An apparatus for manufacturing an electrode assembly includes a separator supply unit, a table, a separator guide, and first and second upper adhesive supply units. The separator supply unit is configured for supplying a separator sheet from which a separator is formed. The table is configured for supporting a plurality of electrodes and sections of the separator sheet. The separator guide is configured for guiding the separator sheet to fold in a particular folding direction. The first and the second upper adhesive supply units are configured for applying an adhesive to respective sections of the separator sheet. The table is configured for rotating in a first rotational direction such that a first table side of the table moves closer to the second upper adhesive supply unit and in a second rotational direction such that a second table side of the table moves closer to the first adhesive supply unit.

Electrode assembly and apparatus and method for manufacturing the same

An apparatus for manufacturing an electrode assembly includes a separator supply unit, a table, a separator guide, and a pair of upper adhesive supply units. The separator supply unit is configured for supplying a separator sheet from which a separator is formed. The table is configured for supporting an electrode and a portion of the separator sheet. The separator guide is configured for guiding the separator sheet to fold in a particular folding direction. The pair of upper adhesive supply units are configured for applying an adhesive to at least a part of an uppermost electrode supported by the table. The separator guide and the pair of upper adhesive supply units are configured for translation over and relative to the table. The electrode assembly is manufactured by a process using the apparatus.

Discussed is a notching apparatus for a secondary battery that includes: a lower mechanism comprising a die and a die holder to which the die is fixed, the die engaging an electrode provided with a coating portion and a non-coating portion; a stripper including a first stripper pressing the coating portion and a pair of second strippers pressing and fixing the non-coating portion; an upper mechanism including a punch provided between the pair of second strippers and provided with a cutting blade cutting the non-coating portion disposed between the pair of second strippers and a punch holder allowing the punch to move in a direction of the lower mechanism; and a pressing member pressing the non-coating portion disposed between the pair of second strippers to increase in tension force when the non-coating portion is cut by the punch.
