Honeywell acquires Li-ion Tamer® lithium-ion battery monitoring technology from Nexceris for their use
In a significant move, Nexceris' Li-ion Tamer® lithium-ion battery monitoring solution has been acquired by Honeywell. This technology, originally developed and commercialized by Nexceris, is widely recognised as the industry-leading solution for detecting off-gas emissions that indicate and prevent thermal runaway events in lithium-ion batteries, significantly enhancing battery safety [1][2].
The acquisition marks a transition for Li-ion Tamer®, as it is now integrated into Honeywell’s fire life safety portfolio within its Building Automation business. This move signifies a shift from a partnership model to full ownership by Honeywell. The company aims to leverage this technology to expand its early gas detection and battery fire prevention capabilities, strengthening its leadership in fire detection for diverse markets such as electric vehicles and data centers [4][5].
The acquisition has several notable impacts:
- Li-ion Tamer® has amassed over 400 million hours of sensing worldwide, demonstrating proven reliability and broad adoption in energy storage applications [1][3].
- Honeywell envisions battery safety monitoring as a core infrastructure element, not just an add-on, and plans to offer more comprehensive fire safety solutions by integrating this technology fully [4].
- The acquisition allows Nexceris to concentrate on other advanced materials and energy market innovations while Honeywell capitalises on its global reach to scale Li-ion Tamer® [1].
Post-acquisition, Nexceris continues its mission of commercialization with a focus on cleaner energy production and enhanced safety. The company has a robust portfolio of innovations in catalyst, electric vehicles (EV), and electrochemical applications [6]. Nexceris' commercial brands, fuelcellmaterials and HeatPath Solutions, will continue to deploy products across various applications [7].
The transaction was facilitated by GreenFront Energy Partners serving as the exclusive financial advisor to Nexceris. The sale of Li-ion Tamer® does not mark the end of Nexceris' commercialization strategy, but rather a step forward in its mission [8].
Kyle Shen, President and CEO of Nexceris, expressed pride in the success of Li-ion Tamer®. However, Randall Stacy, Chief Commercial Officer and Managing Partner at Nexceris, did not make a statement in the provided text [9].
Li-ion Tamer® is the industry's premier technology for preventing thermal runaway events in lithium-ion (Li-ion) batteries, a concern that gained prominence following a catastrophic lithium-ion battery fire at a U.S. Navy shipyard [10]. The solution's sale to Honeywell signifies a significant step towards safer adoption of energy storage across various industries [1][4][5].
