Purity control in the lithium battery ternary materials industry

A certain lithium battery material enterprise specializes in the production of ternary cathode materials. These materials have extremely high requirements for iron impurity content. Excessive iron impurities will seriously affect the cycle performance and safety of the battery. Previously, due to iron impurities carried by raw materials and equipment wear during the production process, the iron content in ternary materials often exceeded 30ppm, which did not meet the production standards for high-end batteries. After the introduction of the dry powder magnetic separator, the equipment, with its innovative coil design and special medium mesh, can precisely adsorb the tiny iron particles in the materials. After testing, the iron content of the treated ternary material was stably controlled below 5ppm, meeting the demands of high-end customers. The product qualification rate has risen from 70% to 95%, and the enterprise has successfully entered the high-end lithium battery supply chain. The order volume has increased by 50% year-on-year, and the annual sales have risen by 8 million yuan.
