A method for sealing an anode separator of a lithium battery and its anode separator

摘要

The present invention relates to an anode separator sealing method for a lithium battery, in which a shape in which both end faces are not bent during a process of sealing a pair of anode separators with a lithium electrode sandwiched therebetween.;The present invention for solving such problems is composed of a pair of tape-type anode separators with adhesive on both ends in the width direction in the longitudinal direction and a lithium electrode plate interposed between an anode separator bonded by the adhesive, And an adhesive is injected along the longitudinal direction thereof so as to be pressed and sealed by the rollers.;By the above-described method, a pair of anode separators are sealed in the lithium electrode plate during the winding assembly operation, which is the electromotive force generating portion of the lithium battery, to prevent bending or wrinkling of both end faces of the anode separator, The anode of the lithium battery can be made, the defect rate of the lithium battery is lowered, and the reliability of the product is improved.
