  • Patent number: 11923492
    Abstract: An apparatus for manufacturing a bagged electrode includes a conveying unit, a first bonding unit, a second bonding unit, and a separating unit. The conveying unit conveys an electrode in a manner interposed between a pair of long separator materials unwound from a pair of rolls. The first bonding unit bonds the pair of long separator materials outside the electrode along a conveyance direction without stopping conveyance of the electrode and the pair of long separator materials. The second bonding unit bonds the pair of long separator materials outside the electrode along a direction intersecting the conveyance direction without stopping conveyance of the electrode and the pair of long separator materials. The separating unit cuts the pair of long separator materials along the direction intersecting the conveyance direction to cut off the bagged electrode without stopping conveyance of the electrode and the pair of long separator materials.
