Researchers at MIT have developed a cathode, the negatively-charged part of an EV lithium-ion battery, using “small organic molecules instead of cobalt,” reports Hannah Northey for Energy Wire. The organic material, "would be used in an EV and cycled thousands of times throughout the car’s lifespan, thereby reducing the carbon footprint and avoiding the need to mine for cobalt,” writes Northey.
Prof. Yet-Ming Chiang has been named to the TIME 100 Climate list, which highlights the world’s most influential climate leaders in business. “When it comes to cleantech, if it won’t scale, it doesn’t matter,” Chiang says. “This is a team sport—companies large and small, and governments state and federal, need to work together to get these new technologies out there where they can have impact.”
Wall Street Journal reporter Scott Patterson spotlights Form Energy, an MIT startup that will produce long-duration batteries using an electrochemical reaction that turns iron into rust and back again. Patterson notes that the goal at Form Energy was to “develop batteries that were cheap, didn’t catch fire, didn’t need scarce and costly metals like cobalt and lithium, and could produce electricity for a long time.”
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. 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.
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."
TechCrunch reporter Devin Coldewey writes that a new report by MIT researchers finds that in order to successfully transition to a renewable energy grid, the federal government must intervene to help build green energy storage at a scale that will meet the nation’s needs. “The federal government has the means both to subsidize the utilization of existing storage options and to fund intensive research into new and promising ones,” writes Coldewey of the report’s findings.
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.
Prof. Donald Sadoway is the recipient of the 2022 European Inventor Award for his work in liquid metal batteries, reports WBUR. “MIT says the battery could enable the long-term storage of renewable energy,” says WBUR.
WBUR reporter Bruce Gellerman spotlights a new report by MIT Energy Initiative (MITEI) researchers that emphasizes the importance of developing and deploying new ways to store renewable energy in order to transition to clean energy. “There are a variety of technologies and if we can develop [them] and drive those costs down, it could make getting to net-zero or zero in the electricity sector more affordable,” says Prof. Robert Armstrong, MITEI director.
