explosion proof lithium battery

Explosion-proof Lithium Battery Solutions

Designed for high-risk environments such as oil & gas drilling, mining operations, petrochemical facilities, and confined hazardous spaces, LARGE explosion-proof lithium battery systems provide safe, stable, and certified power supply under extreme working conditions.

We specialize in custom explosion-proof battery system design, supported by:
  • Explosion-proof certification design (ATEX / IECEx / GB3836)
  • Multiple protection concepts: Ex i (Intrinsic Safety), Ex d (Flameproof), Ex m (Encapsulation)
  • Full lifecycle safety management BMS
  • Structural and thermal protection for high temperature, vibration, and harsh environments

We don’t supply standard batteries — we deliver customized explosion-proof battery solutions tailored to specific application scenarios.

Challenges in Hazardous Environments

In real-world industrial applications, companies face critical risks:

  • Thermal runaway under high temperature or abnormal conditions
  • Explosion risks in flammable gas or dust environments
  • Structural instability caused by vibration or impact
  • Complex certification procedures and compliance requirements
  • Diverse equipment needs, making battery selection difficult
