South 8 Technologies product offering
Product offeringCore offering
South 8 Technologies develops and manufactures LiGas, the world's first liquefied gas electrolyte for lithium-ion batteries, which replaces conventional liquid electrolytes to enable operation from -60°C to +60°C with enhanced safety. The company sells finished LiGas battery cells in 18650 cylindrical format directly to defense, aerospace, and specialty customers, and separately offers a LiGas Electrolyte Injection System kit that allows cell manufacturers to integrate LiGas technology into their own cylindrical cell production lines. Manufacturing is based in San Diego, California, with planned expansion to 100 MWh of electrolyte and 2 MWh of cell production annually.
Product overview
South 8 Technologies offers LiGas, the world's first liquefied gas electrolyte platform for lithium-ion batteries, available in two distinct formats: (1) finished LiGas Battery Cells sold directly to customers in 18650 cylindrical format, and (2) the LiGas Electrolyte Injection System — a proprietary gas injection system and integration kit for cell manufacturers. The company's Arctic LiGas 18650 Cells represent a specialized sub-brand targeting extreme cold-weather defense applications. LiGas replaces conventional liquid electrolytes, unlocking enhanced performance, safety, and versatility across extreme temperature ranges from -60°C to +60°C.

Products and services
- LiGas Battery Cells Finished lithium-ion battery cells utilizing South 8's patented LiGas liquefied gas electrolyte, sold in 18650 cylindrical format to defense primes, system integrators, and aerospace customers. Cells deliver mission-ready power operating from -60°C to +60°C with enhanced safety via thermal fuse electrolyte evacuation.
- LiGas Electrolyte Injection System A proprietary gas injection system and LiGas electrolyte kit for cell manufacturers to integrate LiGas liquefied gas electrolyte into standard cylindrical lithium-ion battery production lines. The injector delivers precise doses of liquefied gas under controlled pressure, enabling LiGas adoption without major retooling.
- Arctic LiGas 18650 Cells Specialized variant of LiGas battery cells branded for extreme cold-weather and Arctic defense operations. These 18650 cells enable reliable discharge and recharge at temperatures as low as -60°C for soldier power, tactical electronics, and unmanned systems in cold environments.
Quantifiable outcome
- 2.4x longer flight time in cold conditions (7 min 41 sec vs 18 min 22 sec for LiGas)
- +3 more outcomes
