NASA tests solid-state battery prototypes for extreme lunar conditions
NASA’s SPEARS project is developing solid-state batteries for future operations in harsh lunar environments.
What the record says
NASA’s October 14 report describes prototype-cell thermal-vacuum testing at Langley Research Center. SPEARS replaces liquid electrolytes with solid materials and is studying performance and survival across temperature extremes. NASA Glenn leads the project, with other agency centers supporting development.

Practical next step
Consult NASA’s project report for the tested conditions and development plans.
Limits and what is not established
Prototype results do not establish a flight-qualified product or operation at every lunar temperature. NASA distinguishes surviving extreme cold from operating while that cold; warming may still be required.
