Which fire protection solution is suitable for a lithium-ion battery?

Die geeignete Lösung hängt von Batteriegröße, Energieinhalt, Battery Condition, Anwendung und Schutzziel ab. Für Elektrofahrzeuge und große Batteriesysteme kommen häufig Brandbegrenzungsdecken oder passgenaue Brandschutzhauben zum Einsatz. Für kleinere Akkus eignen sich je nach Anwendung Brandschutztaschen oder stationäre Lagerlösungen. Für Transport und Rücknahme können zusätzlich zugelassene Gefahrgutverpackungen erforderlich sein.

What is thermal runaway in lithium-ion batteries?

Thermal runaway is a self-accelerating thermal reaction within a battery cell. Within a short period of time, high temperatures, reaction gases, pressure pulses, flames and hot particles can be generated. Depending on the battery system, the event may propagate to additional cells.

Does a fire containment blanket extinguish a lithium-ion battery fire?

With lithium-ion batteries, conventional fire smothering is not the primary objective. Thermal runaway may continue due to internal chemical reactions. An appropriate fire containment blanket therefore primarily serves to contain the fire event, reduce flame spread and protect the surrounding area.

What temperatures can occur during lithium-ion battery fires?

Die thermische Belastung hängt stark von Zellchemie, Batteriegröße und Ereignisverlauf ab. Für besonders anspruchsvolle Anwendungen verwendet Fingerhuth SiO₂-Silikatgewebe mit Continuous temperature resistancekeit up to 1,200 °C und kurzzeitiger Spitzenbelastbarkeit bis 1.600 °C.

Which fire protection solutions are available for electric vehicles and parking garages?

For electric vehicles, solutions include in particular fire containment blankets in accordance with DIN SPEC 91489. Typical locations include parking garages, underground car parks, charging infrastructure, workshops, vehicle fleets, dealerships and public facilities. Deployment should be integrated into an operational response and safety concept.

Are fire protection solutions available for HV batteries in production and logistics?

Yes. For complete HV and traction batteries, we offer fire containment blankets and custom-fit fire protection covers. These can be adapted to the battery size, transport rack, production process or storage concept.

Does Fingerhuth also offer custom battery fire protection systems?

Yes. Fingerhuth develops custom textile fire protection systems for industrial applications. This includes material selection, engineering design, prototyping, custom dimensions and reproducible series production at our engineering and manufacturing site in Germany.

Which materials are used for battery fire protection systems?

Depending on the temperature and performance requirements, SiO₂ silica fabrics, high-temperature glass fabrics, thermal insulation materials, as well as functional coatings and finishes are used. The complete material and construction design of the respective system is always decisive.

Which solution is suitable for the take-back and transport of used lithium-ion batteries?

Für Rücknahme- und Transportprozesse muss zunächst der tatsächliche Battery Condition bewertet werden. Je nach Transportfall gelten unterschiedliche Gefahrgutvorschriften. Der SECON KMB Gefahrgutbehälter ist für definierte ADR-Verpackungsanweisungen ausgelegt und eignet sich unter anderem für professionelle Rücknahme-, Service- und Recyclingprozesse.

Fire Protection Solutions for Lithium-Ion Batteries & E-Mobility

BATTERY FIRE PROTECTION · SYSTEM SOLUTIONS

Lithium-Ion Battery Fire Protection Starts with the Specific Risk Scenario

Lithium-ion batteries are used today in electric vehicles, industrial trucks, machinery, power tools, mobile devices, energy systems and numerous industrial applications. As energy density increases, so do the requirements for prevention, fire containment, storage, transport and the safe handling of damaged or abnormal battery systems.

Fingerhuth engineers and manufactures textile high-temperature and fire protection solutions for different battery sizes, process stages and protection objectives. Our portfolio ranges from fire containment blankets for electric vehicles and HV batteries to fire protection covers for batteries and logistics units, as well as fire protection bags, dangerous goods containers and custom-engineered solutions.

The maximum temperature resistance of a material alone is not decisive. A robust safety concept must also consider battery condition, energy content, reaction gases, pressure development, particle release, mechanical loads, installation conditions and the actual protection objective.

FIRE PROTECTION SYSTEMS · PRODUCT PORTFOLIO

Fire Protection Solutions for Your Application

The appropriate protection solution depends on more than battery size or temperature exposure. We support you in selecting the right fire protection system and, where required, develop custom solutions for specific requirements.

SELECTION GUIDE · BATTERY FIRE PROTECTION

Which Fire Protection Solution Is Suitable for Your Lithium-Ion Battery?

A battery fire protection system should not be selected solely on the basis of a temperature rating. The decisive factors are the event scenario being considered, the amount of stored energy and the protection objective to be achieved.

The following criteria provide a technical basis for the preliminary selection of an appropriate solution.

01 RISK ASSESSMENT

Battery Condition

New, used, mechanically damaged, deeply discharged, abnormal or already thermally reacting batteries impose different requirements on handling, storage, transport and fire containment.

02 ENERGY CONTENT

Battery Size and Stored Energy

A single power-tool battery behaves fundamentally differently during an incident than an HV traction battery. Energy content, cell count and battery architecture influence temperature, fire duration and the potential volume of reaction gases.

03 PROTECTION OBJECTIVE

Contain, Shield or Transport Safely

Depending on the application, the objective may be spatial fire containment, protection of adjacent goods, thermal shielding, safe temporary storage or compliant dangerous goods packaging.

04 THERMAL RUNAWAY

Reaction Gases, Pressure and Particle Release

Thermal runaway involves more than heat and flames. Hot reaction gases, pressure pulses, jet flames and burning particles must also be considered when designing the protection system.

05 PROCESS ENVIRONMENT

Stationary or Mobile Use

Production lines, workshops, warehouses, service vehicles, parking garages and take-back points impose different requirements on space, handling, accessibility and system integration.

06 DEPLOYMENT CONCEPT

Preventive or Incident Response

Some systems are positioned preventively around a battery or logistics unit, while others are deployed only during a fire incident. Response time, personnel, accessibility and operational procedures must therefore be considered during product selection.

APPLICATIONS · INDUSTRY · INFRASTRUCTURE

Lithium-Ion Battery Fire Protection Throughout the Entire Battery Lifecycle

Lithium-ion batteries are now part of a wide range of industrial and commercial processes – from production and use to service, take-back, recycling and disposal. Accordingly, requirements for fire prevention, fire containment, safe storage and thermal shielding vary significantly.
