Honeywell acquires Li-ion Tamer to enhance fire safety in li-ion battery systems, expanding its Building Automation and detection technologies portfolio.
Honeywell has finalized the strategic acquisition of the Li-ion Tamer business from Nexceris, further expanding its Building Automation segment’s fire safety portfolio. Li-ion Tamer specializes in early off-gas detection technology for lithium-ion (li-ion) batteries, which plays a crucial role in identifying thermal runaway events before they escalate into full-blown fires. This acquisition builds on a five-year collaborative partnership between Honeywell and Nexceris aimed at improving the safety of battery energy storage systems.
With the global demand for li-ion batteries projected to increase more than 30% annually—potentially surpassing $400 billion by 2030—ensuring their safe operation has become paramount across various industries including renewable energy, electric vehicles, cloud infrastructure, and grid storage. Thermal runaway remains one of the greatest safety risks associated with li-ion batteries. When not detected early, these events can destroy entire systems.
Li-ion Tamer’s proprietary early warning system detects off-gas emissions that occur prior to thermal runaway. This advanced detection can offer up to 30 minutes of lead time, providing operators with a crucial window to take preventive action. The product has gained global trust and adoption among top battery original equipment manufacturers (OEMs), demonstrating its effectiveness and reliability in high-stakes environments.
Billal Hammoud, President and CEO of Honeywell’s Building Automation segment, emphasized the importance of this move, noting, “As lithium-ion battery adoption accelerates in data centers, EV charging stations, and grid-scale storage, the associated fire risk increases. Li-ion Tamer’s early warning technology has been transformative for our customers. Integrating this solution into our broader portfolio positions Honeywell as a leader in battery fire detection and prevention technologies.”
The acquisition includes a portfolio protected by over 30 global patents. These technologies will be incorporated into Honeywell’s Building Automation offerings, alongside its well-established life safety solutions such as the VESDA (Very Early Smoke Detection Apparatus) system and the Connected Life Safety Services hosted on the Honeywell Forge IoT platform. This synergy will allow Honeywell to deliver a comprehensive and connected suite of fire detection and life safety solutions to its customers.
This transaction is expected to be immediately accretive to Honeywell's financials. It aligns with Honeywell’s broader strategy to streamline its business and focus on high-growth, high-impact sectors. Since December 2023, the company has engaged in several strategic initiatives and acquisitions totaling $13.5 billion, including Access Solutions from Carrier Global, Civitanavi Systems, CAES Systems, the LNG business from Air Products, and Johnson Matthey’s Catalyst Technologies.
Additionally, Honeywell recently divested its Personal Protective Equipment business to Protective Industrial Products and announced plans to spin off its Aerospace Technologies and Solstice Advanced Materials businesses—efforts aimed at creating three independent, publicly traded industry leaders.
