Effective Fire Extinguishing Systems for Lithium-ion Battery
The fire extinguishing agent includes water, water mist, foam, dry powder, and carbon dioxide. Among the various agents investigated, water and foam were the most effective by rapidly (<20 s) reducing the temperature of the cell and exstinguishing the fire. Water mist appeared less effective.

Lithium-ion batteries (LIBs) are widely used in electrochemical energy storage and in other fields. However, LIBs are prone to thermal runaway (TR) under abusive conditions, which may lead to fires and even explosion accidents. Given the severity of TR hazards for LIBs, early warning and fire extinguishing technologies for battery TR are …

Preparation and characterization of fire-extinguishing efficiency of novel gel-protein foam …
The new gel-protein foam exhibiting the optimal fire extinguishing efficiency is Formula I, which showed excellent foam stability and water retention capacity due to the presence of gel particles. The average size and water loss ratio of this formulation are 126.46 μm and 30.6%, respectively, compared to 273.24 μm and 44.1% for FFFP.

Firefighting Foams Explained: Action, Expansion and Application
Fire-fighting foam acts in two phases, insluation and cooling. Insulation stops the airflow and prevents the combustible from evaporating, taking away the oxidising agent. Cooling removes or decreases the energy that combustion requires as the water in the bubbles decants and evaporates. Low, Medium and High Expansion.
