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

Adv 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 ...

In Situ Generation of Gel Foam via Heat-Accelerated Calcium Ion Release From Nano-CaCO₃ for Lithium-Ion Battery Fire Suppression and Prevention. [PDF]

Adv Sci (Weinh)
We present a heat‐accelerated in situ crosslinking strategy to create an alginate gel foam for lithium‐ion battery fire suppression. At ambient temperature, the formulation maintains low viscosity for easy foam generation. After exposure to fire, δ‐gluconolactone hydrolysis accelerates, enabling rapid Ca2+ release from CaCO3 and rapid ionic ...

Fire-Safe Hierarchical Solid Polymer Electrolytes Enabled by Dual-Functional Microcapsules for Lithium Metal Batteries. [PDF]

Adv Sci (Weinh)
Dual‐functional fire‐safe microcapsules are integrated into hierarchical solid polymer electrolytes to provide sequential protection against thermal abuse. The ammonium hydrogen phytate‐modified shell forms a protective char barrier, while the thermally triggered release of perfluoro(2‐methyl‐3‐pentanone) actively suppresses combustion, enabling safer ...
