In June, the sodium-ion battery industry chain saw broad-based improvements. The electrolyte and cell segments, which posted the most notable increases during this cycle, exhibited typical features of “volume growth amid persistent bottlenecks”—electrolyte capacity relied on conversion from lithium battery production, and core raw material shortages began to emerge, while the cell segment recorded nearly twofold YoY growth driven by dual boosts from energy storage and two-wheelers.

In June, the sodium-ion battery industry chain saw broad-based improvements. The cathode and anode segments continued to face undersupply, with clear seller’s market characteristics. The electrolyte and cell segments, which posted the most notable increases during this cycle, exhibited typical features of “volume growth amid persistent bottlenecks”—electrolyte capacity relied on conversion from lithium battery production, and core raw material shortages began to emerge, while the cell segment recorded nearly twofold YoY growth driven by dual boosts from energy storage and two-wheelers. The following focuses on electrolyte and cells to review June market dynamics and the H2 outlook.

1. Sodium-Ion Battery Electrolyte: Notable Gains but Capacity Reliance; Raw Material Shortage Bottleneck Emerges

In June, sodium-ion battery electrolyte production surged 20% MoM and 130% YoY, a remarkable growth pace. However, it should be noted that current sodium-ion electrolyte capacity heavily depends on surplus capacity conversion from lithium battery electrolyte production, and actual output still struggles to fully match demand increases from the cell segment.

More critically, effective capacity for key upstream raw materials—NaPF6, NaFSI, NaODFB, etc.—remains scarce. The raw material capacity bottleneck acts as a rigid constraint on supply expansion in the electrolyte segment, making it difficult to achieve a rapid breakthrough in the short term.

From the competitive landscape perspective, the sodium-ion electrolyte market has relatively few players, and very few lithium battery electrolyte enterprises have proactively entered the sodium-ion track. The reason: some companies already deployed in sodium-ion electrolyte have tied their supply to downstream major manufacturers, while competitive pressures in the lithium battery electrolyte segment are already high. As a result, certain second-tier electrolyte enterprises tend to lead the charge into sodium-ion batteries to seize first-mover advantages.

Looking ahead to H2, if demand from downstream top-tier cell enterprises ramps up as expected, it will directly boost sodium-ion electrolyte shipments. In July, sodium-ion battery market demand is expected to continue increasing, which may prompt electrolyte companies to elevate their strategic focus on the sodium-ion battery segment. SMM expects July sodium-ion battery electrolyte production to grow 7% MoM and surge 143% YoY.

II. Battery Cells and End-Users: Building Growth Momentum, Energy Storage Volume Surge Expected

The undersupply in the electrolyte segment has not hindered the pace of volume growth in battery cells — strong downstream demand is becoming the core driver of the upturn across the entire industry chain.

In June, sodium-ion battery cell production rose 35% MoM and 194% YoY, the highest growth rate among the four major segments. The incremental growth was concentrated in the two-wheeler and ESS sectors, where the growth potential of the ESS sector is expected to become more pronounced in H2.

Currently, some battery cell manufacturers have begun preparing for H2 production plans, including building stable upstream supply systems and advancing capacity expansion. It is noteworthy that top-tier lithium battery players are gradually clarifying their H2 plans for sodium-ion batteries — sodium-ion batteries can meet the cost-performance requirements of specific application scenarios and also serve as a strategic approach to addressing lithium carbonate price fluctuations. Driven by these dual rationales, the investment by top-tier players in sodium-ion batteries is expected to increase.

In addition, toll processing of sodium-ion battery cells is quite common, which is currently an effective way to rationally utilize existing battery cell capacity and improve capacity utilization rates, while also alleviating the pressure of supply-demand mismatch to some extent.

Sodium-ion batteries are expected to see a notable volume increase in Q3, with clear volume growth signals driven by the dual engines of ESS and two-wheelers and accelerated planning by top-tier players. SMM expects July sodium-ion battery cell production to rise 23% MoM and 198% YoY.

III. Overview: Supply-Demand Mismatch Deepens, Industry Chain Enters Growth Window Period

In June, the sodium-ion battery industry chain showed high prosperity, with the undersupply pattern for anode and cathode materials persisting, while the electrolyte and battery cell segments exhibited a divergent trend marked by “volume growth amid bottlenecks.”

The electrolyte segment faces the hard constraint of scarce raw material capacity, and the limitations of relying on surplus lithium battery capacity conversion are gradually emerging; on the battery cell side, despite robust growth momentum, challenges remain in the stability of the upstream supply system. From the perspective of transmission mechanisms, the trend of large electrolyte manufacturers binding supply and the widespread adoption of toll processing models for battery cells both point to the industry chain transitioning from extensive volume release to refined supply-demand matching.

Looking ahead to H2, with the acceleration of energy storage project tenders, the implementation of large-scale procurement by top-tier lithium battery players, and the potential launch and delivery of sodium-ion battery car models, the sodium-ion battery industry chain is expected to enter a critical window for accelerated demand release. During this stage, enterprises with the capability to realize raw material capacity, stable quality control, and cost transmission advantages will be the first to break through in the reshaping competitive landscape.

[SMM Cobalt Morning Meeting Minutes] New Energy Industry Chain Demand Differentiation, Market Awaits Gradual Recovery in Peak Season

This week, the industry chain exhibited a diverging pattern, with upstream raw material and cobalt salt prices weakening while midstream and downstream material prices remained relatively stable. Trading in refined cobalt, intermediate products, cobalt sulphate, cobalt chloride, Co3O4, and cobalt powder was generally sluggish. Downstream buyers mostly maintained just-in-time procurement, as off-season demand was insufficient, and inventory pressure along with low-priced supply continued to weigh on market prices. Although some miners and smelters, supported by high-cost inventory, still intended to hold prices firm, traders and recycling companies became more active in selling, and the decline in the cost of refined cobalt reverse dissolution further strengthened market expectations of pushing for lower prices. In the short term, related product prices still face downward pressure. Ternary cathode precursor, ternary cathode material, and LCO prices remained stable overall. Leading ternary cathode precursor companies performed well in export orders, and domestic production schedules recovered somewhat, but small and medium-sized enterprises were still affected by the off-season. Demand for ternary cathode materials from the EV sector stayed at a high level; some battery cell enterprises stockpiled in advance, and August orders are expected to be stable with slight growth. Consumer-side demand remained mediocre. Affected by sluggish end-use demand and substitution by ternary cathode materials, LCO production and sales remained low, further narrowing enterprises' profit margins. Subsequent market recovery will still depend on the restocking pace in mid-to-late August and the release of demand during the September-October peak season.

[SMM Cobalt Lithium Morning Meeting Minutes] Raw Material Price Divergence Intensifies, Energy Storage Demand Sustains Industry Prosperity

[SMM Cobalt Lithium Morning Meeting Summary: Raw Material Price Divergence Intensifies; Energy Storage Demand Supports Continued Industry Prosperity] This week, the relevant material markets continued to diverge in performance. Upstream ore prices stopped falling and rebounded, but high-price transactions remained constrained. Some ex-China capacities gradually recovered, and market attention shifted from supply disruptions to the pace of new capacity releases. Salt products were supported by maintenance outages, tightening circulation of spot orders, and low inventories, leading to somewhat active spot transactions. However, downstream players still mainly made just-in-time procurement on price dips, and concentrated stockpiling has yet to emerge. The cobalt industry chain remained under pressure overall, with the price centers of refined cobalt, intermediate products, cobalt salts, and cobalt powder shifting downward. Off-season demand, inventory pressure, and low-priced cargoes continued to weigh on the market. Nickel sulphate inventories declined, and cost support strengthened somewhat. Prices of ternary cathode precursors and ternary cathode materials generally remained stable. The LFP, electrolyte, and sodium-ion battery sectors performed relatively strongly, with demand from energy storage, commercial vehicles, and Q3 stockpiling driving production schedules higher. Inventories of some products continued to decline. The anode and separator markets were generally stable. Different raw material varieties in the recycling sector showed divergent performance. The overall industry chain remained in a phase of concurrent demand improvement and cost pass-through.

[SMM Cobalt Morning Brief] Weakness in the cobalt industry chain persists, Q3 restocking remains to be seen.

SMM Cobalt Morning Briefing: This week, the cobalt industry chain continued to be in the doldrums. Refined cobalt prices were lowered to 360,000 yuan/mt, with off-season demand sluggish; for cobalt intermediate products, the price spread between upstream and downstream diverged noticeably, hindering deal progress. In the cobalt salt and Co3O4 markets, inquiries and order signing were limited, and prices mainly moved sideways. Cobalt powder transaction prices remained at 455,000 yuan/mt, but demand was cautious, and there was still short-term pressure to test the bottom. Orders for ternary cathode precursors and ternary cathode materials were relatively stable; LCO prices were lowered due to falling raw material costs; and the market focused on the pace of restocking in Q3.
