Sodium-Ion Battery Manufacturing Process
Sodium-Ion Battery Manufacturing Process
The sodium ion battery manufacturing process largely reuses Li-ion coating and assembly lines, which is why sodium can scale faster and cheaper than solid-state.
Process Steps
- Slurry mixing of cathode/anode.
- Coating and calendering.
- Cell assembly (cylindrical/prismatic/pouch).
- Formation and grading.
Why Lower Capex
| Factor | Effect |
|---|---|
| Line reuse | Lower CAPEX |
| No cobalt/nickel | Cheaper material |
| Aluminium anode foil | Cheaper than copper |

Frequently Asked Questions
Can Li-ion factories switch?
Largely yes – the equipment is similar; some material handling changes.
Is yield mature?
Improving fast as volume grows; still below Li-ion in places.
