Abstract
(EN)
The present invention relates to a cell performance measuring method. The cell performance measuring method according to the present invention corresponds to a method for measuring a performance of a unit cell manufactured by alternately laminating and bonding a first electrode including a first electrode tap, a separator, and a second electrode including a second electrode tap, and comprises: an additional laminating step of further laminating a facing electrode on a side, which faces the first electrode, of the outermost periphery of the unit cell with the separator interposed therebetween, the facing electrode having the same polarity as that of the second electrode and including a third electrode tap; and an outer interface analysis step of electrically connecting the first electrode tap included in the first electrode and the third electrode tap included in the facing electrode and measuring an interface performance difference between the first electrode and the facing electrode.
