Sodium-Ion Battery Cathode Materials: The Options
Sodium-Ion Battery Cathode Materials
Sodium ion battery cathode materials mainly split into layered oxides (higher energy) and polyanions (longer life, lower cost).

Options
| Type | Edge |
|---|---|
| Layered oxide | Energy density |
| Polyanion | Life, cost |
| Prussian blue | Low cost |
Selection
- Energy-critical uses: layered oxide.
- Cost/life-critical: polyanion.
See the chemistry overview in our sodium ion battery guide.
Frequently Asked Questions
Which is cheapest?
Prussian blue and polyanion families lean lower cost; layered oxides trade up for energy.
Does cathode choice affect safety?
Yes – some polyanions are especially stable; match to application.
