• What is thermal runaway and why is it dangerous?

Thermal runaway is a critical failure event in lithium-ion batteries where internal temperatures rapidly rise out of control. During this process, the battery releases hydrogen gas, followed by highly toxic hydrogen fluoride (HF) smoke, often resulting in an explosion within 1–3 seconds. Temperatures can exceed 1000°C, triggering cascading failures in nearby batteries and causing severe fire and facility damage.
Understanding lithium-ion battery fire risks and implementing purpose-built safety cabinets is essential for modern battery storage and charging environments.

• How does the Fire-resistant insulation work and what temperature can it withstand?

The Fire-resistant Insulation fully surrounds each battery compartment, functioning like a high-temperature industrial kiln. It is continuously rated for 1260–1430°C, effectively preventing extreme heat from transferring to the cabinet’s outer walls.
In the event of thermal runaway, Fire-resistant insulation helps protect surrounding infrastructure and reduces the risk of secondary fires, making it a critical feature in advanced lithium-ion battery cabinets.

• Why Is a Ventilation System Essential in Lithium-Ion Battery Cabinets?

The ventilation system The integrated ventilation system safely channels hydrogen gas and hydrogen fluoride fumes through flame arrestors and exhaust vents. Without proper ventilation, pressure buildup inside the cabinet could force doors open or create explosive conditions.
A dedicated ventilation system is essential for safe lithium-ion battery storage, charging compliance, and explosion risk mitigation.

• Can a Standard Flammable Goods Cabinet Be Used for Lithium-Ion Batteries?

No. Standard flammable goods cabinets are not designed to manage lithium-ion battery hazards. Risks such as thermal runaway, hydrogen gas release, and extreme explosion temperatures require specialized lithium-ion battery cabinets with advanced insulation and ventilation systems.
First-time buyers should always review lithium battery cabinet compliance standards before making a purchasing decision.

• What Happens If a Battery Explodes Inside the Cabinet?

Each compartment is individually insulated to contain explosions and prevent thermal runaway from spreading. The combination of Fire-resistant insulation and the ventilation system manages heat, pressure, and toxic gases, protecting your facility from secondary fires and structural damage.

• What IP Rating Do Your Large Li-Ion Battery Cabinets Have?

On the Heavy Duty lithium-ion battery cabinets, the external electrical fan switches are rated IP56, ensuring reliable performance in demanding industrial and outdoor conditions.

• Where do the batteries put?

Do not expose the batteries directly or continuously to high temperatures or heat sources, such as direct sunlight.

Store the batteries in a location structurally or spatially separate from other flammable materials if there is no automatic extinguishing system available: minimum distance 2.5 m
