Abstract

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.
