FOREIGN MATTER INSPECTION METHOD OF ELECTRODE ASSEMBLY FOR ELECTROCHEMICAL ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a foreign matter inspection method of electrode assembly for electrochemical element applicable to a large size electrode assembly for electrochemical element.SOLUTION: The foreign matter inspection method of electrode assembly for electrochemical element for measuring a current which flows when a voltage is applied to the electrodes of the electrode assembly for electrochemical element which is formed by laminating the electrodes and the separators. The voltage applied to the electrodes is 0.1-2.0 V.SELECTED DRAWING: Figure 1
