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. 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. A paper on their work appears in Joule.

Researchers use carbon-based anodes with “bumpy” surfaces for Li-ion batteries that last longer in extreme cold

Green Car Congress

the key to addressing the low-temperature capacity loss lies in adjusting the surface electron configurations of the carbon anode to reinforce the coordinate interaction between the solvated Li + and adsorption sites for Li + desolvation and reduce the activation energy of the charge-transfer process. . … —Lu et al.
