US sodium-ion startup Unigrid international battery cell shipments mark a pivotal development for the global battery industry. Unigrid, a leading sodium-ion (Na-ion) battery technology company from the United States, has begun large-scale exports of its proprietary sodium cobalt oxide (NCO) cathode cells worldwide. The company is the first battery manufacturer outside China to achieve commercial-scale international shipments of Na-ion cells. Unigrid also plans to fulfill significant off-take agreements later this year, reinforcing its rapid commercial progress.
Unigrid’s Global Sodium-ion Battery Expansion
Unigrid’s international shipment initiative sets a new standard for Sodium-ion Battery adoption. By leveraging a fab-less, foundry-subscription business model, Unigrid works with manufacturing partners instead of building its own expensive gigafactories. This approach enables the company to expand swiftly in the global market. As a result, Unigrid delivers Grade A Sodium-ion Battery cells from certified foundries directly to customers, packaged efficiently in 40-foot ocean containers.
This strategy allows Unigrid to optimize production capacity, reduce lead times, and satisfy growing international demand for sustainable battery solutions. In 2025, Unigrid moved from pilot-scale production to full-scale commercial exports. This transition marked a major milestone in the Sodium-ion Battery sector, particularly for ports accustomed to handling Lithium-ion (Li-ion) batteries and adapting to the new Na-ion chemistry logistics.
Commercial Milestones and Global Reach
Unigrid’s journey from development to commercialization accelerated after achieving UN38.3 transport certification for its sodium-ion cells. This important certification confirms safe and compliant transportation across international waters. The company delivered the first-ever Na-ion battery exports at several major international ports. These facilities, traditionally tailored for Li-ion batteries, implemented new protocols to handle Unigrid’s innovative battery products.
Unigrid’s ability to safely transport sodium-ion batteries addresses a critical requirement in the renewable energy supply chain. Secure and efficient shipping greatly enhances the appeal of sodium-ion technology for global markets. The National Fire Protection Association (NFPA) is also developing new comprehensive standards, like NFPA 800, to accommodate evolving battery technologies and transportation requirements.
Strategic Partnerships and Commercial Projects
In April 2025, Unigrid formed a strategic partnership with Indexel, an India-based engineering, procurement, and construction (EPC) company. Together, they plan to deploy sodium-ion batteries across various industrial and commercial projects in India. This move positions Unigrid as a critical player in the rapidly growing Asian energy storage market. Later in 2025, Blue Whale Energy, a Singapore-based virtual power plant (VPP) company, announced a partnership with Unigrid. Their collaboration aims to install solar photovoltaic (PV) systems with Sodium-ion Battery storage at commercial and industrial sites throughout Southeast Asia.
These partnerships represent Unigrid’s commitment to expanding access to safer, high-performance, and sustainable battery solutions worldwide. By working with local and regional leaders, Unigrid facilitates the integration of Na-ion storage into diverse clean energy and grid resilience projects.
Future of Sodium-Ion Batteries and Industry Trends
Unigrid continues to lead the Sodium-ion Battery space as commercial demand for alternative chemistries grows worldwide. The energy sector’s shift toward sodium-ion technology stems from sodium’s abundance and the chemistry’s stability, which enables cost-effective, high-performance energy storage. Unigrid remains deeply committed to pushing boundaries in battery technology by refining its NCO cell chemistry and expanding its global reach through innovative business models.
As global energy storage needs intensify, particularly in regions seeking robust and sustainable solutions, Unigrid’s international shipments of Sodium-ion Battery cells play a vital role. With strategic certifications, efficient logistics, and growing commercial partnerships, Unigrid shapes the future of energy storage for utility-scale and industrial applications around the world.
