South 8 Technologies develops advanced lithium-ion battery technology through its innovative LiGas® electrolyte system. Founded in 2016 as a spin-out from UC San Diego, the company specializes in creating safer, more efficient battery solutions that perform effectively in extreme conditions. The company’s LiGas technology addresses common limitations in traditional lithium-ion batteries, including thermal safety concerns and performance issues in varying temperatures. Through continuous research and development, South 8 Technologies has established itself as a significant contributor to battery innovation, particularly in applications requiring reliable performance under challenging environmental conditions.
Battery Technology
The LiGas electrolyte technology represents South 8 Technologies’ primary innovation in the battery sector. This system uses liquefied gas electrolytes that remain stable under pressure and operate effectively across an extensive temperature range from -60°C to +60°C. The technology offers several distinct advantages over conventional liquid electrolytes:
- Enhanced Safety: LiGas significantly reduces fire risks associated with traditional lithium-ion batteries
- Improved Performance: The system enables faster charging capabilities and increased energy density
- Temperature Resilience: Batteries using LiGas maintain consistent performance in both extremely cold and hot environments
- Manufacturing Efficiency: The technology integrates with existing production processes, allowing for single-shot filling and rapid formation
The system’s compatibility with standard battery materials makes it particularly valuable for electric vehicles, underwater applications, aerospace, and defense sectors. This versatility, combined with its safety features, positions LiGas as a practical solution for advancing battery technology across multiple industries.
Recent Projects
In 2024, South 8 Technologies secured a strategic investment from Porsche Ventures, marking a significant step toward implementing their technology in high-performance electric vehicles. The company received recognition in TIME’s Best Inventions 2024 for their LiGas technology in the Green Energy category. Additionally, in January 2025, the U.S. Army awarded South 8 a $1.6 million contract to develop specialized battery packs for military applications in extreme conditions, focusing on Arctic LiGas cells for devices such as radios and night vision equipment.
