MIT team develops approach to control dendrite propagation in solid-state batteries

Green Car Congress

MIT researchers led by MIT Professor and colleagues at Brown University have developed an approach to controlling dendrite propagation in solid-state batteries. The process of dendrite formation normally takes place deep within the opaque materials of the battery cell and cannot be observed directly. —Cole Fincher.

MIT, Brookhaven team develops simple method for stabilizing interfaces in solid-state lithium-ion batteries

Green Car Congress

Solid-state batteries could potentially not only deliver twice as much energy for their size, they also could virtually eliminate the fire hazard associated with today’s lithium-ion batteries. The new findings could potentially be applied rapidly to battery production, Yildiz says.

MIT electrolyte enables ultra-high voltage Ni-rich cathodes in Li-metal batteries

Green Car Congress

MIT researchers and colleagues at two national laboratories have developed a sulfonamide-based electrolyte that enables stable cycling of a commercial LiNi 0.8 V in lithium-metal batteries (LMBs). V lithium-metal battery can retain >88% capacity for 90 cycles. O 2 cathode with a cut-off voltage up to 4.7?V —Yang Shao-Horn.

MIT researchers develop optimized sulfidation separation process for rare earth and other key metals

Green Car Congress

New processing methods developed by MIT researchers could help ease looming shortages of the essential metals that power everything from phones to automotive batteries by making it easier to separate these rare metals from mining ores and recycled materials. A paper on their work is published in the journal Nature. —Caspar Stinn.

MIT, Scripps study examines behavior of midwater sediment plumes from deep-sea nodule mining

Green Car Congress

A region of the central Pacific—the Clarion Clipperton Fracture Zone (CCFZ)—is estimated to contain vast reserves of polymetallic nodules that are rich in nickel and cobalt—minerals that are commonly mined on land for the production of lithium-ion batteries in electric vehicles, laptops, and mobile phones. earlier post ).

MIT: hybrid cathodes could boost energy capacity of lithium-sulfur batteries

Green Car Congress

Researchers at MIT and in China are proposing a new class of dense intercalation-conversion hybrid cathodes by combining intercalation-type Mo 6 S 8 with conversion-type sulfur (HMSC) to realize a Li–S full cell. electrolyte) and eventually redeposit somewhere else as solid phases. … The net effect of using the new material is substantial.
