The path to industrialization for sodium-ion batteries has taken a strategic shortcut—by inheriting the advanced technical systems and mature expertise accumulated by the lithium-ion battery industry over more than two decades.

From cathode materials and electrolytes to electrode processes such as coating, calendering, and slicing, and further to cell assembly steps including winding, liquid injection, and formation, sodium-ion battery production has absorbed the essence of lithium battery manufacturing. This inheritance has not only significantly lowered the barriers to industrialization but also ensured product consistency and reliability, accelerating the shift of sodium battery technology from laboratory to large-scale production.

However, the industrialization of sodium batteries is no mere imitation. In key areas such as cathode material synthesis and electrolyte formulation, sodium battery technology demonstrates unique innovative capacity and technological breakthroughs. At Zoolnasm’s cathode material production line in Zhenjiang, two common industrial by-products—sodium sulfate and ferrous sulfate—undergo a series of sophisticated processes including pre-mixing, grinding, sintering, crushing, blending, demagnetization, and drying. Through these steps, they are transformed into high-performance cathode materials for sodium batteries. While seemingly similar to lithium battery processes, these steps contain unique know-how that has become a core support and competitive advantage for Zoolnasm in leading the industrialization of sodium iron sulfate (NFS) battery technology.

Core Breakthroughs: Innovations in Pre-Mixing, Grinding, and Sintering

As the only enterprise in the industry with both proven large-scale production capacity of 3,000 tons and the capability to construct a second-generation 10,000-ton production line of cathode material, Zoolnasm’s engineering team has integrated all-solid-state pre-mixing technology with a single low-temperature sintering process. This not only reduces energy consumption in key processes to 70% below the industry average but also achieves zero waste emissions and nearly 100% raw material utilization in green production.

Additionally, Zoolnasm has pioneered a horizontal dual-power nano-grinding technology that combines the high efficiency and superior quality of horizontal grinding with a self-developed anti-clogging rapid discharge system. This innovation achieves nanoscale precision in grinding, greatly enhancing material fineness and uniformity, thereby laying a solid foundation for optimized product performance.

Capacity Upgrade: Gearing Up for the Light EV Market in Upcoming Winter

Since commencing production in late October 2023, Zhenjiang Liolnasm has continuously broken through technical bottlenecks. Well-prepared, the company is poised to enter a peak delivery period in September, proactively aligning with the light electric vehicle in upcoming winter.

Sodium-ion batteries' superior performance in low temperatures secures a unique edge for winter applications, making a stable supply of materials critical to fulfilling market demand. These high-quality cathode materials will be chiefly used in cells for electric two-wheelers and low-speed electric vehicles, targeting northern low-temperature markets. They are set to deliver a safer and more reliable mobility experience for end-users in cold.

Against this backdrop, Zoolnasm plans to publicly unveil the mass production process of NFS cathode materials at the Liolnasm facility in Zhenjiang in early September. The event will showcase:

How the industry-first nano-grinding system enables efficient and high-quality production

How the “green alchemy” turns industrial waste into valuable materials

The current production and delivery status of NFS cathode materials

Join us on this fascinating journey of turning industrial waste into treasure—witness a true spectacle of green alchemy!
