Plasma generator for secondary battery and lamination system comprising the same

A plasma generator for use in manufacturing a secondary battery, the secondary battery comprising an electrode assembly comprising first and second electrodes separated by a separator and the plasma generator comprising:

• a transfer roller configured to transfer the separator;
• and
• a plasma generation part configured to form an adhesive surface having an adhesive force on a portion of a surface of the separator and a non-adhesive surface having no adhesive force on a remaining portion of the surface of the separator,
• wherein the plasma generation part comprises:
• a metal member embedded in the transfer roller;
• a plasma generation member configured to be spaced apart from the transfer roller and to generate plasma by mutual reaction with the metal member and thereby to form the adhesive surface on the portion of the surface of the separator;
• and
• a blocking member located on an outer circumferential surface of the transfer roller and configured to block the mutual reaction between the metal member and the plasma generation member such that the non-adhesive surface is formed on the remaining portion of the surface of the separator,
• wherein an insertion groove is formed in an outer circumferential surface of the transfer roller, and the blocking member is received in the insertion groove of the transfer roller.

A plasma generator for use in manufacturing a secondary battery, the secondary battery comprising an electrode assembly comprising first and second electrodes separator by a separator and the plasma generator comprising:

• a transfer roller configured to transfer the separator;
• and
• a plasma generation part configured to generate plasma and thereby to form an adhesive surface on a portion of a surface of the separator during a transfer of the separator by the transfer roller;
• and
• a blocking member configured to prevent the formation of the adhesive surface on the remaining portion of the surface of the separator during the transfer of the separator by the transfer roller,
• wherein the blocking member is made of a non-conductive material.
