GoKawiilNASA details solid-state battery project aimed at surviving Moon and Mars temperatures
NASA has published details of its SPEARS project, which is developing batteries using solid ceramic or polymer materials instead of liquid electrolytes found in standard lithium-ion cells. The goal is to create batteries that can endure the Moon's extreme temperature swings, from 212°F daytime highs to minus 328°F lows at the lunar south pole, for use in future Artemis missions and Mars exploration.
GoKawiil's interpretation of the reporting above, not reported fact.
Current lithium-ion batteries degrade or fail in extreme heat and cold, which has limited equipment design for lunar and Martian missions requiring heavy thermal management systems. NASA's solid-state approach, which reportedly needs less energy-intensive heating and resists cold damage, could simplify mission hardware and extend operational windows in harsh environments. The technology's potential crossover to Earth-based electronics suggests broader commercial interest beyond space applications, though NASA has not detailed a timeline for terrestrial use.
- NASA's SPEARS project is developing solid-state batteries using ceramic or polymer materials instead of liquid electrolytes.
- The batteries are designed to survive lunar temperature extremes ranging from 212°F to minus 328°F.
- The technology is also being explored for Mars missions and could eventually find use in Earth-based electronics.
