Batteries

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.

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.

The Boston Globe honored a number of MIT faculty and alumni in their Tech Power Players 50, a list of the “most influential – and interesting – people in the Massachusetts technology scene.” MIT honorees include Professor Yet-Ming Chiang, Senior Lecturer Brian Halligan, Professor Tom Leighton, Professor Silvio Micali, Katie Rae (CEO and managing partner for The Engine), and Professor Daniela Rus (director of CSAIL and deputy dean of research for the MIT Schwarzman College of Computing). 

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.

Daily Beast reporter Tony Ho Tran writes that MIT researchers have developed a tiny fuel cell that can transform glucose into electricity. “The team behind the new fuel believes it could potentially be used as a coating on medical implants like artificial hearts or pacemakers,” writes Tran. “Those implants could be powered passively while in use without the need for expensive and cumbersome batteries that take up valuable real estate in the body.”

A new report by researchers from MIT’s Energy Initiative (MITEI) underscores the feasibility of using energy storage systems to almost completely eliminate the need for fossil fuels to operate regional power grids, reports David Abel for The Boston Globe. “Our study finds that energy storage can help [renewable energy]-dominated electricity systems balance electricity supply and demand while maintaining reliability in a cost-effective manner,” says Prof. Robert Armstrong, director of MITEI.

MIT researchers have developed a new fuel cell that takes glucose absorbed from food in the human body and turns it into electricity, reports Gwen Egan for Boston.com. “That electricity could power small implants while also being able to withstand up to 600 degrees Celsius — or 1112 degrees Fahrenheit — and measuring just 400 nanometers thick,” writes Egan.

Researchers at MIT have built a highly efficient thermophotovoltaic cell that converts incoming photons to electricity, reports Kevin Hurler for Gizmodo. “We developed this technology—thermal batteries—because storing energy as heat rather than storing it electrochemically is 10 to 100 times cheaper," explains Prof. Asegun Henry. 

Prof. Yet-Ming Chiang ’85, Prof. Craig Carter and Throop Wilder co-founded MIT spinout 24M, which “will manufacture next-generation lithium-ion batteries using its cell technology,” reports Reuters.
