METHOD FOR SEALING ELECTRODE ASSEMBLY AND SEALING DEVICE THEREFOR

A method for sealing an electrode assembly, which includes a plurality of electrodes stacked alternately with a separator therebetween, according to an embodiment of the present invention may include seating the electrode assembly on a nest, and sealing the electrode assembly by spraying hot air toward a corner portion of the electrode assembly. [0002] A device for sealing an electrode assembly, which includes a plurality of electrodes stacked alternately with a separator therebetween, according to another embodiment of the present invention may include a nest that supports the electrode assembly, and a hot air blower that sprays hot air toward a corner portion of the electrode assembly to seal the corner portion in a non-contact state. [0003] According to embodiments of the present invention, the sealing may be performed in a non-contact method to minimize an impact or damage on a portion other than an object to be sealed or a sealing region, which may be caused by physical contact during the sealing. Moreover, conditions for performing the sealing may be controlled according to situations to adaptively secure the uniform and stable sealing quality.
