Flame Suppression in Lithium-Ion Batteries During Thermal Runaway Through Solvent Design Considering the Volatility-Flammability Relationship. [PDF]

open access: yesAdv Sci (Weinh)
An asymmetric sulfonate solvent forms thermally stable interphases and demonstrates non‐flammability, suppressing heat accumulation for safer, high‐performance lithium‐ion batteries. ABSTRACT An asymmetric sulfonate‐based linear solvent, 2,2,2‐trifluoromethyl mesylate (FMS), is designed and used as the primary solvent in liquid electrolytes to enhance ...
