American energy solutions company South 8 Technologies and Australian partner 3ME Technology have signed a letter of intent to develop a next-generation lithium-ion battery for defense operations in the Arctic.
The collaboration aims to blend the California-based firm’s proprietary LiGas cell technology with the New South Wales counterpart’s in-house EdgeVOLT Cold Weather Variant storage system.
Alongside the innovative power device, the team plans to explore market opportunities in support of military tasks that need “reliable, ultra-safe, portable power in austere environments.”
The LiGas and EdgeVOLT Systems
South 8’s LiGas battery cell, to be supplied for the initiative at production scale, has the capacity to endure extreme temperatures between -60 and 60 degrees Celsius (-76 and 149 degrees Fahrenheit).
It is made of non-toxic and non-corrosive liquefied gas electrolytes that evaporate quickly if punctured to lessen the hazard.
Those features, combined with fast charging and low-cost chemistries, allow deployments for defense, aerospace, and other demanding environments.
Meanwhile, 3ME’s EdgeVOLT battery storage is built for charging and discharging at temperatures down to -60 degrees Celsius (-76 Fahrenheit), unlike conventional units that are vulnerable to energy loss in cold.
The equipment is integrated with the company’s flagship BladeNET data management system, which maintains consistent monitoring performance.
In addition to Arctic conditions, the EdgeVOLT can be fielded across maritime and mining works.
‘New Benchmark’
The consortium said that the venture highlights both organizations’ shared commitment to modernizing energy solutions “for the most demanding operating conditions across the ANZUS, AUKUS, and NATO alliances.”
“We are seeing a clear shift in defense posture toward operations in colder and more extreme environments,” said Justin Bain, CEO of 3ME Technology.
“Our EdgeVOLT systems are already supporting warfighters with deployable power where reliability is critical, and this collaboration with South 8 positions us to accelerate the development of an extreme cold‑weather battery capability that sets a new benchmark for safety and performance.”
