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.
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.
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. 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.
24M Technologies, an MIT startup, and Volkswagen Group are joining forces to "manufacture next-generation lithium-ion EV batteries using the 24M SemiSolid platform,” reports Mark Kane for Inside EVs.
A new study by Prof. Jessika Trancik and postdoctoral associate Micah Ziegler examining the plunge in lithium-ion battery costs finds that “every time output doubles, as it did five times between 2006 and 2016, battery prices fall by about a quarter,” reports The Economist. “A doubling in technological know-how, measured by patent filings, is associated with a 40% drop in price.”
MIT startup SolidEnergy Systems has signed a deal with GM to develop next-generation electric vehicle batteries that are expected to cut the cost of the technology by 60%, reports Michael Wayland for CNBC. “The new batteries feature lithium metal instead of lithium-ion like today’s EVs use,” writes Wayland. “The switch changes the chemistry of the battery to enable higher energy density and longer range from a similar-sized battery or comparable range with a smaller battery.”
Popular Mechanics reporter John Wenz writes that a new study co-authored by MIT researchers examines how lithium moves through batteries. The findings could be used to help build a smarter battery, including “designing selective transport channels, additional shielding on batteries, or a battery additive that would prevent against corrosion or the formation of hot spots.”
Prof. Donald Sadoway speaks with Forbes contributor Arne Alsin about the future of sustainable energy and battery design. “We definitely have to be bolder in our innovation when it comes to what goes beyond lithium-ion,” says Sadoway. “We have to apply the criterion ‘If successful, how big is the impact?’ And we have to have the courage to fail.”
