Supply agreements for sodium-ion batteries now total more than 70 GWh worldwide, according to Wood Mackenzie. The analysis finds the chemistry is approaching cell-level cost parity with LFP batteries, though module and system-level parity is not expected until after 2030.
Why it matters
Sodium-ion batteries offer supply chain diversification and strong low-temperature performance, positioning them as an alternative to lithium-based chemistries. The findings suggest the chemistry's economic case depends on total cost of ownership rather than upfront price alone.
The analysis reports sodium-ion upfront costs of $229/kWh globally against roughly $200/kWh for LFP, with a projected 21% lower total cost of ownership over 20 years. Planned manufacturing capacity currently exceeds demand, and the 2030-2035 period is expected to be decisive for economic competitiveness.
The players
Wood Mackenzie
A global research and consulting firm whose analysis of sodium-ion supply agreements and total cost of ownership is the basis of this report.
CATL
China's Contemporary Amperex Technology Co. Limited, one of the world's largest battery makers, which is targeting 1 GWh of sodium-ion shipments by the end of 2026.
BYD
Build Your Dreams, a Chinese manufacturer with planned sodium-ion manufacturing capacity of 30 GWh.
The details
The study analyzed markets in China, the United States, Germany, and India, estimating total cost of ownership over a 20-year project lifetime. The advantage is attributed to eliminating capacity expansion cycles and lowering operating costs.
Timeline
July 2026: China reintroduced a consumption tax on lithium-ion batteries, exempting sodium-ion batteries.
September 2026: A 2% levy began applying to LFP batteries.
Late 2026: Leading manufacturers are expected to reach cell-level cost parity with LFP.
September 2027: The LFP levy is set to rise to 4%.
End of 2028: The sodium-ion consumption tax exemption expires.
Deeper Dive
The trajectory mirrors the commercialization path LFP itself followed, now approaching cost parity with the incumbent chemistry that dominates grid storage. Whether sodium-ion follows that path depends on the 2030-2035 window the analysis identifies as decisive.
If sodium-ion reaches cell-level parity as projected, it could offer a lower-cost storage option with better cold-weather performance and reduced reliance on lithium supply chains. Consumers and grid operators would see the effect through storage pricing rather than immediate product changes.
The takeaway
Total cost of ownership, not upfront price, is the measure that will determine whether sodium-ion batteries compete with LFP over the coming decade. Storage buyers evaluating chemistries should weigh lifetime operating costs alongside purchase price.
What happens next
China's LFP levy is scheduled to rise to 4% in September 2027, and the sodium-ion consumption tax exemption expires at the end of 2028.
