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

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. While the safety benefits of this solid electrolyte replacement are widely acknowledged, the broader safety of Li-metal anode solid-state batteries with high energy density has not been critically examined.
