Jiuwu Hi-Tech: Cracking the Code of Solid-State Battery Commercialization with Innovation DNA

On March 18th, the 2nd All-Solid-State Battery Technology Exchange Conference opened in Hefei. This conference focused on core topics such as the large-scale mass production of all-solid-state batteries, breakthroughs in key materials, and the application of dry electrodes, exploring pathways to industrial breakthroughs and discussing technology implementation solutions. As a pioneer in Chinese ceramic membrane technology with a strong "innovation gene," Jiuwu Hi-Tech participated in the conference with its latest oxide solid electrolyte materials and high-purity lithium sulfide products, showcasing its innovative leap from "membrane separation" to "solid-state energy" and injecting strong momentum into accelerating the industrialization of all-solid-state batteries with its core technological strength.

Breaking Technical Barriers: Mastering Solid-State Electrolyte & High-Purity Lithium Sulfide Production

Currently, all-solid-state batteries, with their core advantages such as high safety, high energy density, and wide temperature range adaptability, are becoming a disruptive technology for next-generation power and energy storage batteries, and are also an important support for achieving the "dual carbon" goal. However, their large-scale deployment still faces several core bottlenecks: insufficient consistency in the mass production of oxide solid electrolytes, difficulty in balancing ionic conductivity and stability, and high cost, complex process, and high impurity content in lithium sulfide preparation. The shortage of key materials has become an important factor restricting the development of the industry.

Facing common challenges in the industry, Jiuwu Hi-Tech, relying on its independent R&D system and through continuous technological breakthroughs, has successfully overcome the core barriers in the preparation of oxide solid electrolytes, developing proprietary processes for preparing lithium lanthanum zirconium oxide (LLZO), lithium titanium aluminum phosphate (LATP), and high-purity lithium sulfide (Li₂S) powders. Breaking through the limitations of traditional processes, the company has initially established a powder product supply system that can flexibly adapt to the application needs of downstream cell and separator manufacturers. Currently, it has achieved continuous and stable batch supply to downstream enterprises, marking a crucial step towards industrialization.

Core Strength: High Ionic Conductivity Laying a Solid Foundation for Performance

At the 2nd All-Solid-State Battery Technology Exchange Conference, Jiuwu Hi-Tech highlighted the technical advantages of its oxide solid-state electrolytes, fully demonstrating its innovation capabilities. The exhibition attracted numerous attendees, research institutions, and industry chain partners, who visited the booth for in-depth discussions and potential collaboration. The company has independently developed a synergistic "low-temperature solid-phase + atmosphere sintering" process, combined with multi-element doping modification technology, enabling precise control over the material's crystal lattice structure. The key advantages are:

● LLZO materials achieve a room-temperature ionic conductivity of up to 1.0 mS/cm, while LATP materials reach an even higher 1.30 mS/cm. Key performance indicators remain among the top levels in the industry, creating a "high-speed channel" for efficient lithium-ion conduction and effectively ensuring the battery's charge-discharge efficiency and cycle stability;

● By subjecting standard LLZO powder to surface modification treatment, the generation of alkaline substances can be effectively inhibited, enabling it to remain stable for extended periods in air and making it suitable for aqueous slurry systems.

Based on its accumulated expertise in the field of oxide solid-state electrolytes, the company has further independently developed the synthesis and large-scale production process for lithium sulfide. This marks Jiuwu Hi-Tech's successful strategic expansion from oxide to sulfide key materials, further refining its industry chain layout in the solid-state battery materials sector. The main advantages of the products are:

● The lithium sulfide product boasts a purity of no less than 99.8%, with 99.9% purity available upon customer request. It features low impurity content and excellent batch-to-batch stability, meeting the synthesis requirements for sulfide solid-state electrolytes (such as LGPS, LPSCl, etc.).

● It can provide high-quality raw material support for downstream customers, promoting the transition of sulfide electrolytes from the laboratory to large-scale applications, and facilitating the industrialization of next-generation, high-energy-density, and high-safety all-solid-state batteries.

Empowering the Industry: Cross-Border Innovation Never Stops, Co-Building a New Solid-State Battery Ecosystem

From a leader in ceramic membrane technology to an innovator in solid-state battery materials, Jiuwu Hi-Tech's cross-industry breakthrough is not simply an extension of its business scope, but rather a reuse and upgrade of its core technologies. Leveraging its refined R&D and control capabilities in membrane materials and lithium-ion adsorption materials, along with nearly thirty years of experience in sintering and processing inorganic materials, the company deeply integrates the entire process of solid-state battery material R&D and production, fully releasing its technological synergy advantages. This provides solid material support for all-solid-state batteries to move from the laboratory to large-scale mass production.

This participation is not only a comprehensive showcase of the company's achievements in solid-state battery technology, but also a vital opportunity to deepen exchanges, expand collaboration, and pursue shared development with industry peers. Moving forward, Jiuwu Hi-Tech will continue to focus on the solid-state battery materials sector, driving industrial upgrading through technological innovation. The company is committed to helping China's all-solid-state battery industry seize a leading position in the global market and contribute "Jiuwu's strength" to the high-quality development of the new energy industry.
