Sodium-ion batteries are getting more and more popular, as they offer several advantages in comparison to the currently predominantly used lithium batteries. Sodium-ion batteries are less costly and safer alternatives to lithium-ion ones, with better performance at a large range of temperatures. Furthermore, sodium is abundant in nature, unlike lithium. One of the disadvantages of sodium-ion batteries is the lower energy density.
| Sodium-ion | Lithium-ion | |
|---|---|---|
| Energy density (watt-hours per kilogram) | 160 | 250 |
| Cyclability (number of cycles) | 4,000 | 2,000 |
| Voltage (volts) | 3.7 | 4 |
| Efficiency | Lower | Higher |
| Safety | High | Medium |
| Need for critical materials | No | Yes |
| Cost | Less costly and less volatile | More expensive and more volatile |
| Size | Bulky | Light |
| Low temperature performance | Good performance | Lower performance |
| Charging and discharging time | Fast | Longer duration |
| Flammability | Non-flammable | Flammable |
| Recyclability | Moderate | Difficult |
