Sodium-ion Battery Tax Exemption Policy Takes Effect, Accelerating Industrialization

From September 1, 2024, through the end of 2028, China will exempt sodium-ion batteries from consumption tax while implementing a phased consumption tax on lithium-ion batteries. This policy aims to optimize the battery industry structure and support the nascent sodium-ion battery sector. Over this 28-month policy window, a tax differential of 2% to 4% between sodium-ion and lithium-ion batteries will emerge, providing significant impetus for the large-scale adoption and commercialization of sodium-ion batteries. Following the policy clarification, downstream market sentiment has shifted markedly. Previously, most integrators and automakers adopted a cautious stance toward sodium-ion batteries, conducting only small-batch trials with slow project implementation. Since the policy announcement, however, customer inquiries and willingness to collaborate have risen substantially, accelerating the industry into a phase of scaled deployment. Some sodium-ion battery manufacturers report that clients in automotive and energy storage sectors are reassessing their technology selection criteria, placing greater emphasis on total cost of ownership over the product lifecycle. This shift in demand is propagating upstream along the supply chain. Anode material suppliers note that previously hesitant customers have begun initiating evaluations or pilot trials. Cell manufacturers observe heightened interest in applications such as start-stop power systems and energy storage, with clients increasingly valuing sodium-ion batteries’ advantages in high-rate performance. Leading companies are now accelerating capacity expansion. One sodium-ion battery maker’s production base in Meishan is operating at full capacity and plans to further increase output by year-end, alongside launching a sub-brand focused on light-duty power applications to advance commercialization. Another materials company is expediting the expansion of its production line in Zigong, aiming to reduce costs through economies of scale. Although renewed demand expectations have spurred mid- and upstream players to accelerate production line construction, the industry overall remains rational. Industry insiders stress that the consumption tax exemption comes with technical and delivery thresholds—companies relying solely on policy benefits will struggle to sustain long-term competitiveness, and those lacking stable technological capabilities and reliable delivery capacity risk being phased out.
