As lithium-ion batteries power our modern world—from electric vehicles and smartphones to large-scale energy storage systems—they bring with them a unique and severe fire risk. Traditional fire extinguishers often fall short against the intense, self-sustaining chemical fires that lithium batteries can produce. For businesses, facility managers, and safety officers, understanding and investing in the right lithium battery fire extinguisher is no longer a niche concern but a critical component of modern fire safety protocols.
At FiresafePlus, we are at the forefront of this challenge, providing cutting-edge fire safety solutions to protect against emerging risks. This guide explores why lithium battery fires are so dangerous and what you need to know to combat them effectively.
Why Lithium Battery Fires Are a Unique Challenge
Lithium-ion battery fires are classified as Class B fires (flammable liquids) but behave in a far more complex way due to a process called “thermal runaway.”
This is a chain reaction within a battery cell where overheating leads to a release of energy, which causes further overheating in adjacent cells. It results in:
-
Extreme Temperatures: Fires can exceed 1000°C .
-
Rapid Re-ignition: The fire can spontaneously restart even after it appears to be out.
-
Toxic Fumes: The burning process releases a cocktail of flammable and toxic gases.
-
Difficulty in Extinguishment: Simply smothering the fire or cooling the surface is often insufficient, as the reaction continues internally.
Standard dry powder (ABC) or CO2 extinguishers may temporarily suppress visible flames, but they often fail to penetrate and cool the battery pack’s core, making re-ignition a significant risk. This gap in safety has spurred the development of a new generation of fire suppression technologies.
Next-Generation Solutions: How Modern Lithium Battery Fire Extinguishers Work
The latest firefighting agents are specifically engineered to tackle the root causes of thermal runaway. The key is not just to smother the flames, but to cool the battery cells rapidly and continuously to stop the chain reaction. Recent advancements highlight several effective approaches:
1. AVD (Aqueous Vermiculite Dispersion) Fire Extinguishers
AVD extinguishers use a water-based vermiculite dispersion as the extinguishing agent . When deployed, this agent forms a cooling and insulating layer that helps to penetrate and prevent the intense heat of a lithium battery fire, making it more effective than traditional agents .
Market Insight: The global AVD fire extinguisher market was valued at approximately $57 million in 2024 and is projected to grow at a 7.3% CAGR to $87 million by 2031, reflecting the rising demand for these specialized solutions .
2. Fluorine-Free Firefighting Foams (FFF)
Environmental and health concerns around PFAS chemicals in traditional AFFF foams have driven innovation in “green” alternatives. New PFAS-free foams have been proven effective against lithium battery fires.
-
A Recent Breakthrough: In October 2025, a product named FIREBULL AB, a fluorine-free foam, successfully met the performance requirements of the NTA 8133:2021 standard for extinguishing lithium-ion battery fires . This standard requires agents to rapidly extinguish flames, prevent re-ignition for 20 minutes, and preserve some battery cell functionality .
3. Compressed Air Foam Systems (CAFS) and Specialized Agents
Combining specialized foams with compressed air systems creates a highly effective, blanketing foam that cools and suffocates the fire efficiently.
-
Chinese research teams have recently developed a new generation of intelligent, environmentally friendly compressed air foam technology. This system uses a composite, highly stable micro-foam lithium battery extinguishing agent that is non-toxic, efficiently cools, and can absorb smoke and hazardous gases .
-
Another company, Full Circle Lithium, is expanding its U.S. distribution network for its FCL-X™ lithium battery extinguishing products, targeting first responders, EV sectors, and waste management facilities where battery fires are a growing concern .
Choosing the Right Lithium Battery Fire Extinguisher
When selecting an extinguisher, look for models that have been tested against internationally recognized standards like NTA 8133 . Key features to consider include:
-
High Cooling Capacity: The primary mechanism must be deep, rapid cooling.
-
Prevention of Re-ignition: The agent should provide a lasting effect to stop thermal runaway.
-
Non-Toxic and Eco-Friendly: PFAS-free and non-hazardous formulations protect both responders and the environment .
-
Third-Party Certification: Always verify independent test results and certifications.
Where Are Lithium Battery Fire Extinguishers Critical?
The application for these specialized extinguishers is broad and growing:
-
Electric Vehicle (EV) Showrooms & Repair Shops
-
Battery Manufacturing and Storage Facilities
-
E-Mobility Hubs (e-scooter/bike charging stations)
-
Data Centers and Server Rooms
-
Waste Management and Recycling Centers
-
Residential and Commercial Buildings with large battery-based backup systems
