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.
Engineered for performance Advantage
LiGas Battery Cells
LiGas battery cells deliver mission-ready power for defense applications, engineered to perform in extreme environments from -60 °C to +60 °C. Utilizing our patented liquefied gas electrolyte, LiGas enhances safety, reliability, and thermal performance beyond conventional lithium-ion.
Ideal for use in applications such as soldier power and communication devices, flashlights, and drones, these cells offer rugged, high-performance energy storage for tactical, wearable, and autonomous platforms.
Available today in 18650 cylindrical format; contact us to sample in other cylindrical sizes.

LiGas Cells vs. Liquid Electrolyte Cells
Top Tier Competitor Cell Comparison
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.

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.
