With a proven ability to detect off-gassing up to 30 minutes before a fire, the system offers a vital safety advantage – allowing proactive measures before an incident occurs. The technology is widely deployed by battery OEMs worldwide and protected by a portfolio of over 30 global patents.
Li-ion Tamer: Meeting the Growing Demand for Battery Safety
With lithium-ion battery demand projected to grow 30% annually and surpass $400 billion by 2030, Honeywell’s acquisition of Li-ion Tamer positions the company at the forefront of battery safety innovation.
“As lithium-ion battery use accelerates in mission-critical sectors like data centers, grid-scale energy storage, and EV charging, the risk of fire grows in parallel,” said Billal Hammoud, President and CEO of Honeywell Building Automation.
“Li-ion Tamer’s early warning detection has been a game-changer for our partners. Integrating this technology into our fire life safety suite will enable us to lead in battery fire prevention.”
Enhancing Honeywell’s Fire Detection Ecosystem
The integration of Li-ion Tamer complements Honeywell’s existing fire and life safety solutions, including VESDA – a high-sensitivity smoke detection system – and Connected Life Safety Services, powered by the Honeywell Forge IoT platform.
