Lithium-Ion Battery Extinguishers
The Lith-Ex AVD lithium-ion battery fire extinguishers can be identified by a green band. They are designed for fires involving lithium-ion batteries – examples of typical lithium-ion battery fires include:
- Mobile phones
- Power tools
- E-scooters and bikes
- Energy storage
Lith-Ex extinguishers are available in a range of sizes, from 500ml for smaller batteries like those in e-cigarettes, to 25 and 50-litre versions for large installations and energy storage facilities. The versatility and efficacy of these extinguishers means they are suitable for use in a range of environments including domestic, industrial, transport, waste, marine and energy storage settings.
Lith Ex Li-ion fire extinguishers, as they’re also known, are CE-certified. They contain a non-toxic compound called Aqueous Vermiculite Dispersion (AVD), and they’re suitable for enclosed spaces. It is important that lithium-ion battery fires are tackled as quickly as possible, as these extinguishers are most effective when the fire is in its fledgling stages.
What are Lithium-Ion Batteries?
Lithium-ion batteries are a type of rechargeable battery, and they’re used in everyday electronics like laptops and mobile phones. The reason they’re so widely used is that they provide the most energy amongst rechargeable batteries on the market – their main competitor is the nickel-metal hybrid battery (NiMH), but NiMH batteries lose 20% of their charge every month, compared to just 5% a month for lithium-ion batteries.
The energy density of lithium-ion batteries is far superior, too. Lithium-ion batteries can store 150 watt-hours of energy per kilogram, whereas NiMH batteries can store 100 watt-hours per kilogram. When coupled with the fact that lithium-ion batteries are lighter than other batteries, the winner becomes clear.
For all their strengths, lithium-ion batteries can be susceptible to fires, thanks to their vulnerability to extreme temperatures. A process called thermal runaway is often central to the cause of lithium-ion battery fires: when a battery cell fails, the temperature increases, which releases more energy and breaks more cells, causing further temperature increases. This chain reaction can reach temperatures of up to 400°C very quickly. That’s why, in environments where these batteries are heavily used, lithium-ion fire extinguishers are required.
