Recently, rising prices of key lithium-ion battery (LIB) raw materials have sparked industry concerns. Meanwhile, SIBs are gaining traction across multiple sectors—including electric vehicles (EVs), commercial vehicles, e-bikes, automotive start-stop systems, and energy storage—with their cost-performance ratio steadily improving, now approaching that of lithium iron phosphate (LFP) batteries.

SIBs are transitioning from small-scale demonstrations to mainstream adoption. The competition between SIBs and LIBs is not merely about energy density or cost; it represents a broader struggle over supply chain resilience, application suitability, and energy security.

Part 1. Renewed industry focus on sodium-ion batteries

Recent price volatility in upstream materials—whether for nickel-cobalt-manganese (NCM) or LFP batteries—has drawn significant industry attention.

The surge in cobalt sulfate prices stems primarily from the Democratic Republic of Congo (DRC), the world’s largest cobalt supplier, halting cobalt exports for four months starting February 22. Reports of regional instability have further exacerbated market reactions.

Additionally, the DRC is considering long-term policies to extract greater value from cobalt mining and processing while preventing a post-ban supply glut that could destabilize prices. The DRC’s Economic Situation Committee has proposed stricter export restrictions, including collaboration with Indonesia—the second-largest cobalt producer—to better regulate global supply and pricing.

Cobalt supply constraints have also driven up nickel prices, increasing production costs for NCM and lithium cobalt oxide (LCO) batteries.

Meanwhile, demand growth and product iteration have led to diverging LFP material prices, with premium products seeing sharper increases. High-density LFP materials, crucial for boosting energy density, have gained market favor. However, complex processes like “secondary sintering” have raised manufacturing costs, pushing up prices for fourth-generation high-density LFP. Industry sources reveal that major battery manufacturers have already secured large orders, with one leading supplier reportedly “operating at full capacity.”

Sodium’s crustal abundance (2.74%) is 420 times that of lithium (0.0065%), and SIBs require no scarce metals like cobalt or nickel, nor copper foil current collectors.

In summary, prolonged cobalt production cuts could trigger price spikes, highlighting SIBs’ advantage in mitigating supply chain risks. While mid-to-low-end LFP batteries remain cost-competitive, rising demand for high-density variants is tightening material supplies. As manufacturers prioritize premium LFP production, cost advantages are narrowing—creating opportunities for SIBs in mid- and entry-level markets.

Part 2. Rapid adoption across multiple applications

Industry observers note that SIBs are achieving commercial breakthroughs in EVs, commercial vehicles, e-bikes, start-stop systems, and energy storage, signaling imminent mass adoption.

Passenger EVs: On March 12, Lynk & Co announced its 900 model will feature CATL’s “Xiao Yao” hybrid sodium-lithium battery, offering 400 km (CLTC) range, 4C ultra-fast charging, and operation at -40°C. Its AB battery system intelligently blends SIBs (for low-temperature performance) and LIBs (for energy density).
Heavy-Duty Hybrids: A hybrid dump truck from Sany Group, equipped with Sibei Power’s 8 kWh SIB, recently completed road tests, demonstrating SIBs’ potential in commercial vehicles.
E-Bikes: Yadea and Huayu Na Battery unveiled the “Ultra-Na” ecosystem, featuring 15-minute fast charging (to 80%), while Oppein launched its first mass-produced SIB-powered e-bike with a 72V20Ah sodium battery from Pangu New Energy.
Energy Storage: Hithium’s ∞Cell N162Ah (polyanion-type cathode with hard carbon anode), optimized for wide-temperature/high-rate storage, offers 2.55MWh containerized systems targeting GWh-scale production by Q4 2025. BYD and others have also introduced SIB storage solutions.

Though LIBs still dominate, SIBs—with superior safety, low-temperature performance, and fast-charging capabilities—are rapidly penetrating extreme-temperature and high-power applications. Their industrialization hinges on further cost reductions and efficiency gains.

Part 3. The perfect storm driving SIB adoption

1. Lithium Supply Chain Vulnerabilities Exposed

The lithium-ion battery industry continues to face unprecedented supply chain challenges in 2025. Recent data from Benchmark Mineral Intelligence shows lithium carbonate prices have increased by 28% year-to-date, while cobalt prices remain volatile following export restrictions from the Democratic Republic of Congo (DRC). These developments have exposed critical vulnerabilities in the lithium-ion supply chain:

Geographic concentration of raw materials (70% of cobalt from DRC, 60% of lithium processing in China)
Geopolitical risks affecting material availability
Environmental concerns surrounding mining practices
Fluctuating costs impacting battery pricing stability

2. The Sodium Advantage: Abundance and Stability

Sodium-ion technology offers compelling solutions to these challenges. With sodium being the sixth most abundant element on Earth (2.74% of Earth’s crust versus lithium’s 0.0065%), SIBs provide:

Inherent supply chain security
Reduced geopolitical risk
More stable long-term pricing
Lower environmental impact in extraction

Recent analysis by Wood Mackenzie suggests that SIB raw material costs could be 30-40% lower than LFP batteries at scale, with potential for further reductions as the supply chain matures.
