SLAC, MIT, TRI researchers advance machine learning to accelerate battery development; insights on fast-charging

Green Car Congress

Instead of using machine learning just to speed up scientific analysis by looking for patterns in data—as typically done—the researchers combined it with knowledge gained from experiments and equations guided by physics to discover and explain a process that shortens the lifetimes of fast-charging lithium-ion batteries.

Novel Li-metal electrode design could lead to more powerful solid-state batteries

Green Car Congress

Researchers at MIT and their colleagues are proposing a new design for electrodes that, based on the long-sought goal of using pure lithium metal as the anode, could lead to longer-lived batteries with higher energy densities. —Ju Li. The metal then shrinks again during discharge, as the battery is used.

24M emerges from stealth mode with new semi-solid Li-ion cell; <$100/kWh by 2020

Green Car Congress

Stealth-mode battery start-up 24M has introduced its new semi-solid lithium-ion cell. Together, our inventions achieve what lithium-ion has yet to do—meet the ultra-low cost targets of the grid and transportation industries. The lithium-ion battery is a brilliant, enabling technology, but its economics are flawed.

New Carbon Nanotube Electrode Material for Li-ion Batteries Tackles the Power Performance Gap Between Electrochemical Capacitors and Batteries

Green Car Congress

Researchers at MIT have developed a new carbon nanotube electrode material for a Li-ion battery based on redox reactions of functional groups on the surfaces of the nanotubes. Funding for the work was provided by the Dupont-MIT Alliance; the US Office of Naval Research; and the MRSEC Program of the National Science Foundation.
