonize the nation’s power sector more cheaply than lithium-ion storage systems.” Fialka explains that “unlike current lithium-ion batteries that require expensive materials mostly from other countries such as lithium, cobalt, nickel and graphite, the proposed battery stores electricity using widely available iron metal.”
Physics World has named two research advances by MIT researchers to its list of the Top 10 Breakthroughs of the Year. Prof. Gang Chen and his colleagues were selected for their work “showing that cubic boron arsenide is one of the best semiconductors known to science.” Prof. Asegun Henry, grad student Alina LaPotin and their colleagues were nominated for “constructing a thermophotovoltaic (TPV) cell with an efficiency of more than 40%.”
Popular Science reporter Helen Bradshaw writes that MIT researchers have improved the energy capacity of nonrechargeable batteries, the batteries used in pacemakers and other implantable medical devices, by employing a new type of electrolyte. “Expanding the life of primary batteries may also make them sustainable contenders,” writes Bradshaw. “Fewer batteries will have to be used in pacemakers as their lifespans increase, decreasing overall battery waste in addition to reducing the number of battery replacement surgeries needed.”
Dharik Mallapragada, a principal research scientist at the MIT Energy Initiative, speaks with Vox reporter Neel Dhanesha about the pressing need to find new ways to store renewable energy. “We need to think about solutions that go beyond conventional lithium-ion batteries,” says Mallapragada. “No single technology is going to make this happen. We have to think about it as a jigsaw puzzle, where every piece plays its role in the system.”
Prof. Kripa Varanasi and his colleagues have founded Alsym Energy, a startup working toward developing a lithium battery alternative, reports Hiawatha Bray for The Boston Globe. The founders say “they’ve built a new kind of rechargeable battery that delivers the performance of lithium ion cells at half the cost,” writes Bray.
Prof. Jessika Trancik speaks with Science Friday host Ira Flatow about the future of electric vehicles. “I think there is a lot happening in this space both coming from the private sector and then also from these government incentives coming in to accelerate that process,” says Trancik.
MIT spinoff Gradiant, a water treatment facility developer, is working on new technology aimed at limiting the amount of water needed to produce lithium, reports Annie Lee and Janet Wu for Bloomberg. Gradiant’s process “can vastly improve lithium recovery and allow almost all wastewater to be recycled, has been developed in connection with Schlumberger’s NeoLith Energy venture,” writes Lee and Wu.
Prof. Emeritus Donald Sadoway and his colleagues have developed a safer and more cost-effective battery to store renewable energy, reports David Abel for The Boston Globe. The battery is “ethically sourced, cheap, effective and can’t catch fire,” says Sadoway.
In a letter to the editor, Professor Emeritus Donald R. Sadoway writes to The New York Times about the importance of developing new batteries that utilize readily available materials. “We need to attack it the old-fashioned American way: Invent our way out,” writes Sadoway. “This means devise a new battery chemistry that requires no cobalt, no nickel, no manganese and no lithium, but instead is made of substances that are earth-abundant and readily available here in North America.”
Researchers from MIT and elsewhere have developed a new cost-effective battery design that relies on aluminum ion, reports Robert F. Service for Science. “The battery could be a blockbuster,” writes Service, “because aluminum is cheap; compared with lithium batteries, the cost of materials for these batteries would be 85% lower.”
Researchers at MIT have developed a battery that uses aluminum and sulfur, two inexpensive and abundant materials, reports Alex Knapp and Alan Ohnsman for Forbes. “The batteries could be used for a variety of applications,” write Knapp and Ohnsman.
MIT researchers have created a new battery using inexpensive and plentiful materials to store and provide power, reports Tony Ho Tran for The Daily Beast. “The study’s authors believe that the battery can be used to support existing green energy systems such as solar or wind power for times when the sun isn’t shining or the air is still,” writes Tran.
Prof. Donald Sadoway and his colleagues have developed a battery that can charge to full capacity in less than one minute, store energy at similar densities to lithium-ion batteries and isn’t prone to catching on fire, reports Alex Wilkins for New Scientist. “Although the battery operates at the comparatively high temperature of 110°C (230°F),” writes Wilkins, “it is resistant to fire because it uses an inorganic salt that can’t burn as its electrolyte, the material that allows charge to flow inside a battery.” Sadoway explains that “this is a totally new battery chemistry."
Prof. Yoel Fink speaks with Washington Post reporter Pranshu Verma about the growing field of smart textiles and his work creating fabrics embedded with computational power. Fink and his colleagues “have created fibers with hundreds of silicon microchips to transmit digital signals — essential if clothes are to automatically track things like heart rate or foot swelling. These fibers are small enough to pass through a needle that can be sown into fabric and washed at least 10 times.”
Ambri, an MIT startup that has developed a liquid-metal battery that can be used for grid-level storage of renewable energy, has announced that it is months away from delivering its first battery to a customer, reports Jacob Wycoff for CBS Boston. "We want to have a battery that can draw from the sun even when the sun doesn't shine," said Prof. Donald Sadoway of the inspiration for Ambri’s battery.
