The new‑energy lithium‑ion battery industry imposes stringent production standards on raw material purity, including lithium iron phosphate, ternary materials, graphite, and silicon‑based anodes. 、 Core powder and liquid materials such as conductive carbon black, carbon nanotubes, PVDF, and NMP must have metal impurity levels controlled at the ppb level. Excessive iron impurities in the raw materials can lead to issues like battery self‑discharge and reduced cycle life, thereby compromising both user experience and production stability—making this a critical process step that requires stringent control in lithium‑ion battery material manufacturing.
To meet the lithium‑battery industry’s demands for dust‑free, high‑precision, and ultra‑clean production, intelligent electromagnetic iron removers, slurry magnetic separators, and dry‑powder iron‑removal equipment enable refined impurity removal. These systems deliver a uniform, stable magnetic field that effectively captures trace amounts of ferrous and nickel‑containing metallic contaminants in raw materials, ensuring filtration of high‑purity lithium‑battery feedstocks. The entire process is conducted in a sealed environment with no dust emissions, supporting… 24 It operates continuously and stably for hours, meeting the lithium‑battery industry’s stringent high‑purity production control standards.
Through meticulous control of the iron‑removal process, the metallic impurity content in lithium‑ion battery materials can be effectively reduced, product quality deviations can be minimized, and the consistency and stability of these materials can be ensured, thereby providing process support for standardized mass production by new‑energy companies.
