Honeywell has acquired the Li-ion Tamer business from Nexceris, strengthening its fire and life safety portfolio with a proven off-gas detection technology that identifies early signs of thermal runaway in lithium-ion batteries.
The acquisition, built on a five-year partnership with Nexceris, enhances Honeywell’s Building Automation segment and is expected to be immediately accretive.
As global demand for lithium-ion batteries surges, projected to exceed US$400bn by 2030, safety solutions like Li-ion Tamer are increasingly vital.
The technology detects off-gassing up to 30 minutes before thermal runaway, giving operators time to prevent fires and limit system damage. It is already trusted by major battery OEMs worldwide.
The acquisition brings more than 30 global patents into Honeywell’s ecosystem and will integrate with the company’s existing safety offerings, including VESDA early smoke detection and Connected Life Safety Services on the Honeywell Forge IoT platform.
This move complements Honeywell’s broader strategy of focused growth, portfolio simplification, and recent acquisitions totalling US$13.5bn.
"As lithium-ion battery use grows rapidly across data centers, EV infrastructure, and grid-scale energy storage, the risk of fire is increasing in parallel," said Billal Hammoud, president and CEO of Honeywell's Building Automation segment.
"Li-ion Tamer's early warning technology has been revolutionary for our customers and partners over the last five years. Building on our legacy partnership, the acquisition of this product suite will position Honeywell as a leader in early gas detection and battery fire prevention. We expect this tuck-in acquisition to further bolster growth of our fire detection business."
