South 8 Technologies has raised $11 million in a follow-on funding round co-led by W. L. Gore & Associates' venture arm and Lockheed Martin Ventures. Participants included Anzu Partners, IQT, LG Technology Ventures, Porsche Ventures, Foothill Ventures, Alumni Ventures and Galvion. The San Diego-based company develops LiGas, a liquefied gas electrolyte for lithium-ion batteries that operates from minus 60°C to plus 60°C. The technology enables charging in freezing conditions and includes a thermal fuse to reduce fire risk during battery abuse. The funding will expand manufacturing capacity to produce cylindrical cells for defence and aerospace applications, including soldier power systems, unmanned aerial systems and space platforms. South 8 has secured over $32 million in non-dilutive funding and has strategic partnerships with LG Energy Solution, Galvion and CTNS.

LG Energy Solution * LG Energy Solution signs strategic development collaboration with a visionary U.S. startup South 8 Technologies to co-develop space-rated batteries capable of functioning at ultra-low temperatures as low as -60 °C * Companies to join forces with KULR Technology Group and NASA to secure extreme-environment battery technologies for next-generation space missions SEOUL, South Korea, Nov. 12, 2025 /PRNewswire/ - LG Energy Solution today announced a strategic partnership with South 8 Technologies to jointly develop space-rated lithium-ion batteries optimized for extreme low temperatures. This agreement positions LG Energy Solution to participate in the development of next-generation battery technologies that can withstand harshest environments, establishing a foothold in the emerging aerospace sector. "The liquefied gas electrolyte technology fundamentally addresses the long-standing issues of battery performance degradation in extreme cold environments," said Je Young Kim, CTO of LG Energy Solution. "We anticipate that this technology will unlock unprecedented possibilities to pioneer new products and applications including the space." The two companies' cooperation is part of a larger aerospace initiative involving KULR Technology Group, Inc (NYSE American: KULR) and NASA to develop cold-temperature battery solutions for the next generation of deep space missions. KULR, a leading provider of cutting-edge energy storage solutions for aerospace and defense, recently secured a funding of $6.7 million from the Texas Space Commission to develop cold-temperature lithium-ion battery solutions for lunar and Martian exploration missions. The program is being carried out in close collaboration with NASA Johnson Space Center (JSC). LG Energy Solution is determined to play a key role in this joint effort, helping propel the development of next-generation aerospace battery technologies. Specifically, the company will support in the design, testing, and evaluation of lithium-ion battery cells. South 8 Technologies will then manufacture enhanced battery cells using its proprietary and innovative liquefied gas electrolyte and electrolyte filling technology. These cells, operating at temperatures as low as -60 °C, will be integrated into KULR's One Space battery architecture platform, providing optimal performance for extreme environments encountered during space missions. South 8 Technologies is a U.S. startup company that has developed the world's first liquefied gas (LiGas(R) electrolyte, a patented solution that enhances battery performance by enabling ultra-low temperature operation down to -60 °C, significantly outperforming conventional liquid electrolytes that struggle below -20°C. This technology was recognized as one of TIME magazine's 'Best Inventions of 2024.' Moreover, the liquefied gas electrolyte has the potential to drastically enhance battery safety under physical or electrical abuse conditions. When such shocks occur, the liquid solvent inside the battery will rapidly evaporate, reducing the cell temperature and expelling the evaporated electrolyte. This process effectively renders the cell a non-functional "dummy cell", significantly reducing risks such as thermal incidents. LG Energy Solution first connected with South 8 Technologies through its Startup Challenge Program in 2019 and has maintained active collaboration since. In 2024, the companies signed a joint development agreement and began the development of the liquefied gas electrolyte-based batteries. The latest agreement announced today further cements the cooperative relationship between the two companies.
