Discussed is a lamination apparatus for a secondary battery. The lamination apparatus for the secondary battery includes: an electrode transfer part configured to transfer at least one or more electrodes; a separator transfer part configured to transfer at least one or more separators; a combination part configured to combine and transfer the electrodes and the separators that are to be alternately disposed; and a position correction part configured to correct a position of an uppermost electrode disposed at an uppermost side among combined electrodes and the separators to align the position of the electrode with a set position of the separator among the combined electrodes and separators.

Lamination apparatus and method for secondary battery

A system and method facilitates measuring physical properties of an electrode specimen. Accordingly, it is possible to suppress a slipping phenomenon of an electrode specimen and prevent disconnection of a gripping portion during a tensile test for the electrode specimen by forming a tape on the gripping portion of the electrode specimen and forming a grid pattern on the surface of a pressing jig.

According to the metal foil fatigue test system and metal foil fatigue test method of the present invention, the fatigue degree and lifespan of the metal foil may be easily predicted by injecting gas into the tube of a roll structure and discharging the gas to simulate charge/discharge of the electrode assembly.

System and method for fatigue testing of metal foil

The present invention relates to an ultrathin foil transferring and processing process for reducing curling and preventing folding of an ultrathin foil which may occur in the ultrathin foil transferring and processing process, and comprises: a step of coating or mounting an electrostatic-inducing material on both ends of a roll to form a charging part; a charging step of rubbing an ultrathin foil and the roll during the transferring and rolling of the ultrathin foil, to charge both ends of the ultrathin foil and the roll with positive or negative charges; and an electrostatic force applying step in which an electrostatic force is applied to both ends of the ultrathin foil simultaneously with or after the charging step and thus the curling of the ultrathin foil is reduced.

Ultrathin foil transferring and processing method capable of reducing curling of ultrathin foil and preventing folding thereof
