Why 2026 Could Be the Breakout Year for Sodium-Ion Batteries
Key Takeaways
- Sodium-ion battery costs have dropped to $40-60 per kilowatt-hour, nearing lithium iron phosphate parity
- CATL, BYD, and several startups are scaling sodium-ion production for EVs and grid storage
- Sodium is globally abundant, eliminating the supply chain risks associated with lithium
- Grid-scale energy storage is the likely first market for massive sodium-ion adoption
- Energy density remains lower than lithium-ion but is sufficient for many applications
