300t/a high-performance spherical nickel hydroxide project passed certification
The "300t/a High-Performance Spherical Nickel Hydroxide" developed by the Beijing Nonferrous Metal Research Institute has successfully passed technical evaluation. Experts have recognized that the project has introduced a novel, integrated wet process with independent intellectual property rights. This innovative method enables the entire process of crystal nucleus formation, crystal growth, and particle size control to be carried out within a single reactor in a continuous system. The technology uniquely manages colloidal formation, rapid crystal growth, and periodic nucleus generation, while also controlling key parameters such as draft tube design and pH levels. Additionally, on-line inspection techniques ensure consistent quality and stable performance across batches, making this process significantly more advanced than existing technologies both domestically and internationally. The technology has earned four national invention patents.
This high-performance spherical nickel hydroxide engineering technology is characterized by automated control, closed-loop continuous production, environmental friendliness, and efficient resource utilization, meeting strict national environmental standards. According to inspections by the national statutory unit, the physical and chemical properties as well as electrochemical performance of the product have reached international advanced levels. The product has been tested and approved by renowned domestic and international companies, including Matsushita Electric Co., Ltd., and is now being purchased in large quantities.
With this breakthrough technology, 20 continuous production lines for 300t/a high-performance spherical nickel hydroxide have been established, resulting in an accumulated capacity of 6,000t/a. By July 2005, the total production value had exceeded 1 billion yuan, and foreign exchange earnings reached 8 million U.S. dollars. The technology has delivered substantial economic and social benefits, demonstrating its strong market potential and industrial significance.
