Galvion, a provider of power, data, and soldier system technologies, has signed a Letter of Intent (LOI) with South 8 Technologies, an innovator in lithium-ion battery technology, to advance battery performance for defense applications.
The LOI establishes a framework for cooperative innovation, knowledge exchange, and field-focused testing, with a shared commitment to addressing the energy challenges faced by warfighters in increasingly harsh environments. The focus is on improving battery performance in extremely cold climates, particularly the Arctic and other cold-weather theaters, where current energy solutions face limitations.
The initial scope of work is driven by the urgent needs of defense customers in the US and Northern Europe, who require improved battery reliability in extreme temperatures. The collaboration will leverage South 8’s patented LiGas® cell technology and align the companies’ research and development capabilities. The goal is to demonstrate next-generation battery systems capable of operating reliably in conditions with sustained temperatures as low as -60 °C (-76°F).
Todd Stirtzinger, CEO of Galvion, stated, “We have spent over a decade driving innovations in power provision and management to provide solutions that can adapt to the ever-changing operational needs of the modern warfighter. Arctic readiness is a new reality and partnering with South 8 allows us to explore battery technology that is specifically engineered to cope better with the challenges of extreme cold environments.”
Stirtzinger also noted an opportunity to combine South 8’s LiGas cell technology with Galvion’s “field-proven SoloPack™ battery family” to “provide defense customers with energy solutions that further enhance resilience, reliability, and mission readiness in extreme environments.”
South 8 Technologies’ CEO, Jungwoo Lee, commented on the agreement, saying, “At South 8, we are redefining what is possible for lithium-ion performance in the harshest environments. This LOI with Galvion represents an exciting step toward enabling reliable energy storage in extreme cold applications where conventional batteries struggle. By integrating our LiGas cells, customers like Galvion can deliver unmatched performance and resilience, supporting critical missions in the world’s most demanding conditions.”
The companies will explore opportunities for joint development and commercialization of battery solutions that utilize the wide temperature discharging and recharging capabilities, as well as improved safety characteristics, of the South 8 LiGas cells.
