The LithiumSafe™ Battery Bag

The LithiumSafe™ Battery Bag is a fire containment bag designed for spare lithium batteries and portable electronic devices (PED) carrying them.

The unique configuration of the Lithium safety bag consists of high temperature insulation & fire resisting materials that are able to withstand the explosive release of energy and cell combustion, as a result of a lithium ion thermal runaway.

Intensively tested and highly customizable to any size or color.

The LithiumSafe™ Kit, consisting of 1 x LithiumSafe™ Battery Bag and 1 x pair of LithiumSafe™ Gloves. Part # LSKT4744

 

First Aviation grade Fire Containment Bag on the market

Installed on board of +1000 aircraft

Preferred solution by major aviation companies

Outstanding battery fire insulation performance

All the materials that are used are non-combustible and can withstand continuous temperatures up to 1100 C (2012 °F) The temperature of a Lithium battery fire can easily reaches 600 – 1000 °C (1112 – 1832 °F) In addition to the high temperature resistance, the thermal conductivity of the insulation material is extremely low, allowing the use of minimal material thickness. In particular at high temperatures, the material far exceeds the insulation effect of alternative insulation materials. The low rising of the thermal conductivity with temperature increase and minimal shrinkage at maximum temperature is also advantageous for the LithiumSafe containment bag. The material is shock resistant; it tolerates fast heating and cooling cycles for a long period of time, which is ideal in the event of a thermal runaway.

Next Generation LithiumSafe™ PED Kit - UL5800 Compliant

We are pleased to introduce a new generation of LithiumSafe™ fire containment solutions engineered to meet the requirements of UL5800, an emerging standard for Personal Electronic Device (PED) fire containment in aviation.

This new and rigorous testing protocol simulates an ultra worst-case scenario of cylindrical 18650 type lithium-ion battery cells going into full thermal runaway at a 100% state of charge. Besides the extreme scenario, the standards requires zero smoke emission throughout the test cycle.

Although UL5800 sets a new benchmark for PED fire safety, it is not yet widely adopted by airlines globally. The primary reason: smoke emission onboard is manageable under existing safety protocols. Cabin crews are trained to deploy the PED containment kit, stow it in a lavatory or safe area, and isolate the event. Smoke extraction systems or air refresh cycles further mitigate the impact.

LithiumSafe™ Smoke Containment Sleeve - UL5800 Compliant

The LithiumSafe™ Smoke Containment Sleeve (PN: LSSC6550) is a lightweight, compact, and foldable solution engineered to provide zero smoke emission during lithium-ion battery thermal runaway events. Designed for use in aviation and other high-risk environments, it offers robust secondary containment around the 17” fire containment bag from our LSKT1000 kit.

At the core of its sealing performance is a custom-developed industrial-grade gas-tight zipper, ensuring secure pressure retention and gas sealing under extreme conditions.

Because the sleeve is a separate component, it allows for greater operational flexibility—the fire bag can first be removed from the cabin, then inserted into the sleeve if smoke or off-gassing occurs. This modular approach reduces bulk during storage and simplifies onboard procedures.

Already using LithiumSafe™ Bags onboard? The Smoke Containment Sleeve is fully compatible with first-generation LithiumSafe Kits/Bags and can be added as an upgrade to eliminate any release of smoke—without replacing your existing equipment.

When in flight, our electronic devices could pose a danger to the flight crew’s safety if a thermal runaway were to occur. In order to eliminate this risk we have ensured all aircraft contain a set of LithiumSafe™ Battery Bag and Gloves. LithiumSafe was chosen because of the Quality and responsiveness of organization, and the ability to make the product exactly to our requirements.

FAQ

What is a lithium battery safety bag?

A lithium battery safety bag is designed to provide an additional layer of protection when storing, transporting or handling lithium-ion batteries. The LithiumSafe™ Battery Bag helps reduce heat transfer and contain fire-related hazards that may occur during a thermal runaway event.

Thermal runaway is a chain reaction inside a lithium-ion battery that causes a rapid increase in temperature. This can result in fire, smoke, cell venting and the release of hazardous gases. Thermal runaway may occur due to battery damage, manufacturing defects, overcharging or internal short circuits.
The LithiumSafe™ Battery Bag can be used for laptops, tablets, smartphones, cameras, power banks, e-cigarettes, smartwatches, battery packs and spare lithium-ion battery cells. Multiple bag sizes are available to accommodate different battery formats..
