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

The celebration of Yifu Intelligent Hubei New Industrial Park is about to kick off. The forum's focus has shifted from "main engine factory and material factory" to a lower level bead - when LFP, sodium power, silicon carbon anode, and solid electrolyte all point to "nanoscale, narrow distribution, zero pollution", grinding media is no longer a consumable, but a "precision anchor" for powder technology.

At this round of "Medium Defined Powders", we invited a ceramic material operator who has spent half his life on zirconia microbeads - Lee Ju-sung, the representative director of CENOTEC in South Korea, has a Ph.D. in Engineering. He joined Sano as a founding team member in 1999, and has served as director of the R&D center and senior executive of the production division. He will serve as a representative director in 2023. He is officially confirmed to attend this forum and the housewarming celebration of Yifu Intelligent Hubei New Industrial Park, and will bring a keynote report"Medium builds the foundation, and the powder reaches the future: the application, selection and process value of zirconium beads in new energy materials". From 0.05mm microbeads to GWh-level cathode production lines, he will explain thoroughly "how to select beads, how to calculate losses, and how to stabilize data."

The doctor of engineering who made "ceramic microbeads" into the base of Korean battery materials

Dr. Lee Ju-sung has a background in materials engineering. When Sano was founded in 1999, he was deeply involved in the construction of the technical system as a founding team member, and successively took charge of the R&D center and production division. Took CENOTEC from "replacing imported ceramic beads" to the only high-density zirconia grinding media company in South Korea and the world's leading company: boosted the company in 2016 KOSDAQ is on the market, covering a full range of yttrium-stabilized (CZY), cerium-stabilized (CZC), and zirconium-aluminum composite beads, with self-wear control to the ppm level, and sphericity and particle size distribution meeting nano-grinding requirements.

What he presides over is not only the "bead formula", but the entire set of media technology: electrolyte titration molding, high-temperature precision sintering, tetragonal phase stability, and metal ion precipitation control. In recent years, he has pushed Sano to transform from a "media supplier" to a "battery process solution partner" - deploying cathode ceramic additives, participating in the KEIT national project to develop cathode interface stabilizers, and co-building the CENOTEC & INFOR Global Grinding Technology Center (G-GTC) with Yifu, twisting "equipment + media + process" into the same technical axis. In his eyes, there are no "ordinary zirconium beads", only "the optimal solution at a specific linear speed, specific solid content, and specific slurry."

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

Dr. Li Zhucheng's report"Medium builds the foundation, and the powder reaches the future: the application, selection and process value of zirconium beads in new energy materials", just in time to make up for the most easily ignored, but most fatal piece of the puzzle of this forum:

The application layer - LFP needs to have D50 stably pressed to the 120nm level, the sodium electric hard carbon needs to open pores without breaking beads, the silicon carbon negative electrode needs to suppress magnetic foreign matter, the solid electrolyte needs to be sub-micron homogeneous and not introduce Zr contamination; if the medium is wrongly selected, all previous material designs will be reset to zero.

Selection layer - not "the smaller, the finer": the vertical machine is equipped with 0.1–0.3mm yttrium-zirconium beads at high linear speed, and the horizontal machine is equipped with 0.4–0.6mm at medium speed. Coarse grinding and depolymerization → fine grinding and homogenization → ultra-fine shearing require three-stage series connection; the filling rate, separation screen, temperature rise, and crushing rate must be calculated together.

Process value layer - the self-abrasion of zirconium beads directly turns into slurry impurities, and the dielectric loss curve is the batch CV value curve. The joint experiment between Sano and Yifu proved that by changing the media of the same sand mill, the particle size efficiency can be increased by 40%, and the cost of equipment wear and shutdown for bead replacement can be simultaneously reduced.

For the material factory, it answered "Why is the particle size distribution of the same formula in different factories twice as different?"; for the equipment factory, it reminded that the separation system must adapt to the microbead working conditions; for Yifu, it means that the new park production line must preset the "media database" into the control system. The starting point of powder's long-term development is the foundation of medium.

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. Let’s listen to Dr. Li Zhucheng explain clearly from the perspective of South Korea’s Sano headquarters “how to select beads for new energy powder, how to control losses, and how to turn media into process assets”; and also see how Yifu’s new production line uses the same logic as G-GTC to change the grinding results from “experience-based” to “auditable”. The relocation is not a ribbon-cutting, it is Yifu and Sano working together to nail the precision base of the Sino-Korean grinding industry chain in Gucheng.

Start a new journey with you in Gucheng, see you there!
