With over 30 global patents, Li-ion Tamer’s technology is trusted by battery OEMs and supports safety in fast-growing energy storage and data center sectors.
Honeywell has announced the acquisition of Li-ion Tamer from Nexceris, a move aimed at strengthening its fire safety portfolio within its Building Automation business. Li-ion Tamer is a market-leading off-gas detection solution that offers early warning against thermal runaway events in lithium-ion (li-ion) batteries. The acquisition builds on a five-year strategic partnership and is expected to be immediately accretive to Honeywell’s financials.
As the global demand for li-ion batteries continues to rise—projected to grow over 30% annually through 2030 and surpass $400 billion—battery safety is becoming critical across sectors such as renewable energy, EV infrastructure, and data centers. Thermal runaway events in battery systems can result in catastrophic fires. Li-ion Tamer’s early warning technology, which can detect battery off-gassing up to 30 minutes before a potential fire, is already deployed by leading battery OEMs worldwide.
“Li-ion Tamer’s early warning technology has been revolutionary for our customers over the last five years,” said Billal Hammoud, President and CEO of Honeywell Building Automation. “This acquisition positions Honeywell as a leader in battery fire prevention and expands our fire detection capabilities.”
The Li-ion Tamer product suite, protected by more than 30 global patents, will be integrated with Honeywell’s existing portfolio, including VESDA smoke detection systems and the Connected Life Safety Services platform hosted on Honeywell Forge. Together, these offerings aim to provide comprehensive, intelligent fire safety solutions for modern buildings and industrial facilities.
