The collaboration aligns with a broader aerospace initiative involving KULR Technology Group and NASA to create cold-temperature battery systems for lunar and Martian exploration missions, supported by a $6.7 million grant from the Texas Space Commission. Under the agreement, LG Energy Solution will focus on design, testing, and evaluation of lithium-ion cells, while South 8 Technologies will manufacture enhanced cells using its patented liquefied gas electrolyte (LiGas®) capable of operating at -60°C. These advanced cells will be integrated into KULR’s One Space battery platform, ensuring optimal performance for space missions. The partnership builds on years of collaboration since LG Energy Solution’s Startup Challenge Program in 2019, further strengthening its position in the emerging aerospace energy sector.
