Honeywell has acquired the Li-ion Tamer business from Nexceris, a leading off-gas detection technology designed to identify early signs of thermal runaway in lithium-ion (Li-ion) batteries. This strategic acquisition enhances Honeywell’s fire life safety offerings within its Building Automation segment and builds on a five-year collaboration with Nexceris aimed at advancing battery safety solutions. The transaction is expected to be immediately accretive to Honeywell’s financial performance.
With demand for Li-ion batteries projected to grow over 30% annually through 2030, reaching more than $400 billion, robust safety solutions have become vital across industries, from renewable energy and electric vehicles to data centers and cloud infrastructure. Thermal runaway events can severely damage entire systems, making early detection essential for preventing or minimizing catastrophic fires.
Li-ion Tamer’s technology detects battery off-gassing, an early indicator of thermal runaway, providing up to 30 minutes of warning before a potential fire. This critical lead time empowers operators to intervene proactively. Trusted by top battery OEMs worldwide, Li-ion Tamer has set a new benchmark in battery safety.
“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.”
The Li-ion Tamer product portfolio protected by over 30 global patents will be integrated into Honeywell’s Building Automation business. This integration enhances Honeywell’s ability to deliver a comprehensive suite of fire detection solutions, complementing its existing portfolio of advanced smoke detection and life safety technologies. These include VESDA, a leading-edge system that detects the earliest signs of fire, and Connected Life Safety Services, which operates on the Honeywell Forge IoT Platform to provide the intelligence, connectivity, and compliance needed for secure and efficient fire system management.
This acquisition comes on the heels of Honeywell’s recent announcement to spin off its Aerospace Technologies and Solstice Advanced Materials businesses, forming three independent, publicly listed companies with distinct growth strategies. Since December 2023, Honeywell has pursued several strategic initiatives to drive organic growth and streamline operations—executing approximately $13.5 billion in value-accretive acquisitions. These include Access Solutions from Carrier Global, Civitanavi Systems, CAES Systems, the LNG business from Air Products, Sundyne, and Johnson Matthey’s Catalyst Technologies. The company also finalized the divestiture of its Personal Protective Equipment business to Protective Industrial Products last month.
