Forbes

Forbes reporter Amy Feldman spotlights the work of Prof. Yet-Ming Chiang, who has used his materials science research to “build an array of companies in areas like batteries, green cement and critical minerals that could really help mitigate the climate crisis.” Feldman notes that “as the climate crisis has become increasingly urgent, Yet-Ming Chiang’s ability to spin out companies from his research offers hope.” 

Somewhere on Earth

Prof. Michael Strano joins “Somewhere on Earth” podcast host Gareth Mitchell to discuss how he and his colleagues developed tiny batteries that could be used to power cell-sized robots. Roughly the thickness of a human hair, the new battery can create a current by capturing oxygen. “I would say we're making the LEGOs, the building blocks that go into robots,” Strano says. “We’re building the parts and it's an exciting time for the field.”

TechCrunch

Researchers at MIT have developed tiny batteries capable of powering cell-sized robots that can “execute tasks as varied as targeting drug delivery inside the human body to checking pipelines for gas leaks,” reports Brian Heater for TechCrunch. “Despite the barely visible size, the researchers say the batteries can generate up to 1 volt, which can be used to power a sensor, circuit or even a moving actuator.”

Wired

Prof. Martin Bazant speaks with Wired reporter Emily Mullin about the importance of proper battery disposal to reduce waste and ensure the materials can be reused. “What we don’t want is to be losing critical minerals from the supply chain,” explains Bazant. “We have to be able to recycle them.”

Forbes

Prakash Govindan PhD '12 and Anurag Bajpayee SM '08 PhD '12 co-founded AlkaLi, a startup working to extract lithium from brine and process it for use in batteries, reports Amy Feldman for Forbes. AlkaLi uses resins and membranes to more easily extract the lithium from brine, then relies on its own technology to concentrate the mineral, which ultimately is precipitated into a solid for use in batteries,” writes Feldman. 

Fast Company

MIT startup, 24M, has designed an EV battery with a range of 1,000 miles on a single charge, reports Adele Peters for Fast Company. “The extra-long range also can help the car’s battery last much longer,” explains Peters. “If you use a rapid charger to fully charge a battery, it can damage the battery, meaning it won’t last as long. Because it has such a long range, the new battery should rarely need a full rapid charge.”

The Boston Globe

Prof. Kripa Varanasi co-founded Alsym Energy, a startup “developing rechargeable batteries that won’t be based on lithium or cobalt,” reports Hiawatha Bray for The Boston Globe. “The founders said they expect to build batteries that match the performance of today’s lithium-ion cells but at about half the cost,” writes Bray.

Forbes

Prof. Emeritus Donald Sadoway co-founded Boston Metal, an MIT startup that has developed a carbon-free steel manufacturing process, reports Amy Feldman for Forbes. “Boston Metal’s process – which uses an electricity conducting, molten-metal proof anode to liquify iron ore, separating the pure metal without harmful byproducts – allows factories to create carbon-free steel as long as they use a clean energy source, such as hydroelectric power,” explains Feldman. “It also can create steel from lower-grade ores rather than relying on scarce high-grade ones. That’s an important advantage in terms of both cost and availability compared to other methods of making green steel, according to the company.”

Energy Wire

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. 

Associated Press

Prof. Jessika Trancik speaks with Associated Press reporter Alexa St. John to discuss electric vehicle emissions and ownership costs. Trancik notes, “buyers should consider total cost of ownership, which for an EV is generally less than that of a gas-powered counterpart due to savings on maintenance and fuel.”

Time Magazine

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.” 

National Defense Magazine

National Defense Magazine reporter Sean Carberry spotlights Mesodyne, an MIT startup that is developing a thermal photovoltaic power generator that could be used to help extend battery power during military missions. Mesodyne’s LightCell generator can deliver “high-efficiency direct current power from a quiet device with no moving parts that could change the equation of an operator carrying 100 pounds of batteries for a three-day mission,” Carberry explains. 

The Wall Street Journal

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.”

Associated Press

Studies by researchers at MIT have found “that shifting to electric vehicles delivers a 30% to 50% reduction in greenhouse gas emissions over combustion vehicles,” reports Tom Krisher for Associated Press. According to Prof. Jessika Trancik, “electric vehicles are cleaner over their lifetimes, even after taking into account the pollution caused by the mining of metals for batteries,” writes Krisher.

Associated Press

Prof. John Goodenough, who shared the 2019 Nobel Prize in chemistry for his work developing the lithium-ion battery, has died at age 100, reports Jim Vertuno for the AP. Goodenough “began his career at the Massachusetts Institute of Technology, where his research laid the groundwork for development of random-access memory for the digital computer.”
