Sodium-ion batteries are nearing cost parity with LFP technology, with over 70 GWh of supply agreements already in place globally. According to Wood Mackenzie, these batteries could offer a 21% lower total cost of ownership over 20 years despite higher upfront costs. China is leading commercialization, with BYD targeting 30 GWh of manufacturing capacity and CATL aiming for over 1 GWh in shipments by late 2026.
The technology is emerging as a viable alternative to lithium-ion for stationary energy storage, driven by supply chain diversification, strong low-temperature performance, and favorable policies. In China, sodium-ion batteries are exempt from a new consumption tax until 2028, while U.S. tariffs and IRA incentives encourage domestic production. Europe’s Battery Regulation may favor sodium-ion due to lower reliance on critical raw materials.
India is supporting development with a $1.25 billion incentive program. Wood Mackenzie expects the 2030–2035 period to be decisive for economic competitiveness.
