South 8 Technologies has partnered with Australian firm 3ME Technology under a letter of intent to create a next-generation lithium-ion battery optimized for military use in Arctic conditions.
The collaboration will merge South 8’s LiGas cell innovation with 3ME’s EdgeVOLT Cold Weather Variant storage technology, targeting defense applications that demand safe, reliable, and portable power in extreme climates.
Advancing Cold-Climate Energy Storage
The LiGas cells, to be delivered at manufacturing scale, are capable of functioning in temperatures from -60 to 60 degrees Celsius. They employ liquefied gas electrolytes that are non-toxic and non-corrosive, designed to dissipate quickly if compromised, thereby enhancing operational safety.
With rapid charging performance and affordable chemical composition, the LiGas platform supports demanding use cases across defense and aerospace sectors.
3ME’s EdgeVOLT system, engineered for sub-zero performance, can efficiently charge and discharge at temperatures as low as -60 degrees Celsius — conditions where traditional batteries typically suffer significant capacity degradation. The system works in conjunction with 3ME’s BladeNET monitoring architecture to ensure stable and consistent performance.
In addition to Arctic deployments, the EdgeVOLT platform is suited for maritime applications and heavy industries such as mining.
