Battery Energy Storage


Battery Fire Suppression

Aero-K® / Stat-X® condensed aerosol fire suppression is a line protection solution for energy storage systems (ESS) and battery energy storage systems (BESS) applications. This includes in-building, containerized, and in-cabinet applications. Aero-K® / Stat-X® systems provide highly effective battery room fire protection.


A lithium-ion battery or li-ion battery is a type of rechargeable battery in which lithium ions move from the negative electrode to the positive electrode during discharge and back when charging.


The deep-seated nature of battery fires creates challenges relative to extinguishing for every extinguisher type.

Due to out-gassing before and during battery ignition, re-flash remains a possible hazard.
Unlike gas systems operating under high pressure that seek exit from the hazard area,
Aero-K® / Stat-X® aerosol functions at low pressure and stays within the environment to deliver continual storage battery fire protection.

Gas systems will exit the hazard area through any openings. The Aero-K® / Stat-X® aerosol keeps its buoyancy and enables openings which are not closable as opposed to the rapid exit of gas in high pressure gas systems.


Aero-K® / Stat-X® state-of-the-art fire suppression technology delivers the most compact, lightest, and highly economical fire quenching solution. Our stainless steel, hermetically sealed, and exceptionally rugged canister – the Aero-K® / Stat-X® generator – contains a solid and stable compound. When a fire occurs, these Aero-K® / Stat-X® canisters automatically dispense propellant inert gases and ultra-fine particles which effectively put out fires utilizing smaller quantity of agent in terms of mass than any other type of standard fire extinguishing system.


Battery Fire Protection

Aero-K® / Stat-X® fixed systems are utilized in various applications in a number of different industries including energy supply and energy storage. The potential hazard posed by lithium-ion batteries is present in these industries, which can result in an exceptionally difficult fire to control and quench due to several issues:

For example:

  • An explosion risk is present due to exposure to short-circuits or heat in the batteries
  • Powerful reactions or toxicity may result from the remaining residues after combustion
  • Lithium batteries burn in an uncommon manner compared to other batteries
  • Increasing combustion gases ignite items in storage at higher levels
  • A high potential of ignition is related to the released electrolyte as a result of heat exposure
  • Fire penetration to the underside of the ceiling may occur within only minutes
  • Beyond the operational disruption involved, a fire often causes environmental damage and results in a complete write-off
  • There is limited access available for firefighting as a result of the density and height of stored items
  • Soot and smoke contaminate other items in storage nearby

Some of the benefits of the Aero-K® / Stat-X® fixed systems involving storage battery fire protection include:

  • Keeps good availability and delivery capability with no interruptions
  • Prevents the dynamic propagation of fires as a result of ignition with neighboring, closely packed batteries
  • No damage to the systems and goods by soot, fire, or the water applied to quench the fire
  • Provides continual and permanent fire safety without any restrictions on building use, staff movements, or altering the warehouse equipment, goods, and flow of goods


The Aero-K® / Stat-X® aerosol extinguishing product was tested for efficacy in putting out Li-ion battery fires. It was found that the Aero-K® / Stat-X® agent successfully extinguished single and double cell battery fires. This testing was conducted in parallel with a large battery fire testing program. Fireaway Inc. contracted with DNV GL for testing to have its Aero-K® / Stat-X® product line included in the program.

The following conclusions can be made from testing of Aero-K® / Stat-X® aerosol fire suppression system.

  • Aero-K® / Stat-X® can put out a Li-ion battery fire.
  • Residual Aero-K® / Stat-X® aerosol in the hazard will prevent a re-flash of the fire.
  • Aero-K® / Stat-X® can reduce oxygen in an enclosed environment during a battery fire. Our DNV-GL FA test for O2 levels that shows 18% and no drop.
  • Due to the deep-seated nature of a stacked battery fire, the Aero-K® / Stat-X® extinguisher removed heat from the interior of the cells more slowly than the exterior.
  • The residence time of gases and aerosols during Aero-K® / Stat-X® deployment is a function of when the atmosphere is ventilated.


  • No need for an airtight hazard area. And closable openings are permitted based on the calculations.
  • Residual Aero-K® / Stat-X® present after discharge in hazard areas prevents re-flashes which are common with lithium-ion battery fires, enhancing battery room fire protection.
  • Aero-K® / Stat-X® systems do not take up important floor space within the hazard since they are bracket mounted on the walls or ceiling within the hazard.
  • No piping or manifold is required, decreasing material and installation labor costs
  • Hydrostatic testing and cylinder weighing are not required.
  • Possesses a 10-year operational service life
