November 16-17, 2026, Gucheng, Xiangyang, Hubei.

On the day of the celebration of Yifu Intelligent Hubei New Industrial Park, the forum focused on the hardest piece of the sodium-ion battery puzzle - the positive electrode. When the industry shifts the narrative of sodium batteries from "replacement of lithium batteries" to "energy storage + real cost reduction of two-wheeled vehicles", the low-cost, high-voltage, but extremely difficult to stabilize NFS in the polyanion system is moving from papers to production lines.

In this round of "finding the main line for sodium cathode", we invited a senior researcher who has brought NFS from the laboratory to the pilot line - Professor Liang Guangchuan of Hebei University of Technology. He is currently the director of the Institute of Energy and Environmental Protection Materials at Hebei University of Technology and concurrently serves as the chairman of Tianjin Xianzhong New Energy. He has been deeply involved in lithium-ion and sodium-ion battery cathode materials for a long time. He has presided over the national "863" plan, science and technology support plans and key special projects. More than ten achievements have been industrialized. He has published more than 100 SCI papers and authorized patents. He is officially confirmed to attend this forum and the housewarming celebration of Yifu Intelligent Hubei New Industrial Park, and will give a keynote report."Battery R&D and Industrialization Based on NFS Sodium-Ion Battery Cathode Materials". From the crystal structure of sodium ferric sulfate to whether the battery core can run for two thousand cycles, he will open up the chain of "material-slurry-battery core" at once.

A practical person in industry, academia and research who turned "NFS from a chemical formula into a cell"

Liang Guangchuan, a researcher and doctoral supervisor at Hebei University of Technology, a leading industrial talent in Taishan, Shandong Province, currently the director of the Institute of Energy and Environmental Protection Materials, and the chairman of Tianjin Xianzhong New Energy and Huzhou Xianzhong New Energy. His research is not at the conceptual level: in his early years, he worked on high-pressure lithium iron phosphate and lithium iron manganese phosphate modulated structures. In recent years, he has focused on sodium electropolyanions - especially the Alluaudite-type Na₂₊₂ₓFe₂₋ₓ(SO₄)₃ (NFS) system.

He led the team to solve the most painful things about NFS: the intrinsic conductivity is low, so composite carbon sources + CNTs are used to build a conductive network; the slurry is easy to agglomerate and the pole piece resistance is high, so the spray drying and dispersion process is optimized; water-based synthesis is afraid of moisture and the phase purity is difficult to control, so non-stoichiometric ratios and surface coatings are used to increase the cycle. Team data shows that the NFS/CNT/AB composite cathode has a reversible capacity of approximately 102 mAh/g at 2C, and the capacity retention rate exceeds 94% after 200 cycles. He is not a scholar who "turns in the paper after sending it in", but a person who takes the material properties, pole piece technology, battery certification (CE, UN38.3) and the two-wheeled vehicle scene together.

In-depth echo with the theme of the forum "New Energy and New Materials"

Liang Guangchuan's report"Battery R&D and Industrialization Based on NFS Sodium-Ion Battery Cathode Materials" just puts the main axis of this forum "new materials driving new batteries" at the most realistic industrialization threshold of sodium electricity:

Material layer - NFS relies on the induction effect of SO₄²⁻ to push the Fe³⁺/Fe²⁺ potential to 3.8V. The raw materials only use sodium, iron, and sulfur. The theoretical cost is extremely low, but poor conductivity, moisture absorption, and hybridization are the three hurdles; carbon coating, CNT bridging, and non-metering ratio control are the keys to turning "cheap" into "usable".

Process layer - NFS powder is extremely sensitive to grinding and dispersion: the particle size distribution is one inch wider, and the resistance of the pole piece increases; the nano-level homogeneity, magnetic foreign matter control, and slurry rheological stability of the previous sand grinding directly determine the cell rate and cycle.

At the industrial level - the real battlefield for sodium power is two- and three-wheel vehicles, start-stop, and distributed energy storage, which are sensitive to cost and lifespan and relatively energy-tolerant. If NFS can be stably mass-produced, it will push the cost of sodium battery cells to a position close to that of lead-acid, and its cycle will far exceed that of lead-acid.

For the material factory, it answered "How do polyanions cross the pilot plant death valley?"; for the equipment factory, it reminded the sand grinding system to be adapted to water-sensitive, high solid content, and narrowly distributed sodium electroslurry; for Yifu, it meant that the Xinyuan production line should make the "dispersion-coating-drying" of NFS into a reproducible process package. The trump card for the industrialization of sodium electricity lies in the consistency of the cathode powder.

In the golden autumn of November, Gucheng’s new garden opens

From November 16th to 17th, the new park and forum opened simultaneously in Gucheng, Xiangyang, Hubei! It is recommended that all friends who make sodium cathodes, hard carbon anodes, two-wheeled vehicle batteries and energy storage systems reserve a seat: Listen to Liang Guangchuan explain clearly "how NFS can transform from material formula to industrial asset" from the two-way perspective of Hebei University of Technology and Xianzhong production lines; also see how Yifu's new production line uses high-precision dispersion to catch the industrialization pace of polyanion cathodes. Relocation is not a ribbon-cutting, it is Yifu and a generation of sodium-electronics materials people who have worked together to polish China's sodium-electronics from being "speakable" to "running steadily."

Billion starts a new journey, a rich future, Gucheng New Park will see you there!
