Introducing The ARCTIC™ AE35 18650 Cell
South 8’s new ARCTIC™ 18650, the AE35, delivers critical reliability across the harshest environments, with industry-leading cold-weather operation.
The AE35 uses a proprietary LiGas (liquefied gas) electrolyte to enable reliable charge and discharge from −60 °C to +60 °C (−76 °F to +140 °F).
The cells and the proprietary LiGas electrolyte are produced at South 8’s San Diego facility, providing customers with a domestically manufactured battery cell and a defined pathway toward meeting applicable National Defense Authorization Act (NDAA) sourcing requirements once those rules are finalized.
Whether in freezing cold or intense heat, LiGas ensures safe, high-performance energy when and where it’s needed most.

South 8’s LiGas is a liquefied gas held under pressure, giving LiGas an ultra-low freezing point below –100 °C while Liquid Electrolyte weakens at 0 ˚C and freezes at -20 ˚C. This unique property ensures it stays fully functional even in the harshest of environments.
Technology that Delivers
LiGas
South 8 is redefining lithium-ion battery performance through bold innovation and breakthrough chemistry.
Our patented LiGas® technology, the world’s first liquefied gas electrolyte, replaces conventional liquid electrolyte in lithium-ion cells, unlocking new levels of performance, safety, and versatility in even the most demanding environments.
Available in two formats – as LiGas battery cells sold directly to customers, as well as a LiGas Electrolyte Injection System for cell manufacturers.
LiGas powers the next generation of mobility and energy by delivering when and where it matters most.
Single Shot Fill. Faster Formation.
LiGas Electrolyte Integration
Streamline your electrolyte fill with one precise gas injection—no soaking, no waiting. LiGas accelerates formation and simplifies production for cylindrical cell lines.
To integrate LiGas electrolyte into lithium-ion battery cells, South 8 has developed a proprietary gas injection system that seamlessly fits within standard cell manufacturing lines.
The LiGas injector delivers a precise dose of the liquefied gas under controlled pressure. Once sealed, the gas remains in a liquid state inside the cell, ensuring optimal ionic conductivity and system performance.
This streamlined process enables manufacturers to adopt LiGas technology without major retooling, accelerating the path to safer, higher-performing batteries across a wide range of cylindrical cell format sizes.
