Study of disordered rock salts leads to battery breakthrough
A new family of integrated rock salt-polyanion cathodes opens door to low-cost, high-energy storage.
A lasting — and valuable — legacy
Professor Betar Gallant approaches electrochemistry with a strong inclination, inherited from her family, to work things out independently.
Light could boost performance of fuel cells, lithium batteries, and other devices
With many devices depending on the motion of ions, light could be used as a switch to turn ion motion on and off.
Designing better batteries for electric vehicles
As researchers consider materials for solid-state batteries, they also may want to consider how those materials could impact large-scale manufacturing.
Enriching solid-state batteries
MIT researchers demonstrate a method to make a smaller, safer, and faster lithium-rich ceramic electrolyte.
New manufacturing approach slices lithium-ion battery cost in half
Reinventing how these batteries are made also improves their performance and recyclability.
Disordered materials hold promise for better batteries
MIT researchers find that contrary to conventional wisdom, cathodes made of disordered lithium compounds can perform better than perfectly ordered ones.
Crash-testing lithium-ion batteries
Laboratory crash tests show both vulnerabilities and ways to improve the safety of lithium-ion batteries used in electric and hybrid vehicles.
Revealing how a battery material works
MIT team uncovers a reason why the hottest new material for rechargeable batteries works so well.
