At this point, the sodium-ion battery track has formed a competitive landscape in which traditional lithium battery manufacturers are aggressively entering the field while new sodium-ion battery players defend their positions and seek breakthroughs. The two camps each have distinct strengths and weaknesses and are jointly shaping the industry’s direction.
I. New Sodium-Ion Battery Enterprises: Building Strong Barriers Through Technology and First-Mover Advantages
As pioneers on this track, new sodium-ion battery enterprises have developed unique competitiveness in technology, mass production, and client engagement, with their core advantages concentrated in four aspects.
First, they have deep technical R&D accumulation and leading product performance. These new players started early and remained focused on the sodium-ion battery field. Their core teams mostly have academic and scientific research backgrounds, and with the support of research institutions, they have accumulated ample experience in key areas such as NFPP cathodes, electrolyte, and hard carbon anodes. Compared with traditional lithium battery manufacturers, their products offer stronger performance advantages, making them well suited for scenarios such as energy storage and passenger vehicles in extremely cold regions. Their flexible operating mechanisms also enable them to respond quickly to the needs of technology iteration.Second, they started mass production earlier and have extensive experience in scaling up. While traditional lithium battery manufacturers were still at the production line planning stage, these new players had already achieved the breakthrough from R&D to mass production. Some enterprises have built 10-kt-level NFPP production lines and possess stable mass production capabilities as well as mature management and control experience. Their capacity utilization rate has risen steadily, forming a clear advantage in mass production.
Third, they have built deep client relationships and maintain a stable order base. In the early stage, these new players focused on downstream sodium-ion battery cell clients and established long-term cooperative relationships, securing stable orders. They have strong client stickiness in scenarios such as energy storage and two-wheeled electric vehicles, and have also begun to establish a sodium-ion battery brand effect, further consolidating the foundation for cooperation. Fourth, the strategic focus is clear, and resistance to transformation is low. Unlike the model adopted by traditional lithium battery manufacturers, where “lithium batteries are primary and sodium-ion batteries are supplementary,” new entrants are focused on the single track of sodium-ion batteries. Unencumbered by legacy businesses, they can concentrate resources, make flexible decisions, and align with the pace of industry development.
Despite their significant advantages, new entrants still have clear shortcomings. On the one hand, their financial strength is weak, limiting their capacity expansion capabilities. Most new entrants are small and medium-sized enterprises with limited financing channels, making it difficult for them to shoulder the huge investment required for capacity expansion and R&D. Their expansion pace cannot keep up with market demand, and they also struggle to integrate the upstream supply chain to reduce costs. On the other hand, their client structure is relatively single, and their market coverage is limited. Their partners are mainly small and medium-sized sodium-ion battery cell enterprises, with relatively little cooperation with top-tier battery cell enterprises, and their market presence is concentrated in low and mid-end application scenarios,
leaving them with insufficient risk resistance. In addition, their industry chain integration capability is inadequate, making them vulnerable to fluctuations in raw material supply and demand, while the degree of product standardization still needs improvement.
II. Traditional Lithium Battery Manufacturers: Leveraging Established Foundations to Accelerate Breakthroughs with Capital and Supply Chain Advantages
Traditional lithium battery manufacturers, especially lithium battery cathode enterprises, have rapidly expanded into sodium-ion batteries by leveraging the advantages they have accumulated in the lithium battery sector, including capital, supply chain, and client resources. Their core strengths are concentrated in resource integration and economies of scale potential.
First, they are financially strong and well-positioned for capacity expansion. Traditional lithium battery manufacturers have stable profitability and ample capital, allowing them to easily bear the investment required for sodium-ion battery production line upgrades, capacity expansion, and R&D. They can rapidly advance capacity expansion plans and reduce costs through scaled procurement, and some top-tier enterprises have already planned large sodium-ion battery shipment targets.
Second, they have deep supply chain and client resources, creating significant synergies. Traditional lithium battery manufacturers have established long-term and stable partnerships with downstream battery cell, vehicle, and energy storage enterprises.
After entering the sodium-ion battery market, they can quickly leverage existing resources to promote products and lower market development costs. Their supply chain integration capability in the lithium battery field can also be transferred to sodium-ion batteries, ensuring a stable supply of raw materials and, over time, enabling them to build price advantages through economies of scale.
Third, they have extensive production management experience and high efficiency in bringing capacity online. Traditional lithium battery manufacturers possess mature production and quality control experience that can be transferred to sodium-ion battery production lines, improving yield rates and shortening the capacity ramp-up cycle. Some production equipment is also compatible with sodium-ion battery production lines, eliminating the need for huge investment in new equipment and improving the efficiency of bringing capacity online.
Finally, the advantages of policy support and resource prioritization were evident. Traditional lithium battery manufacturers were mostly industry leaders and maintained close cooperation with governments and industry associations, enabling them to enjoy policy support and resource prioritization on a priority basis, while also participating in the formulation of industry standards to consolidate their market positions.
The shortcomings of traditional lithium battery manufacturers were concentrated at the technical and strategic levels. First, R&D lagged behind, and the gap in product performance was obvious. Their R&D center had long been on lithium batteries; sodium-ion battery R&D started late and lacked sufficient technical reserves, leaving product performance behind that of emerging players. In addition, their R&D mechanisms were rigid and decision-making efficiency was low, making it difficult to respond to the needs of technological iteration. Second, their strategic center had shifted, and resource allocation was insufficient. Lithium batteries remained the core business, while sodium-ion batteries had not yet formed a clear profit growth driver, so enterprises allocated limited resources to sodium-ion batteries, constraining their long-term development. Third, the burden of transformation was relatively heavy, and decision-making flexibility was insufficient. These enterprises were large in scale and complex in organization, with high sunk costs in their lithium battery businesses. As a result, transformation faced strong resistance, deployment pace was conservative, and the retrofitting of some production lines was time- and labor-intensive, constraining the realization of capacity.
III. Core Competition on the Track: Two-Way Complementarity and Competition Under the Dominance of Supply Chain Security
Competition in the sodium-ion battery track in 2026 was essentially a contest between technological and first-mover advantages on one side and capital and supply chain advantages on the other, while the supplier selection logic of downstream battery cell manufacturers intensified the competition.
The core criterion for battery cell manufacturers in selecting suppliers was supply chain security. Considerations such as capacity, performance, cost, capacity responsiveness, and product compatibility determined that the competitive focus of the two camps was concentrated on capacity realization, performance optimization, and cost control.
The two camps were not in absolute opposition; rather, competition and complementarity coexisted. The technological advantages of emerging players could make up for the R&D shortcomings of traditional lithium battery manufacturers, while the capital and supply chain advantages of traditional lithium battery manufacturers could provide useful reference for emerging players. As the industry matured, a differentiated landscape was expected to take shape: emerging players would focus on technological iteration and breakthroughs in niche scenarios to consolidate their advantages in the high-end segment,
while traditional lithium battery manufacturers would rely on scale to drive down costs and accelerate the popularization of sodium-ion batteries.
As the inaugural year of large-scale sodium-ion battery application, 2026 still saw the industry facing challenges such as costs, raw material supply, and the improvement of standards. For both camps, leveraging strengths, addressing weaknesses, and seizing development opportunities would be key to determining their future position on the track. In the future, sodium-ion batteries and lithium batteries would develop in coordination, jointly supporting the diversification of the new energy industry and advancing the energy transition.
