FAQS

Lithium-ion batteries (sometimes abbreviated Li-ion batteries) are a secondary (rechargeable) battery where the lithium is only present in an ionic form in the electrolyte. Also included within the category of lithium-ion batteries are lithium polymer batteries. Lithium-ion batteries are generally used to power devices such as mobile telephones, laptop computers, tablets, power tools and e-bikes and e-scooters. 1. What are the various types of lithium batteries? Lithium batteries fall into two broad classifications: lithium metal batteries and lithium-ion batteries. Lithium metal batteries are generally non-rechargeable and contain metallic lithium. Lithium-ion batteries contain lithium which is only present in an ionic form in the electrolyte and are rechargeable. Within these two broad classifications there are many different chemistries. For example within lithium ion batteries there are lithium polymer, lithium iron phosphate (LiFePO4), lithium air to name a few. 2. What is the difference between a lithium cell and a lithium battery? A lithium cell is a single encased electrochemical unit consisting of one positive and one negative electrode that exhibits a voltage differential across the two terminals. A lithium battery is two or more cells electrically connected. A single cell battery is considered a cell and not a battery for the purposes of the limitations set out in the DGR. Units that are commonly referred to as “battery packs” or “power banks” having the primary function of providing a source of power to another piece of equipment are for the purposes of these Regulations treated as batteries. 3. How are component cells connected to form a battery? Cells in batteries may be connected in parallel, in series, or in a combination of the two. When cells are connected in series, the voltage of the battery increases but the capacity in ampere hours (Ah) does not change. By contrast, when cells are connected in parallel the capacity in ampere-hours of the battery (Ah) increases but the voltage stays the same. 4. How do I determine the watt-hour rating for a particular li-ion battery? The Watt-hour (Wh) rating is a measure by which lithium-ion batteries are regulated. lithium ion batteries manufactured after 31 December 2011 and Section IB and Section II lithium-ion batteries manufactured after 1 January 2009 are required to be marked with the Watt-hour rating on the outside case. You can also arrive at the number of Watt-hours your battery provides if you know the battery’s nominal voltage (V) and capacity in ampere-hours (Ah): Ah x V = Wh Note: If only the milliampere-hours (mAh) are marked on the battery then divide that number by 1000 to get ampere-hours (Ah) (i.e. 4400 mAh / 1000 = 4.4. Ah).

STATEMENT IN RESPONSE TO THE NFPA & FSRI JOINT NOTICE ON EV FIRE BLANKETS

IntroducƟon

We acknowledge the publicaƟon Ɵtled "Joint NoƟce Highlights PotenƟal Risk with Electric Vehicle FirefighƟng TacƟc Involving Fire Blankets" issued by the Fire ProtecƟon Research FoundaƟon (FPRF) and the Fire Safety Research InsƟtute (FSRI) on May 30, 2025. The findings contribute to the criƟcal and evolving dialogue around EV (electric vehicle) firefighƟng tacƟcs , an area where innovaƟon must proceed in parallel with evidence-based safety assessments. However, it is essenƟal to place these findings in the appropriate operaƟonal and technical context to avoid misinterpretaƟon or premature dismissal of fire blankets as a viable firefighƟng support tool when used correctly by trained professionals.

Acknowledging the Findings:

The noƟce appropriately emphasises two key risks:

1. Ongoing thermal runaway in EV baƩeries can conƟnue aŌer flame suppression. 2. Flammable gases released during thermal runaway can accumulate under fire blankets and pose a delayed igniƟon or explosion risk. These are real and important consideraƟons, but they do not consƟtute a blanket contraindicaƟon (no pun intended) to the use of fire blankets. Instead, they highlight the criƟcal importance of training, protocol, and situaƟonal awareness in EV fire incidents. EV fire blankets are not intended to stop baƩery thermal runaway or replace water-based suppression systems. Their role is targeted and specific: • To suppress open flames rapidly. • To control radiant heat to protect nearby vehicles, property, and responders. • To reduce formaƟon of smokes and toxic gases , providing safer air quality for occupants and firefighters. • To create tacƟcal Ɵme for firefighƟng personnel to assess, coordinate, and deploy addiƟonal suppression measures. A fire blanket serves as a passive fire protecƟon measure for baƩeries that are damaged or undergoing thermal runaway. Such baƩeries pose a latent fire hazard, as igniƟon may occur several hours or even days aŌer the iniƟal mechanical, electrical, or thermal stress event. Clarifying the Role and Limits of Fire Blankets

Fire blankets are a containment and control tool - not an exƟnguishment soluƟon.

Rebuƫng the Risk of Explosion from Gas AccumulaƟon

While the experimental findings are valid in controlled laboratory condiƟons, several key operaƟonal points must be considered: 1. The same risks of gas accumulaƟon exist in enclosed spaces , under vehicle bonnets, or in parking structures. This potenƟal risk is not unique to the use of fire blankets. Rather, it highlights the need for situaƟonal gas and pressure awareness , not avoidance of tools.

2. Trained personnel : Only trained responders can use the fire blanket, hence, Firechief Global provides guidelines and training for the safe use of the fire blankets. Our goal is to educate as to the tacƟcal use of blanket and correctly assess the benefits, risks and limitaƟon.

Support for ConƟnued Research

We fully support and encourage the conƟnued research by FPRF and FSRI. Their work is essenƟal in refining and validaƟng best pracƟces for emerging fire challenges. However, unƟl conclusive data confirms consistent explosion events across a wide range of real-world condiƟons, the recommendaƟon should not be to disconƟnue the use of fire blankets, but instead to adhere to safe blanket use.

Conclusion

Firechief ® LithShield EV fire blankets are specifically engineered for the miƟgaƟon of hazards associated with lithium-ion baƩery incidents, including thermal runaway and subsequent fire propagaƟon. The LithShield Tough blankets have been tested in accordance with, and passed, DIN SPEC 91489:2024-11, which replicates combusƟon scenarios representaƟve of EV baƩery fires. Report is available on request. EV fire blankets, when deployed by trained personnel , remain a valuable tacƟcal opƟon for managing specific risks associated with EV fires, especially in urban, confined, or high-exposure environments. The recent joint noƟce highlights a specific risk , not a universal failure, and should prompt refinement, not rejecƟon , of the tacƟc. We look forward to engaging construcƟvely with the NFPA, FSRI, and other stakeholders to ensure that the fire service community is empowered with both tools and knowledge to face the growing challenge of EV fires safely and effecƟvely.
