Anode-free sodium battery technology is moving closer to market as Mana Battery and Saft launch a Joint Development Agreement to co-develop, test, and commercialize advanced cells for defense, aerospace, rail, data centers, and industrial backup power. The agreement combines Mana Battery’s liquid electrolyte platform with Saft’s large-scale manufacturing and qualification expertise. As a result, both companies aim to accelerate a safer, lighter, and more sustainable battery option for mission-critical uses.
Anode-free sodium battery partnership targets commercialization
Mana Battery, a startup spun out from the University of Colorado Boulder, has partnered with Saft, the battery manufacturer owned by TotalEnergies. Together, the companies will focus on next-generation anode-free sodium-ion batteries. Their goal is clear: bring this chemistry from development into real-world deployment.
The partnership matters because it aligns advanced materials science with industrial production. Mana Battery contributes its electrolyte innovation. Meanwhile, Saft adds decades of experience in battery manufacturing, testing, and qualification for demanding sectors. Therefore, the collaboration could speed up product readiness for customers that need reliable energy storage under harsh conditions.
Saft Chief Technology & Innovation Officer Kamen Nechev said sodium-ion chemistry holds strategic value for the industries the company serves. He also noted that anode-free designs represent a promising frontier. In addition, he said Mana Battery’s electrolyte platform complements Saft’s strengths in cell design and production. That combination supports the plan to deliver safe, high-performance batteries to defense, aerospace, rail, datacenter, and industrial UPS customers.
How anode-free sodium battery design improves performance
Anode-free sodium battery cells simplify battery architecture. Instead of using graphite or hard carbon on the negative current collector, the design removes that host material. As a result, the cell becomes lighter and simpler to manufacture.
During the first charge cycle, sodium ions move from the cathode through the liquid electrolyte. Then they plate directly onto the current collector as a thin layer of metallic sodium. This process creates the anode only when needed. Because of that, the battery avoids extra bulk and unnecessary material use.
When the cell discharges, the metallic sodium dissolves back into ions and returns to the cathode. This charge and discharge mechanism supports a compact structure. Moreover, it helps increase energy density while lowering manufacturing complexity.
The chemistry also benefits from sodium’s abundance. Unlike battery systems that rely on lithium, cobalt, or nickel, sodium-based designs can support a more sustainable supply chain. In turn, that can reduce carbon footprint concerns linked to material sourcing. For industries focused on domestic supply resilience and long-term procurement, that advantage is important.
Anode-free sodium battery benefits for defense and data centers
This agreement centers on applications that demand safety, reliability, and strong performance in extreme environments. For example, defense systems often need sub-zero cold starts, heat resistance, and long standby life. According to the companies, the new battery platform aims to meet those requirements.
Data centers also stand out as a major use case. As AI infrastructure expands in 2026, operators need dependable backup power with strong safety characteristics. Therefore, anode-free sodium battery systems could offer a thermal-runaway-safe option for hyperscale facilities and industrial UPS installations.
The technology may also fit aerospace and rail markets. In those sectors, lower weight can improve efficiency and system design. At the same time, high safety margins make the chemistry attractive for replacing heavier legacy lead-acid batteries. Consequently, manufacturers and operators could gain a lighter energy storage solution without sacrificing reliability.
Anode-free sodium battery platform combines two strengths
Tyler Evans, CEO of Mana Battery, said Saft is the right partner for qualifying cells for the world’s most demanding customers. He added that the agreement validates the maturity of Mana Battery’s electrolyte and anode-free platform. Furthermore, he said the deal creates a fast path from laboratory development to field deployment.
That point matters because commercialization depends on more than chemistry alone. Companies must scale production, validate safety, and prove performance across use cases. Saft brings established customer relationships and qualification pathways in defense, aerospace, rail, and industrial markets. Meanwhile, Mana Battery contributes a specialized platform built for high energy density and supply-chain sustainability.
Why the anode-free sodium battery market matters in 2026
Battery buyers in 2026 want high performance, safer operation, and resilient sourcing. This partnership addresses all three goals. First, the anode-free design can raise energy density by removing inactive material. Second, sodium supports a broader and more abundant raw material base. Third, the companies are targeting sectors where reliability and safety carry premium value.
If Mana Battery and Saft succeed, they could help expand the commercial role of sodium-ion technology in critical infrastructure. More importantly, they could show that simpler battery architecture can deliver strong results in demanding environments. For defense programs, aerospace systems, rail equipment, and AI data centers, that promise makes this agreement one to watch in 2026.
