Custom-made fire blankets for lithium batteries: fire protection

Custom fire-resistant blankets for lithium batteries are a passive protection solution designed to help control the consequences of a fire involving these energy storage systems.

The growth of electric mobility and the presence of batteries in industrial facilities, charging areas and storage spaces make it necessary to implement specific measures against thermal risks. When a lithium battery enters a thermal runaway process, it can generate extremely high temperatures, gases, projectiles and intense flames.

In these situations, a fire-resistant blanket can physically isolate the fire source and reduce its impact on nearby batteries, equipment or materials. Its use should always form part of established safety procedures and be combined with the fire suppression or cooling systems предусмотренные for each facility.

WHAT IS THE FUNCTION OF A FIRE-RESISTANT BLANKET FOR LITHIUM BATTERIES?

The main function of a fire-resistant blanket is to establish a fire-resistant separation between the affected battery and its surroundings. During an incident, it helps contain flames and projectiles while reducing thermal exposure to nearby elements.

This protection is particularly relevant in facilities where several batteries, modules or pieces of equipment are located close to one another. In these situations, having a passive thermal protection solution can help manage the affected area while the established emergency procedures are being applied.

The blanket should not be considered a fire suppression system in itself. It is an additional protection measure incorporated into the safety strategy of each facility alongside the specific systems and procedures established for fire incidents.

CUSTOM FIRE-RESISTANT BLANKETS MANUFACTURED BY TEXFIRE

Texfire manufactures fire-resistant blankets for lithium batteries using high-temperature-resistant technical silica fabric. Each solution can be adapted to the dimensions of the battery or module and to the specific characteristics of the application.

The company has its own weaving facilities and an in-house technical sewing department in Barberà del Vallès. This production capability allows customised products to be developed rather than relying exclusively on standard formats.

Both small and large formats can be manufactured, making it possible to adapt the blankets to batteries, modules or work areas with specific dimensions and geometries. Custom manufacturing allows the blanket to be configured according to the available space and the requirements of each industrial environment.

FABRIC, SEAMS AND FEATURES DESIGNED FOR EASIER HANDLING

In addition to the fabric itself, the manufacturing process is an important aspect of a blanket intended to operate under demanding thermal conditions. Texfire uses steel-reinforced thread and specially designed high-durability seams to increase the overall strength of the product.

The blankets can also incorporate handles at the ends to facilitate handling and make deployment more practical. The ability to customise dimensions, construction and certain functional features makes it possible to develop a solution specifically suited to each application.

CAN FIRE-RESISTANT BLANKETS FOR BATTERIES BE REUSED?

Fire-resistant blankets for lithium batteries can be reused provided they remain intact after an intervention. Before using them again, the condition of the fabric, seams and handles must be checked.

If significant damage, punctures or substantial deterioration caused by severe exposure to fire are detected, the blanket should be replaced. Post-use inspection is therefore essential to determine whether it remains suitable for another intervention.

FREQUENTLY ASKED QUESTIONS ABOUT FIRE-RESISTANT BLANKETS FOR LITHIUM BATTERIES

What does a fire-resistant blanket do during a battery fire?

It helps physically contain flames and projectiles generated during the incident. At the same time, it reduces direct heat exposure to nearby batteries, equipment and materials.

Does a fire-resistant blanket replace fire suppression systems?

No. It is a passive thermal protection solution that should be used as a complement to the safety protocols and fire suppression or cooling systems established for each facility.

Can blankets be manufactured for batteries of different sizes?

Yes. Thanks to its own weaving facilities and technical sewing department, Texfire can manufacture small and large-format blankets adapted to the dimensions of the battery, module and work area.

When should a blanket be replaced after a fire?

It should be replaced if it has punctures, significant damage or substantial deterioration caused by the fire. If reuse is considered, the integrity of the fabric, seams and handles must first be checked.

THERMAL PROTECTION ADAPTED TO EACH APPLICATION

Incidents involving lithium batteries can create particularly demanding thermal conditions. Incorporating a fire-resistant blanket specifically designed for the application provides additional protection against flames, projectiles and heat exposure to nearby elements.

As a manufacturer specialised in fire-resistant technical fabrics and textile thermal protection solutions, Texfire combines technical silica fabric, reinforced construction and custom manufacturing to develop blankets adapted to different batteries, modules and industrial environments.
