Abstract
Disclosed is a method for measuring cell performance. The method for manufacturing performance of a unit cell, in which a first electrode provided with a first electrode tab, a separator, and a second electrode provided with a second electrode tab are alternately laminated to be bonded to each other, comprises an additional lamination step of further laminating counter electrodes, each of which has the same polarity as that of the second electrode and is provided with a third electrode tab, on sides facing the first electrode at the outermost sides of the unit cell with the separator therebetween, and an outer interface analysis step of measuring a different in performance between the first electrode and each of the counter electrodes by electrically connecting the first electrode tab disposed on the first electrode to the third electrode tab disposed on the counter electrode.
