<p>A sheet type cell in which a storage layer is sandwiched by layers of a positive electrode and a negative electrode is evaluated. The present invention is characterized in that an electrode probe is brought into contact with a measurement part on an outer surface of at least one of the positive electrode and the negative electrode, and quantity of electricity is measured at the measurement part, so as to evaluate the sheet type cell. For example, a charge source and a voltage meter are connected to the electrode probe, and a charge characteristic that changes the sheet type cell from a non-charged state to a fully charged state is detected from a change in a measurement voltage of the voltage meter, so as to make an evaluation. Further, for example, a discharge source and the voltage meter are connected to the electrode probe, and a discharge characteristic that changes the sheet type cell from the fully charged state to the non-charged state is detected from the change in the measurement voltage of the voltage meter, so as to make an evaluation. Furthermore, for example, the charge source and the voltage meter are connected to the electrode probe, and the measurement voltage of the voltage meter is detected when the sheet type cell is in the fully charged state, so as to make an evaluation.</p> |
