Publication number: 20230420721Abstract: A system and method for manufacturing a secondary battery, in which air is suctioned in an opposite direction of a transfer direction inside a loading part to prevent a radical unit, which freely drops at an initial speed in the transfer direction, from colliding with the loading part, thereby reducing folding short defects that occur in a subsequent process. The system for manufacturing the secondary battery includes a transfer part configured to transfer a radical unit, a loading part configured to allow the radical unit transferred by the transfer part to drop in a direction of gravity so as to load the radical unit, and an intake part configured to suction air inside an inner space of the loading part from a side surface of the loading part.Type: ApplicationFiled: March 4, 2022Publication date: December 28, 2023Applicant: LG Energy Solution, Ltd.Inventors: Jeong Min Lee, Shin Hwa Lee, Jae Woong Yoo, Eun Kyeong Lim
