China's Five-Year Plan Positions Sodium-ion Batteries as 'Low-Cost, Long-Life'
China's 15th Five-Year Plan positions sodium-ion batteries as a 'low-cost, long-life' solution, primarily competing with LFP. Tax exemptions support growth, but challenges like hard carbon costs and the absence of residual value post-2028 demand continuous attention.
The Chinese government recently unveiled its vision for the development of the electronic information manufacturing industry within the 15th Five-Year Plan. While much attention was drawn to general growth figures, the plan offers specific insights for the sodium-ion battery sector. The emphasis here is on the 'low-cost, long-life' attributes of these batteries, a positioning that SMM believes reflects market realities.
In contrast to lithium batteries, characterized by 'high safety,' or solid-state batteries with 'high specific energy,' the plan for sodium-ion technology highlights economic advantages. This is because the energy density ceiling of sodium-ion is lower than that of LFP (lithium iron phosphate), and its inherent thermal stability, though superior to liquid lithium batteries, is not currently its most distinctive selling point. Consequently, the primary competitive position for sodium-ion batteries is their cost per kWh, in direct comparison with LFP.
A significant incentive is the exemption from consumption tax for sodium-ion batteries until the end of 2028. This measure, which directly impacts costs, is viewed as an 'economic insurance policy' aiding the sector during its ramp-up phase. Concurrently, lithium carbonate prices have recently seen substantial declines, reducing costs for LFP battery cells. The cost savings from the tax exemption for sodium-ion and the lithium price drop for LFP are of a similar magnitude, intensifying the competitive landscape. Therefore, the economic viability of sodium-ion is not a given but requires continuous cost reduction.
The availability and cost of hard carbon anodes represent a crucial constraint for sodium-ion batteries. One GWh of sodium-ion batteries requires approximately 1,500 metric tons of hard carbon anode, while the global annual supply of coconut shell-based hard carbon is limited to less than 80,000 metric tons. The cost trajectory of hard carbon will be decisive for sodium-ion batteries' ability to further reduce their overall costs.
Technologically, the polyanion route dominates production, accounting for nearly 90% in August 2026. This preference is logical, as polyanion cathodes offer superior cycle life, wide operating temperature range, and thermal stability, making them highly suitable for energy storage applications. This aligns with the 'low-cost, long-life' focus suggested by the plan.
Finally, SMM emphasizes the necessity of considering full life-cycle costs. While sodium-ion batteries contain no lithium, cobalt, or nickel and thus lack recycling value, this also implies an absence of residual value. End-of-life processing costs, often overlooked today, will become a significant factor after 2028. The true test for sodium-ion batteries, therefore, lies beyond the period of policy protection.
