Georgia Tech researchers develop aluminum-foil-based anodes for all-solid-state Li-ion batteries

Green Car Congress

Woodruff School of Mechanical Engineering and the School of Materials Science and Engineering, is using an aluminum-foil-based anode in a solid-state Li-ion battery to create batteries with higher energy density and greater stability. The new battery system is detailed in an open-access paper in Nature Communications.

Researchers propose approach for recycling all-solid-state Li-ion batteries

Green Car Congress

With the current global projection of over 130 million electric vehicles (EVs), there soon will be a need for battery waste management. Especially for all solid-state lithium-ion batteries (lithium ASSBs), aspects of waste management and circular economy have not been addressed so far. La 3 Zr 1.5 La 3 Zr 1.5 202202361

DOE researchers suggest solid-state batteries may not be a safety slam-dunk; thermodynamic models evaluate solid-state and Li-ion safety

Green Car Congress

Recent battery fires have renewed investigation of the safety of Li-ion batteries. One possible path to battery safety is a solid-state battery that replaces the volatile and flammable liquid electrolyte with a non-flammable solid electrolyte. A paper on their work appears in Joule. Bates et al.
