Daebo Magnetic, a specialist company in electromagnetic separators (EMF), announced on the 22nd that it has begun developing the world's highest magnetic force unit electromagnetic separator. The ultra-high-performance electromagnetic separator being developed this time can effectively remove even fine magnetic particles.
An electromagnetic separator is equipment that removes trace amounts of iron contained in the cathode and anode materials of lithium secondary batteries. If magnetic components are not properly removed, battery quality deteriorates, increasing the risk of fire. Therefore, the iron removal process is essential to improve the safety and maximize the yield of secondary batteries.
The core technology of the electromagnetic separator is to distribute a uniform magnetic field per unit area. This helps reduce quality variation in cathode materials. Since it is necessary to simultaneously achieve a high magnetic force level and a uniform magnetic field distribution, many companies face difficulties in developing high-performance electromagnetic separators.
Based on over 50 years of unparalleled technology in the electromagnetic field, Daebo Magnetic succeeded in developing the world's first wet electromagnetic separator. It supplies electromagnetic separators worldwide, including Europe and North America, and is the only company globally capable of manufacturing both dry and wet electromagnetic separators. Additionally, Daebo Magnetic holds references for supplying high-performance electromagnetic separators to global secondary battery and cathode material companies such as LG Energy Solution, Samsung SDI, POSCO Future M, LG Chem, EcoPro BM, CATL, and BYD.
Global secondary battery companies are increasingly demanding the advancement of electromagnetic separators to enhance battery safety and maximize productivity. The development of this ultra-high-performance electromagnetic separator also began at the request of customers. The company explained that it is simultaneously pursuing the formation of a much higher magnetic field compared to existing equipment and the enlargement of the equipment.
A Daebo Magnetic representative stated, “The newly developed electromagnetic separator can remove ultra-fine iron components and reduce impurity content to 15ppb (parts per billion), which is expected to greatly contribute to improving the safety of secondary batteries. Since it utilizes a high magnetic field, it also allows for equipment enlargement, which has the advantage of increasing production efficiency.”
