Aug 03, 2026

• Introduction: Lithium supply volatility vs. sodium abundance—why Na-ion is dominating stationary storage.
• Core Chemistry Explained:
- Cathode Chemistries: Prussian Blue Analogues (PBA) vs. Layered Transition Metal Oxides.
- Anode Materials: Why graphite fails for Na-ion and how Hard Carbon solves the problem.
- Electrolyte Formulations: Sodium salts (NaPF6) in carbonate solvents.
• Performance Metrics: Energy density (120–160 Wh/kg) vs. cycle life, safety, and sub-zero performance.
• Commercialization Status: Industrial applications in grid storage and two-wheeler EVs.
