1. Sodium-Ion Battery Technology Overview
Sodium-ion batteries operate on the same fundamental principle as lithium-ion batteries—ions shuttle between a cathode and an anode during charge and discharge—but use sodium ions (Na+) instead of lithium ions (Li+). The key technological differences lie in the materials used for each component, which collectively deliver a different cost-performance profile optimized for stationary and low-mobility applications.
1.1 Component Architecture
| Component | Sodium-Ion | Lithium-Ion (LFP) | Cost Advantage |
|---|---|---|---|
| Cathode | Layered sodium transition metal oxide (NaₓMO₂) / Prussian blue analogue | Lithium iron phosphate (LiFePO₄) | 30-40% cheaper (no Li, no Co) |
| Anode | Hard carbon (from biomass or petroleum pitch) | Graphite | 20-30% cheaper |
| Electrolyte | NaPF₆ in carbonate solvents | LiPF₆ in carbonate solvents | 15-25% cheaper |
| Separator | Polyethylene/polypropylene (same as Li-ion) | Polyethylene/polypropylene | Same cost |
| Current collector (anode) | Aluminum (both sides) | Copper (anode side) | 40-50% cheaper (Al vs Cu) |
| Cell format | Cylindrical 26700 / prismatic | Cylindrical / prismatic / pouch | Same manufacturing equipment |
A critical advantage: sodium-ion batteries use aluminum current collectors on both electrodes, whereas lithium-ion requires copper on the anode side. Since aluminum costs roughly one-third of copper, this alone reduces material costs significantly. Additionally, existing lithium-ion production lines can be retrofitted for sodium-ion manufacturing with minimal capital investment.
