90 minutes’ fire protection for safe storage of lithium ion batteries.

As technology develops, so too do its applications. One such example of this development is the rechargeable lithium ion battery – once seen as a potential alternative to oil power, this powerhouse battery is now present in all workplaces in a variety of guises, from smaller items like phones, computers and portable tools, all the way to larger units such as electric vehicles.

It has taken 50 years for the lithium ion battery to realise its unique potential across the marketplace. After all this time however, the lithium ion battery is not yet without risk.

Lithium ion batteries pose fire and safety risks when stored improperly - learn more about the best storage solutions for these battery types.


Due to the nature of the electrolyte used in these battery types, there is an ever-present risk of fire and thermal runaway. Thermal runaway refers to the chain reaction that occurs when the temperature within a battery cell reaches a high enough point to cause a chemical reaction – this reaction burns extremely hot, and is nearly impossible to stop once it begins.

Additionally, if a battery is damaged, overloaded, or overheated, the risk of fire increases. As a result, great care should be taken when storing these batteries, particularly in larger quantities.

Lithium ion batteries stored at freezing or very high temperatures will see a loss of battery capacity – this can also create issues if the battery is used, as the battery will lack the level of structural integrity required to operate without risk.

Storage Solutions:

As care should be taken when storing lithium ion batteries, our team at Safety Storage have been working on developing a range of Fire-Protected Lithium Ion Battery Stores and Cabinets. These stores and cabinets offer 90 minutes of fire protection (in accordance with BS476 part 22), heavy duty welded steel construction with secure lockable doors, and self-sealing vents allowing the safe dispersal of highly flammable vapours.

The units are also customisable – allowing for additional options including adjustable shelving, lighting, temperature controls, and fire detection & suppression.

As the electrolyte used in lithium ion batteries has a low flashpoint, our team will ensure that any additional electrical equipment installed in the stores and cabinets also matches Atex Standards.

All units are provided fully assembled to your required specifications, and can be located indoors or outdoors with security signage fitted as standard.
