A Silicon Removal from Material Liquid Project of a New Energy Company in Zhejiang

Project situation and issues: With the continuous application of nickel salt products in lithium-ion battery cathode materials, the requirements for impurity content are also improving. In the process of producing high-quality nickel sulfate material liquid for new energy enterprises, impurities need to be removed to reduce silicon content.

Processing technology and advantages: Adopting adsorption technology by using adsorbent HP4800, the silicon content in the nickel sulfate material liquid will be deeply removed from ~30mg/L to~7mg/L, improving the purity of the material liquid and enhancing product competitiveness. The resin in this process has high selectivity for silicon removal, minimal interference from other coexisting anions, small footprint, high degree of system automation, and simple to operate.
