Lithium-ION Risk Prevention System

The ANSUL® Lithium-Ion Risk Prevention System is designed to monitor lithium-ion batteries used in the energy storage market.  Early warning detection of off-gases/toxic vapours indicates when there is a malfunction within the battery cell, allowing action to be taken to help prevent thermal runway from occurring.  Thermal runaway can cause the failure of a single cell to propagate, creating a domino effect into adjacent cells, resulting in a catastrophic event.

Lithium-ion batteries are used in energy storage.

The ANSUL® Lithium-Ion Risk Prevention System – when combined with AUTOPULSE fire detection panels, ANSUL® INERGEN® Fire Suppression Systems or SAPPHIRE® Suppression Systems – identifies lithium-ion batteries that have off-gassed and provides the ability to help suppress fires by proactively activating alarms and releasing the fire suppression system.


The ANSUL® Lithium-Ion Risk Prevention System with a connected releasing panel and suppression system is particularly useful for early detection and suppression of fires in hazards where lithium-ion batteries are in use. Typical applications include lithium-ion energy storage systems, lithium-ion battery test chambers and lithium-ion battery assembly rooms.
