Insights

Technology Industry Analyst

Honeywell strategically acquires Li-ion Tamer® technology, strengthening its position in the growing battery safety monitoring market.

This acquisition represents a strategic enhancement to Honeywell's industrial safety portfolio by adding a proven lithium-ion battery monitoring solution. Li-ion Tamer® technology addresses a critical safety concern in energy storage systems by detecting potential thermal runaway events—catastrophic battery failures that can lead to fires—before they occur.

The technology originated from investigating a real-world disaster at a U.S. Navy shipyard, giving it practical credibility. With over 400 million hours of sensing already logged, Honeywell acquires not just technology but validated market experience.

This move strengthens Honeywell's Building Automation business at a pivotal time. As commercial and industrial facilities increasingly install energy storage systems, comprehensive safety monitoring becomes essential. The acquisition creates natural synergies with Honeywell's existing fire safety systems, potentially enabling integrated solutions for customers already using their building management platforms.

The deal builds upon a five-year partnership between the companies, suggesting a smooth integration path with minimal operational disruption. For Honeywell, this represents a focused expansion in a growing market segment driven by safety regulations, insurance requirements, and risk management considerations.

As lithium-ion batteries proliferate across grid storage, data centers, commercial buildings, and industrial applications, this acquisition positions Honeywell to capitalize on the corresponding demand for safety systems—a market with strong tailwinds as renewable energy adoption accelerates globally.

LEWIS CENTER, Ohio, July 15, 2025 /PRNewswire/ -- Nexceris, a leader in clean energy innovation, has sold its Li-ion Tamer® off-gas monitoring solution to Honeywell (NASDAQ: HON). Li-ion Tamer® is the industry's premier technology for preventing thermal runaway events in lithium-ion (Li-ion) batteries.

This strategic transaction enables Nexceris to focus on related breakthrough technologies across numerous energy markets through advanced materials and component-level products. It also allows Li-ion Tamer® as part of Honeywell's leading fire life safety portfolio within its Building Automation business. Building on its existing partnership with Honeywell, the sale also highlights Nexceris' strategy to commercialize technology in packaged products that are ultimately licensed or acquired by industrial partners.

"I am proud of what Li-ion Tamer® has become," said Kyle Shen, President and CEO of Nexceris. "This milestone reflects the dedication of our team and how Nexceris can transform technology ideas into global products. I want to thank all the Nexceris team members and partners who contributed to building Li-ion Tamer® to be a solution that makes energy storage safer all over the world."

Nexceris first recognized the need for lithium-ion safety monitoring solutions following a catastrophic lithium-ion battery fire at a U.S. Navy shipyard. Upon uncovering the root cause of the battery fire, Nexceris developed a durable detection solution, laying the groundwork for Li-ion Tamer®.  Once the technology was commercialized, Nexceris partnered with Honeywell over the past five years to sell Li-ion Tamer® worldwide to energy storage applications, resulting in more than 400 million hours of sensing to date. 

"This sale validates Nexceris' mission of commercialization through collaboration," said Randall Stacy, Chief Commercial Officer and Managing Partner at Nexceris. "Nexceris has a robust portfolio of innovations designed to enable greater efficiency, cleaner energy production, and enhanced safety. Our team is excited about our ability to impact clean energy in both the renewable and fossil fuel industries."

Looking ahead, Nexceris intends to deploy products across catalyst, electric vehicles (EV), and electrochemical applications through its commercial brands fuelcellmaterials and HeatPath Solutions.  Nexceris' collaborative model combines client technology with the company's scientific and engineering expertise, helping accelerate commercialization and deliver measurable results.

GreenFront Energy Partners served as the exclusive financial advisor to Nexceris for this transaction.
