摘要： The present invention relates to a plasma generating apparatus for a secondary battery. The plasma generating apparatus for the secondary battery comprises a roller part comprising a transfer roller that transfers a separator and a metal member built in the transfer roller, and a plasma generating part comprising a main body spaced apart from the transfer roller and a plurality of electrode members disposed on positions that are spaced apart from each other in a direction of both ends of the main body and partially generating a plasma between the metal member and the main body to form a patterned bonding layer on a surface of the separator, wherein the plurality of electrode members are detachably coupled to the main body to adjust a number of the electrode members coupled to the main body based on a size of the separator.

摘要： The present invention relates to a plasma generating apparatus for a secondary battery. The plasma generating apparatus for the secondary battery comprises a transfer roller that transfers a separator, a metal member disposed within the transfer roller, a plasma generating member that interacts with the metal member to generate a plasma and irradiate the generated plasma onto a surface of the separator, and a protrusion member that causes a portion of the separator closely attached to the transfer roller to protrude and forms an adhesion area, which is adhesive, and a non-adhesion area, which is non-adhesive or less adhesive than the adhesion area, by allowing the plasma to be irradiated onto the adhesion area and no plasma or less plasma to be irradiated onto the non-adhesion area.
