German motor vehicle inspection association (DEKRA) reported several kinds of water-based fire-extinguishing agents such as water, F-500 and a gelling agent used in extinguishing lithium-ion traction batteries fires. The flame of power LIBs was rapidly extinguished by 1% F-500 within merely 7 s.
Liu Y, Duan Q, Li K, Chen H, Wang Q (2018) Experimental study on fire extinguishing of large-capacity lithium-ion batteries by various fire extinguishing agents. Energy Storage Sci Technol 7:1105–1112
This research examined the flame retardant (FR) FPPN in 5 Ah lithium-ion battery (LIB) cells under large-scale conditions to assess its resilience under abusive scenarios such as nail penetration, external short-circuiting, overcharging, and thermal stress.
In addition to the flame retardant transformation of the battery itself, battery flame retardant can also be achieved by adding protection device outside the battery, such as wrapping a flame retardant shell outside the battery or installing an automatic fire extinguishing device, etc.
The mechanism of fire-extinguishing agent is mainly divided into isolation, smothering, cooling and chemical suppression. However, the fire triangle of battery is difficult to destroy, as the three elements of fire triangle can be provided by the battery itself. In addition, LIB fire is a complex fire with the characteristics discussed above.
Lithium metal battery (LMB) is regarded as one of the most promising high-energy energy storage systems. However, the high reactivity of lithium metal and the formation of lithium dendrites during battery operation have caused safety concerns. Herein, we present the design and synthesis of fire-extinguishing microcapsules to enhance LMB safety.

Boehmite-based Microcapsules as Flame-retardants for Lithium …
The fire extinguishment of a mixture of lithium-ion cathode and electrolyte is investigated based on the use of flame retardants. Four boehmite-based flame-retardants are embedded in the LiFePO 4 cathode including 0.95 μm AlOOH-L, 0.35 μm AlOOH-S, and their individual microcapsules. The microcapsules are denoted as en-AlOOH-L and en-AlOOH-S.
