Déi “new” era of new energy is being ignited by a single “sodium” Batterie.
On April 21, at a “Super Tech Day” described internally as having the “highest technical density since the company’s inception,” Wu Kai—Chief Scientist of CATL and Academician of the Chinese Academy of Engineering—announced that sodium-ion batteries hold vast prospects for energy storage and mobility in extreme conditions, such as high heat and severe cold. He confirmed that CATL has resolved core manufacturing challenges, and mass production is set to begin within this year. This news has struck the trillion-dollar new energy market like a bombshell, marking the official transition of sodium battery technology from a “backup option” to a “mainstream strategic choice.”
In recent years, the dramatic volatility of lithium carbonate prices has created widespread industry anxiety regarding supply chain security. Sodium, with its cost advantages and unique low-temperature performance, has become the industry’s great hope. Elo, as top-tier players like CATL and BYD enter the fray with full supply chain integration, technical bottlenecks are being cleared, commercialization is accelerating, and a new energy landscape of “Lithium-Sodium Coexistence” has begun.
“The current fluctuation in lithium prices highlights the cost benefits of sodium. Coupled with a surge in demand from new scenarios like Artificial Intelligence Data Centers (AIDC), 2026 will be the pivotal year for the large-scale commercialization of sodium-ion batteries,” predicted Xu Zhongling, Dean of the Central Research Institute of Sunwoda Mobility Energy IT Co., Ltd., in a recent interview.
Mass Production Announced for Q4 2026
At the April 21 Super Tech Day, CATL’s CTO, Gao Huan, announced that the highly anticipated sodium-ion batteries will reach scale production in the fourth quarter of 2026. He noted that the company has overcome four major industrial hurdles: extreme moisture control, hard carbon gas evolution, aluminum foil bonding bottlenecks, and the scale production of self-generating anodes. These breakthroughs have injected powerful momentum into the industrialization of sodium batteries.
This strategic shift is backed by massive investment. Data shows that by 2025, CATL had invested nearly 10 billion RMB in sodium battery R&D. Chairman Robin Zeng holds high expectations, predicting that sodium-ion batteries could eventually replace 30% zu 40% of the existing battery market share, reshaping the industry rather than merely supplementing it.
Commercialization is already quietly underway. CATL previously announced large-scale applications across battery swapping, passenger vehicles, commercial vehicles, and energy storage. In early 2026, the company launched the first mass-produced sodium battery for light commercial vehicles through its “Tianshing II” solution. Ausserdeem, the world’s first mass-produced sodium-powered passenger car—a collaboration between Changan Automobile and CATL—is expected to hit the market by mid-2026.
A Competitive Field: Battery Giants Join the Race
CATL is not alone on this track. BYD has long established a deep layout in sodium technology. He Long, Senior VP of BYD and CEO of FinDreams Battery, stated that “sodium-ion batteries are an extension of BYD’s LFP (Lithium Eisen Bosphat) strategy.” BYD’s third-generation platform has already solved technical issues regarding high-temperature performance and sodium plating, achieving a breakthrough of over 10,000 Zyklen.
Other manufacturers are also moving fast:
-
Sunwoda: Has finalized its sodium-ion platform products and is ready for mass production, with projects in the energy storage sector moving forward.
-
EVE Energie: Successfully commissioned its first large-capacity sodium-ion storage system in September 2025.
-
Gotion High-Tech: Reported to be launching new sodium products in mid-May 2026.
This collective push has resonated throughout the supply chain. Upstream material providers like Tianqi Lithium and specialized firms like CNGR Advanced Material are reporting rapid progress in R&D and order fulfillment.
Cost Advantages and Technical Milestones
The primary driver for sodium technology is the high and unstable price of lithium. Experts point out that battery-grade lithium carbonate prices surged by over 100% in early 2026 compared to late 2025, repeatedly crossing industry break-even lines. In contrast, sodium is abundant, globally distributed, and low-cost, providing a natural safeguard for supply chain security.
The cost advantage is now materializing. In Q1 2026, sodium cell costs dropped to 0.35–0.40 RMB/Wh, narrowing the price gap with LFP to within 0.1 RMB/Wh. CATL revealed that its sodium cells are already 30% zu 40% cheaper than LFP, with a potential for another 20% zu 30% reduction as capacity scales.
Technically, CATL has increased energy density by 50% through innovations in ion-desolvation and anti-freeze electrolytes. Most notably, sodium batteries perform exceptionally in the cold: at -30°C, discharge power is nearly triple that of conventional LFP models; at -40°C, capacity retention exceeds 90%; and they remain stable even at -50°C.
Complementary Roles: The Future of Sodium and Lithium
Despite the progress, experts remind us that energy density remains sodium’s “Achilles’ heel.” Currently, it is mostly capped at around 160 Wh/kg, which limits its independent use in high-end vehicles. Most sodium-powered cars are currently priced below 100,000 RMB (A0-class micro-EVs).
Allerdéngs, the industry consensus is that sodium and lithium are not in a “zero-sum” competition. Amplaz, they will coexist. Lithium will continue to power high-performance, long-range vehicles, while sodium will carve out its own path in energy storage, two-wheelers, commercial vehicles, and budget-friendly EVs.
By 2035, sodium batteries are projected to capture approximately 10% of the global battery market, with demand exceeding 365 GWh. From a laboratory curiosity to a widely accepted industrial standard, 2026 marks the “highlight moment” for sodium batteries, driven by the powerful combination of cost, Technologie, and market demand.
