From Ceramic Membranes to New Materials: Jiuwu Hi-Tech’s Growth Path

For nearly three decades, Jiuwu Hi-Tech has focused on advanced materials and separation technologies. Building on its expertise in ceramic membranes, the company has expanded into four key technology areas: ceramic membranes, organic membranes, adsorbents, and solid-state electrolytes.

This development represents a shift from a single technology focus to a broader technology portfolio. By combining advanced materials with practical industrial solutions, Jiuwu Hi-Tech continues to create new opportunities in high-end manufacturing and green technologies.

How Did Jiuwu Hi-Tech Develop China’s Ceramic Membrane Technology?

In the 1990s, China’s ceramic membrane market was mainly dominated by European and American companies. High costs, technology restrictions, and dependence on overseas suppliers created major challenges for domestic industries.

Led by Academician Xu Nanping, the founding team of Jiuwu Hi-Tech undertook the national “Ninth Five-Year Plan” key technology project. Without existing designs or mature manufacturing processes to follow, the team conducted extensive research on ceramic powders, membrane structures, and production technologies.

After years of innovation, Jiuwu Hi-Tech successfully developed China’s first domestically produced ceramic membrane tube, filling a technological gap and establishing an independent foundation for China’s ceramic membrane industry.

How Do Organic Membranes Expand Jiuwu’s Water Treatment Solutions?

As one of the few companies in the industry with core technologies in both ceramic and organic membranes, Jiuwu Hi-Tech has developed a complete range of spiral-wound organic membrane products, covering microfiltration, ultrafiltration, nanofiltration, and reverse osmosis.

By combining ceramic membranes with organic membranes, Jiuwu Hi-Tech can develop flexible treatment solutions based on different water conditions, achieving an effective balance between performance and cost.

In applications such as municipal water treatment and industrial wastewater zero liquid discharge, these integrated membrane solutions can achieve up to 99.9% microorganism removal and wastewater recovery rates above 92%. They also help extend membrane service life, reduce maintenance requirements, and provide reliable solutions for water supply, wastewater treatment, and water reuse.

How Is Jiuwu Hi-Tech Advancing Lithium Extraction Technology?

To address the challenges of China’s salt lake lithium resources, including high magnesium-to-lithium and sodium-to-lithium ratios, Jiuwu Hi-Tech has developed an integrated “adsorption + membrane” technology solution.

The company has independently developed fourth-generation aluminum-based and titanium-based lithium adsorbents with high selectivity and adsorption capacity. Compared with third-generation products, these adsorbents improve performance by 30–50%, achieve lithium recovery rates above 90%, and provide impurity removal performance more than 20% higher than comparable products.

These technologies have reduced lithium extraction costs by 30–40% and lowered energy consumption by more than 50% compared with overseas technologies. They have also been successfully applied in one of China’s largest salt lake lithium extraction projects currently under construction, supporting the transition from resource-based extraction to stable industrial production and strengthening lithium resource security.

What Has Jiuwu Hi-Tech Achieved in Solid-State Electrolytes?

Based on nearly three decades of experience in inorganic functional materials, Jiuwu Hi-Tech has developed advanced oxide solid-state electrolyte materials, including LLZO and LATP, with performance reaching or exceeding mainstream industry standards.

These materials have been supplied in multiple batches to leading domestic battery manufacturers. In addition, Jiuwu Hi-Tech’s lithium sulfide material, a key component for sulfide solid-state electrolytes, has achieved a purity level of 99.9%.

The company has established metric-ton-scale production capabilities for solid-state electrolyte powders and developed a product portfolio covering powders, slurries, and dense ceramic sheets. Pilot production lines are currently being accelerated to further strengthen Jiuwu Hi-Tech’s capabilities in key solid-state battery materials and support the development of safer and more reliable next-generation batteries.

What New Applications Has Jiuwu Hi-Tech Developed Through Innovation?

Jiuwu Hi-Tech continues to improve its technologies and expand their applications. Its tubular ceramic membranes cover filtration needs from microfiltration to ultrafiltration. The high-packing-density column ceramic membrane increases membrane area per unit volume by three times, enabling broader applications in municipal drinking water treatment.

Meanwhile, silicon carbide ceramic membranes provide excellent performance under extreme conditions and can operate reliably across a wide temperature range from -20°C to 800°C.

With high filtration accuracy, strong adaptability, and long service life, Jiuwu Hi-Tech’s membrane technologies have been widely applied in areas such as chlor-alkali brine purification, biopharmaceutical processing, and industrial wastewater zero liquid discharge.

How Does Jiuwu Hi-Tech Strengthen Innovation Capabilities?

Being recognized as a Manufacturing Single Champion Enterprise has further strengthened Jiuwu Hi-Tech’s innovation capabilities and attracted more support for research and development.

The company has taken the lead in establishing the National High-Performance Membrane Materials Innovation Center and maintains close cooperation with leading universities, including Nanjing Tech University. This collaboration connects fundamental research with industrial applications and accelerates the commercialization of new technologies.

Jiuwu Hi-Tech invests 5–8% of its annual revenue in research and development. The company has received four National Science and Technology Progress Awards, one National Technology Invention Award, and other recognitions, including Outstanding Enterprise of Jiangsu Province.
