摘要:
A method for detecting soft shorts in an electrode assembly includes the following steps. First, the electrode assembly having at least one anode and at least one cathode is provided, a separator having an open porosity being inserted between each anode and cathode. Subsequently, the impedance of the electrode assembly is measured and the measured impedance is compared with a reference value. A soft short is detected if the measured impedance deviates from the reference value. The electrode assembly is not laminated, and the impedance is measured prior to the introduction of electrolyte and the installation of the electrode assembly in a galvanic cell are provided. A test stand for the method and a production line using the test stand are disclosed.
