South 8 Technologies Secures $9.2M Grant in California to Expand LiGas Electrolyte Production in San Diego

Key Takeaways

South 8 Technologies secured a $9.2 million grant from California’s PowerForward Battery Manufacturing program to expand its LiGas® electrolyte production.
The innovative LiGas technology operates effectively in extreme temperatures, enhancing performance for cold climates and aerospace applications.
The company aims to achieve significant production milestones by 2028, integrating with partners to improve battery manufacturing capabilities.

Expansion of Innovative Battery Technology

South 8 Technologies, a San Diego-based battery startup, has announced a $9.2 million grant agreement under California’s PowerForward Battery Manufacturing program. This initiative is part of a broader $67 million California Energy Commission program, designed to foster zero-emission vehicle battery manufacturing within the state. The grant will support the expansion of South 8’s production capabilities for its LiGas® liquefied gas electrolyte.

LiGas technology replaces traditional liquid electrolytes with a specially developed blend of non-toxic gases held under pressure. This approach significantly enhances performance across a wider temperature range, functioning effectively from –60 °C to +60 °C, while conventional electrolytes exhibit weaknesses at 0 °C and freeze at –20 °C. South 8 has set ambitious goals, targeting a specific energy output exceeding 425 Wh/kg, making the technology particularly relevant for electric vehicles operating in cold climates and for defense and aerospace sectors where traditional battery cells typically fail.

The grant will allow South 8 to establish an annual production capacity of 100 MWh of LiGas electrolyte and 2 MWh of battery cells at its headquarters in San Diego. The cell manufacturing process will involve collaboration with Nanotech Energy, a strategic partner. South 8 is working towards being fully integrated with gigafactory standards for LiGas by 2028.

Jungwoo Lee, CEO of South 8 Technologies, expressed enthusiasm about scaling production, stating, “We’re excited to scale production of our advanced LiGas electrolyte and high-performance, resilient battery cells.” The company has garnered interest from various investors, particularly those with a focus on defense and extreme-environment scenarios, including Lockheed Martin Ventures, W. L. Gore & Associates, and Porsche Ventures. Additionally, South 8 has partnered with LG Energy Solution to explore aerospace battery applications.

This strategic expansion not only aligns with California’s mission to promote sustainable battery production but also positions South 8 as a key player in the evolving battery technology landscape. With a focus on resilience and performance, the company is poised to meet the growing demands of electric vehicle manufacturers and other high-performance sectors.
