Sodium-Ion Battery Low-Temperature Performance
Sodium-Ion Battery Low-Temperature Performance
Sodium ion low temperature behavior is a key advantage: sodium cells retain more capacity at -20C than LFP, making them attractive for cold regions.
Cold Retention (typical)
| Temp | Sodium | LFP |
|---|---|---|
| 0C | ~95% | ~90% |
| -20C | ~80% | ~60-70% |
Where It Helps
- Northern home storage and telecom.
- Winter two-wheeler and e-mobility.
- Cold-chain and outdoor equipment.

Frequently Asked Questions
Why is sodium better in cold?
Its electrochemistry tolerates low temperatures with less capacity loss than LFP.
Any cold charging limit?
As with all Li-based cells, limit charge current at very low temps; sodium is more forgiving.
