South 8 Debuts its ArcticTM LiGas® Battery Electrolyte for Reliable, Safe Performance in Extreme Environments

South 8 Technologies, a developer of advanced lithium-ion batteries, has introduced its Arctic LiGas 18650 cell at the Advanced Automotive Battery Conference (AABC) in San Diego. The new 18650 battery cell utilizes South 8’s liquefied gas electrolyte, LiGas®, to reduce fire risk and deliver high performance in cold weather conditions.
The Arctic LiGas 18650 cell replaces the traditional flammable liquid electrolyte with South 8’s liquefied gas electrolyte, providing a safe and high-performance lithium-ion solution. South 8 is currently distributing Arctic LiGas cells to selected customers for use in various markets and applications, including defense, electric vehicles, stationary storage, and battery-powered industrial equipment.
According to a November 2023 report by Bloomberg New Energy Finance, battery demand across electric vehicles and stationary energy storage is expected to grow by 53% year-on-year, reaching 950 gigawatt-hours in 2023, and more than 5,800 gigawatt-hours in 2035. South 8’s Arctic LiGas is one of the lithium-ion battery innovations that will help cell manufacturers deliver safer and more capable solutions to this rapidly expanding global market.
“LiGas addresses serious lithium-ion pain points: fire risk and depleted energy at low temperatures,” said South 8 CEO Tom Stepien. “Arctic LiGas cells solve these ‘fire and ice’ problems by minimizing thermal propagation with a non-toxic blend of gases that dissipate harmlessly when punctured or overheated. Arctic cells have the industry’s lowest operating temperature, providing energy down to –60°C (-76°F). We are excited to help our customers safely and efficiently operate in new environments and applications.”
Jungwoo Lee, co-founder and Chief Technology Officer, added, “We are delighted to deliver Arctic LiGas cells to our customer base of battery manufacturers and end-users who are validating our unique technology. Through internal and third-party testing, LiGas consistently demonstrates boundary-pushing performance in extreme environments and conditions.”
