The present invention relates to a pressing apparatus capable of uniformly pressing an object to be pressed using a pressure adjustment portion having a fluid contained therein irrespective of the shape of the object and a pressing method using the same.

Pressing apparatus including fluid and electrode and electrode assembly manufacturing method using the same

Discussed is an apparatus for manufacturing a unit cell of a battery, the apparatus including: a center electrode reel from which a center electrode is unwound; an upper separator reel from which an upper separator laminated on a top surface of the center electrode is unwound; a lower separator reel from which a lower separator laminated on a bottom surface of the center electrode is unwound; and a magnetic force generation part disposed above or below a first laminate to apply magnetic force to the first laminate, the first laminate including the lower separator, the center electrode, and the upper separator that are sequentially laminated.

Apparatus and method for manufacturing unit cell

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.

Plasma generating apparatus for secondary battery

An electrode assembly for a secondary battery having reduced internal resistance while adhesion between a separator and an electrode is maintained and having improved electrolyte impregnation the electrode assembly including a separator having a processed area having undergone a corona discharging process and a non-processed area.

Electrode assembly including electrode and separator partially bonded to each other

The present invention relates to an electrode assembly. The electrode assembly comprises: a first separator sheet; and a first electrode sheet and a second electrode sheet, which respectively adhere to both surfaces of the first separator sheet, wherein patterned masks having different adhesion force are respectivley disposed on both the surfaces of the first separator sheet, and the first electrode sheet adheres to the mask of a first surface of both the surfaces, which has relatively high adhesion force, and the second electrode sheet adheres to the mask of a second surface having relatively low adhesion force.
