Electric vehicles, e-bikes, energy storage systems, and consumer electronics have transformed the way the world stores and uses energy. But the lithium-ion batteries powering this shift carry a fire risk that is fundamentally different from anything conventional fire safety was designed to handle. Lithium-ion battery fires burn hotter, behave less predictably, and are far harder to extinguish than most fire types that safety professionals have trained for. Understanding why this risk is growing, and what it takes to control it, is now essential for anyone operating in or around fire safety.
Across industries from logistics to maritime to recycling, the question is no longer whether lithium-ion battery fire risk applies, but how prepared the people and systems in place actually are. This article breaks down who is most exposed, what makes these fires so technically demanding, how regulation is shifting the landscape, and what modern suppression technology can do that conventional agents cannot.
Industries Most Exposed to Lithium-Ion Battery Fire Hazards
Lithium-ion battery fire risk is not confined to a single sector. It follows the technology, and that technology is now embedded across a wide range of industries, each with its own exposure profile.
Warehousing and logistics operations are among the most heavily exposed. The rise of e-commerce has placed large numbers of lithium-ion-powered devices, tools, and vehicles inside the same buildings, often alongside high-density racking systems that can accelerate fire spread. E-bikes and electric forklifts are now standard equipment in many facilities, and a single thermal runaway event in a charging area can escalate rapidly.
Energy storage installations present a concentrated risk. Grid-scale battery systems, commercial solar storage, and backup power units contain large numbers of battery cells in close proximity. If one cell enters thermal runaway, the heat it generates can cascade to neighbouring cells, turning a localised incident into a large-scale event that overwhelms standard suppression systems.
Maritime operators face a particularly serious challenge. Fires aboard vessels are dangerous in any circumstances, but a lithium-ion battery fire in an enclosed hull, far from shore-based emergency services, creates a scenario where suppression capability and response time are both severely constrained. The growing use of electric propulsion and onboard energy storage is pushing this risk higher.
Recycling facilities that process electronic waste, batteries, and end-of-life vehicles are exposed to damaged and degraded cells that are already at elevated risk of thermal instability. Mechanical damage during sorting or compaction can trigger thermal runaway without warning. EV charging infrastructure providers, building managers overseeing car parks with EV access, and industrial plant operators running battery-powered equipment all share comparable exposure. The common thread is that the energy density of lithium-ion technology creates a fire hazard that scales with adoption.
What Makes Lithium-Ion Battery Fires Uniquely Difficult to Suppress
The core challenge with lithium-ion battery fires is that the energy sustaining the incident can come from inside the battery cells themselves, not just from external fuel sources. This internal chemistry makes these fires behave in ways that conventional suppression agents are not designed to address.
When a lithium-ion cell is mechanically damaged, overcharged, or exposed to excessive heat, it can enter a condition known as thermal runaway. As the cell temperature rises, internal materials decompose, flammable gases are released, internal pressure builds, and the casing can rupture. Heat from one failing cell then transfers to adjacent cells, triggering a cascading sequence of failures across the battery pack. According to Anogas’s technical documentation, thermal runaway can produce temperatures exceeding 850 degrees Celsius.
Hazardous Gas Release
Alongside extreme heat, lithium-ion battery fires release a mixture of dangerous gases, including hydrogen, methane, and hydrogen fluoride. Hydrogen and methane increase flammability and explosion risk, while hydrogen fluoride is both toxic and corrosive. Critically, gas release can continue even after visible flames have been suppressed, meaning that a fire that appears to be out may still be generating hazardous conditions.
Re-ignition Risk
Re-ignition is one of the most serious operational challenges in battery fire suppression. Residual heat and ongoing chemical activity inside the battery can restart combustion long after initial flames are extinguished. Water alone, while effective at surface cooling, runs off quickly and does not maintain sustained contact with the heat source. This limits its ability to prevent the temperature from climbing again once application stops. Understanding how thermal runaway develops and propagates is a necessary starting point for selecting suppression technology that can actually terminate the incident rather than temporarily interrupt it.
How Tightening Regulations Are Reshaping Fire Suppression Requirements
Regulatory pressure is accelerating the shift away from conventional suppression agents, particularly those containing PFAS (per- and polyfluoroalkyl substances). These persistent synthetic chemicals have been widely used in firefighting foams because of their effectiveness, but their environmental and health consequences are now driving significant legislative action across Europe and beyond.
European regulation is actively phasing out PFAS-containing extinguishing agents. According to Anogas’s product documentation, Regulation (EU) 2025/1988 sets a trajectory towards a complete ban by 2031. For fire safety operators, distributors, and facility managers, this creates a practical deadline. Products and systems that currently rely on PFAS-based agents will need to be replaced, and the window to plan and implement that transition is narrowing.
At the same time, regulations governing the installation and management of lithium-ion battery systems are becoming more stringent. Building codes, insurance requirements, and industry standards increasingly specify that fire suppression systems in high-risk battery environments must demonstrate the ability to control thermal runaway, not simply extinguish surface flames. This raises the bar for what qualifies as adequate protection and pushes operators towards solutions with documented performance against battery-specific fire scenarios.
For distributors operating in the fire safety sector, the regulatory environment represents both a compliance challenge and a market opportunity. Products that are already PFAS-free and certified for lithium-ion battery applications are well positioned to meet demand that conventional agents cannot serve.
How Hydrogel Technology Addresses Lithium-Ion Battery Fire Risks
Addressing the full complexity of a lithium-ion battery fire requires more than a single suppression mechanism. Anogas Hydrogel is engineered to work across five simultaneous mechanisms that together target the heat, chemistry, gas release, and re-ignition risk that make these fires so difficult to control.
The foundation of how Hydrogel works is its temperature-sensitive gel formation. At ambient temperatures, Hydrogel is a low-viscosity liquid that can be applied through standard water-based systems. As it contacts heat, it transforms into a thicker, adhesive gel that clings to hot battery surfaces rather than running off. This sustained contact is what enables continuous cooling, unlike water alone, which loses contact quickly and allows temperatures to rebound.
Five Mechanisms Working Together
Rapid cooling and flame extinguishment come first. Hydrogel’s high water content absorbs heat quickly and lowers battery temperatures while the gel layer maintains persistent contact with the fire source. Thermal isolation follows, as the gel forms a physical barrier around affected cells that limits heat transfer to neighbouring cells and helps contain the fire within a defined area.
Gas suppression and neutralisation address the hazardous gases released during thermal runaway. Hydrogel reduces concentrations of flammable gases, restricts oxygen availability, and interacts with hydrogen fluoride to convert it into less harmful ionic components. This does not eliminate gas exposure entirely, but it meaningfully reduces the atmospheric hazards that emergency responders face.
Lithium-ion stabilisation is a mechanism specific to battery fires. Modified clay particles within Hydrogel penetrate damaged battery structures and bind reactive lithium ions, reducing chemical reactivity inside the battery and contributing to longer-term stabilisation after visible flames are extinguished. Finally, re-ignition prevention is maintained through the combination of sustained cooling, thermal insulation, reduced oxygen availability, and chemical stabilisation.
Hydrogel is composed of water and modified natural clay, contains zero PFAS, and is certified according to KIWA NTA 8133 for lithium-ion battery fire applications. It is fully interchangeable with water and can be used in existing water-based suppression infrastructure, reducing the integration cost for operators transitioning away from conventional agents. For facilities that need handheld capability, portable Hydrogel extinguishers are available for direct application, while larger installations can be served through fixed fire suppression systems using the same technology.
The Commercial Opportunity for Fire Safety Distributors
For fire safety distributors, the convergence of rising lithium-ion battery adoption, tightening PFAS regulation, and growing demand for certified battery-specific suppression creates a clearly defined market opportunity. The industries most exposed to battery fire risk are actively seeking products that can demonstrate genuine performance, not just compliance on paper.
What makes this opportunity particularly strong is the scarcity of credible alternatives. Most conventional agents were not designed with battery thermal runaway in mind, and PFAS-based foams face a regulatory phase-out that removes them from long-term consideration. A PFAS-free solution with documented multi-mechanism performance against lithium-ion battery fires occupies a position that very few products can claim.
Distributors who understand technical fire safety products and serve end markets in warehousing, maritime, EV infrastructure, or industrial operations are positioned to bring genuine added value to their customers by offering a solution that addresses a problem those customers are already concerned about. The Hydrogel product range is available in formats suited to both handheld and large-scale fixed-system applications, giving distributors the flexibility to serve different customer segments with a single technology platform.
The broader trend is clear: as lithium-ion batteries become more prevalent across more sectors, the demand for fire suppression solutions specifically engineered for battery fire risks will continue to grow. Distributors who establish expertise and supply capability in this area now are building a position in a market that is still in its early stages, with the regulatory tailwind of PFAS phase-out accelerating customer transition timelines. The combination of genuine product differentiation, environmental compliance, and growing end-market demand makes this one of the more compelling opportunities in the fire safety sector in 2026.
