Zoolnasm, established in January 2021 and based in Suzhou, Jiangsu Province, is a leading Chinese innovator in sodium-ion battery technology. The company focuses on developing low-cost, high-performance sodium-ion batteries for energy storage and electric mobility applications. A globally recognized National High-Tech Enterprise and honored as a Potential Unicorn in Jiangsu Province, Zoolnasm combines cutting-edge R&D with scaled production to advance sustainable energy solutions.
Its portfolio includes sodium iron sulfate (NFS) battery systems, optimized for cost efficiency, long lifecycle, and adaptability to extreme temperatures. The company has successfully commercialized its technology for applications ranging from automotive power systems to grid storage, with strategic partnerships and certifications underscoring its industry credibility. Zoolnasm’s vertically integrated operations—from material synthesis to system integration—enable precise quality control and competitive pricing, positioning it at the forefront of the transition to carbon-neutral energy systems.
Battery Technology
Zoolnasm’s core innovation lies in its sodium iron sulfate (NFS) battery technology, the first industrialized system of its kind globally. This technology relies on three proprietary cathode material preparation methods, patented by the company across over 130 authorized patents. Key advancements include a “green manufacturing” process combining solid-state premixing with low-temperature sintering. This method cuts energy consumption for cathode production to less than 70% of lithium-ion equivalents, achieving near-total raw material utilization (99%) and eliminating emissions.
The company’s NFS cathode materials are produced at a thousand-ton scale, a capability unique to Zoolnasm. Its NFS-50 battery cell exemplifies the technology’s performance: it supports a 10C discharge rate, operates reliably from -20°C to 60°C, and achieves minimal temperature rise (13°C during 10C discharge). By replacing costly lithium with abundant sodium compounds, Zoolnasm estimates potential cost reductions of up to 50% compared to lithium-ion batteries, while ensuring high safety and longevity. The technology is further adaptable for automotive applications, including hybrid power systems and low-voltage vehicle batteries, and is being tested for integration into electric vehicles like BYD’s Seagull model.
Recent Projects
Recent milestones include the launch of Zoolnasm’s first large-scale manufacturing facility in Guangde, Anhui Province, which began construction in November 2023. This $1.4 billion project aims for 20 GWh annual cell production capacity and 10 GWh system integration by its completion. In October 2024, the company secured a four-year supply contract worth $28.1 million with a major international auto parts manufacturer, marking progress in automotive sector penetration. Deliveries to two car companies have already commenced, validating NFS batteries’ compatibility with mobility applications.
Zoolnasm also received the Gold Award at the 2024 BRICS Industrial Innovation Competition for its NFS technology’s contributions to low-carbon systems. These developments underscore the company’s expansion into global markets and its commitment to scaling production while maintaining environmental standards.
Investors
Zoolnasm has attracted substantial investment since its founding, including a pre-A round led by Shenzhen Country Garden Venture Capital. Notable investors include Kunlun Fund, Jiangsu Huahai Financial Holding Group, Zhonghe Investment, and SND Financial Holdings. Significant funding rounds include a $60 million investment from Pylon Technologies in June 2023 and a $100 million injection from Suzhou High-Tech Venture Capital Group and affiliates in December 2022. These financial partnerships support ongoing R&D, production scaling, and strategic expansion.
