Explosion Proof Battery
What Are Explosion-Proof Batteries?
Explosion-proof lithium batteries are high-safety energy sources designed for use in classified hazardous locations. Typically built on lithiumpolymer (LiPo) chemistry, these batteries use stable, leakproof electrolytes and rugged casings. They incorporate features like sealed cell housings, flameproof (Ex-rated) enclosures and internal vents or safety valves. In effect, any spark or heat generated inside the pack is contained by the reinforced housing, so it cannot ignite the surrounding atmosphere.
To illustrate, KRL Power’s packs include multi-layer protection circuits (overcharge, over-discharge, shortcircuit and temperature cutoffs) plus redundant BMS components. They also feature built-in pressure relief valves that safely vent if internal pressure rises, preventing a catastrophic failure. By combining these design elements, explosionproof batteries prevent ignition risks even if an internal cell fault occurs.

KRL Power – Explosion-Proof Lithium Battery Supplier for Extreme Environments
KRL Power is a leading China-based lithium battery manufacturer (founded in 2002) specializing in high-safety battery systems. We offer custom lithium-polymer battery solutions engineered for the most hazardous environments. Our explosion-proof battery packs are designed with reinforced cells and protective electronics to eliminate ignition sources in flammable atmospheres. For example, industry sources explain that explosion-proof Libatteries are built with advanced structural protections, electronic safety circuits and pressureresistant enclosures to prevent thermal runaway, shortcircuit or impact events from causing explosions. This makes them ideal for Zone 1 and Zone 2 areas (such as mines, oilfields, and chemical plants) where ignitable gases or dust are present.

What is the explosion-proof technology of lithium battery?
It is made of high safety factor material, which can effectively prevent the explosion of the battery. The safety characteristic of explosion-proof lithium battery pack is its biggest characteristic. In order to ensure the safety of lithium battery, we usually design an explosion-proof valve on the battery shell, which can be destroyed in time when the pressure is too high, release the pressure inside the battery, and prevent the explosion of lithium battery pack in the case of thermal runaway.
What certifications do your explosion proof batteries meet?
Our batteries comply with GB3836-2010 / Exib IIB T4 standards, approved by China’s National Coal Safety Authority, and also meet IEC62133, UL1642, CE, and RoHS certifications—ideal for Zone I and Zone II applications.
What are the key safety mechanisms in your explosion proof batteries?
Safety features include short-circuit, overcharge, overdischarge, and temperature protection; reverse polarity and impact-resistant structures; and a built-in pressure relief valve that vents safely in case of abnormal internal pressure.
Can I customize the battery’s size, voltage, or structure for my application?
Yes. We offer full customization of cell size, voltage, casing, explosion-proof structure, and protection circuits to match your system’s housing, connectors, and power requirements.
