## Summary
NASA has developed batteries utilizing solid ceramic or polymer electrolytes to overcome the temperature limitations of liquid electrolytes. These batteries can operate meaningfully from -60°C to 80°C and showed no damage or capacity loss after being exposed to -170°C. The technology is intended for lunar exploration in permanently shadowed craters and other extreme environments.

## Solid-state electrolyte advantages
- Uses **ceramic or polymer** solid electrolytes instead of liquid ones.
- Operational temperature range: **-60°C to 80°C**.
- Survival testing: No damage observed at **-170°C**.
- Post-extreme cold testing showed **no capacity loss** after heating back to operating range.
- Reduces the need for complex thermal management systems.

## Why it matters
These batteries could enable long-term scientific missions in lunar environments and reduce thermal management requirements for terrestrial applications.
