Sodium-ion batteries near LFP cell cost parity, Wood Mackenzie says
Original title: Sodium-ion batteries approach cost parity with LFP
Analysts cite more than 70 GWh of supply agreements and a possible 21% lower 20-year ownership cost than LFP.
Wood Mackenzie says sodium-ion cells are entering commercial production and could match lithium iron phosphate cell cost by late 2026, with module and system parity only after 2030. Average cell cost is $229/kWh versus about $200/kWh for LFP, but the firm estimates 21% lower total cost of ownership over 20 years. China leads: BYD plans 30 GWh of capacity and CATL aims to ship more than 1 GWh by the end of 2026. China, the United States, Europe and India are using tax, tariff or incentive policy that could shift chemistry choice.
Unconfirmed: Cost parity, ownership savings and shipment figures are Wood Mackenzie estimates, not measured market results.
- Supply agreements already exceed 70 GWh in China, the United States and Europe.
- China's estimated learning rate for 2026–2035 is 18% to 20%.
- China exempted sodium-ion from a consumption tax through the end of 2028.
- LFP faces a 2% Chinese levy from September 2026, rising to 4% in September 2027.
- US tariffs of about 58% on Chinese storage cells plus Section 45X credits favor domestic plants.
