Sodium-ion vs LiFePO4 vs lead-acid
No battery chemistry wins every category. Sodium-ion should be assessed against the actual job: cost, temperature, weight, safety profile, cycle life, charge compatibility, and warranty support.
| Question | What to compare |
|---|---|
| Is it for mobile use? | Weight, vibration resistance, charge system, support. |
| Is it for stationary storage? | Cycle life, installed cost, enclosure, inverter compatibility. |
| Is it replacing lead-acid? | Charge profile, usable capacity, BMS behaviour, warranty. |
| Is sodium available now? | Supplier stock, documentation, certification, local support. |
Future articles will compare actual products rather than chemistry labels alone.
