Myungseong TNS Obtains Patent for High Heat-Resistant Secondary Battery Separator Coating Equipment

Patent Registration for Coating Device Developed through National Project Completion

[Asia Economy Reporter Eunmo Koo] Myeongseong TNS, a specialized manufacturer of separator manufacturing equipment, has obtained a patent for a coating device developed through a government-funded project.

On the 9th, Myeongseong TNS announced that it has completed the registration of a patent for a separator coating manufacturing device for secondary batteries. The patent pertains to a secondary battery separator coating device that forms a patterned coating layer on the separator surface, enabling excellent electrolyte ion transfer and enhanced heat resistance. Development began after being selected for a government project led by the Small and Medium Business Corporation in August 2018.

The separator is a thin film that separates the anode and cathode inside a secondary battery, allowing lithium ions to move through its micropores. Since contact between the anode and cathode can lead to fire or explosion due to overheating, the separator is a material directly related to the safety of secondary batteries.

A representative from Myeongseong TNS explained, “By applying an inorganic particle coating with heat resistance, the heat resistance of the separator is enhanced, thereby improving the safety of secondary batteries. The patented technology disperses thermal contraction forces through the patterned coating layer, maintaining the structural stability of the separator and improving thermal stability.”
