Soteria Battery Innovation Group: Eliminating Lithium Battery Fires Takes a Village
Amidst the volatility associated with lithium-ion batteries, Brian Morin, CEO of Soteria Battery Innovation Group, puts forth a challenging proposition, “When our architecture is fully developed, one will be able to puncture the batteries, crush them, damage them and they will not catch fire, period.” Soteria’s revolutionary lithium cell architecture overcomes the drawbacks of traditional battery configurations, eliminating thermal instability. The company has redesigned two major components of the lithium-ion architecture: the separators that are housed between the electrodes and the conductors carrying the current. While Soteria’s separators offer greater thermal stability at higher temperatures, the company’s conductive foils—made out of metalized films—prevent high intensity current from flowing to the affected area, arresting the heating of the battery.
Recognizing that once company can’t do everything, Soteria is bringing an ingenious marketing approach to assist battery manufacturers by creating an industry consortium for the next generation of lithium cell technology.
The company is supporting active development with leading end users such as Mercedes Benz and NASA to make batteries safer, lighter, and cost-effective. Soteria is connecting the lithium ion and automotive supply chains through its ‘open innovation platform.’ “We brought together companies—from materials companies like DuPont and Teijin and equipment companies like Voith and Applied Materials to end users like NASA and Mercedes—to develop what was needed and come out with prototypes that can be commercialized,” adds Morin.
With our architecture in place, one can puncture our batteries, crush them, damage them and our batteries will not catch fire, period
One of the noteworthy merits of Soteria’s architecture is that it is compatible with every lithium-ion manufacturing technique and chemistry in existence. It is integrated in the architecture as a material substitute without capital or equipment changes, while offering state-of-the-art performance characteristics that are exceeded by none in the industry. “There are three crucial aspects that each battery OEM focuses on: safety, lighter weight, and lower cost. Currently, every competitor offers improvements to one of these aspects as a trade-off with the other two. Our unique value proposition is that we deliver all the three without compromise,” explains Morin.
Soteria’s proficiency is best highlighted through its collaborations with NASA, wherein safety carries paramount importance. NASA has initiated a program to advance the developments of Soteria’s architecture and prove it safe enough for space flight. These developments could potentially reinvent the lithium-ion batteries, allowing OEMs to develop products with improved performance characteristics, safer usability, and greater affordability.

Inventus Power Joins Soteria Battery Innovation Group
Inventus Power reported that it joined the Soteria Battery Innovation Group, a consortium of companies representing an ecosystem of developers and users of energy storage technology for a broad range of markets. Soteria’s separator (see image above) and current collector technologies aid in preventing an internal cell short circuit from escalating into thermal runaway. This technology is just one example of new safety innovations that the consortium wants to promote.
Inventus Power offers standard and custom battery pack designs and intrinsically safe technologies including supercapacitors and lithium, lithium-ion, NiMH, NiCad, solid-state, and sealed lead-acid batteries.
“As the energy density of lithium-ion batteries has increased, there has also been an increase in companies and industries that are adopting li-ion battery technology. Along with this increase in adoption rate, there have been seemingly daily announcements of safety incidents concerning li-ion batteries across various markets/applications,” Chris Turner, CTO of Inventus Power said. “As the global leader in advanced battery systems, we have a long-standing history of developing safe, high-quality and reliable power solutions for wide range of markets. Inventus Power supports the continued development of new safety technologies at the cell, battery pack and device level and we believe that the BIG consortium’s mission of zero lithium-ion battery-related safety events can be realized.”
“Inventus brings significant expertise to help our other consortium members integrate the Soteria architecture into battery packs adapted to specific applications and markets. We look forward to working closely together to optimize safety, weight and cost improvements for its customers’ and our consortium members’ benefits,” Brian Morin, CEO of Soteria BIG commented.
Both Soteria BIG and Inventus Power will exhibit their products and technologies at the International Battery Seminar in Ft. Lauderdale, Florida on March 25-28. Soteria is also holding its second member meeting on March 25th in which Mr. Turner will meet representatives from NASA, Mercedes-Benz, NIO, and Motorola Solutions for an end-user panel discussion of the technology.
