| titleOfInvention | Secondary battery inspection method |
| abstract | PROBLEM TO BE SOLVED: To provide a method for inspecting a secondary battery capable of accurately detecting the presence or absence of a micro short circuit in the secondary battery. A method of inspecting a secondary battery according to the present invention includes a step of preparing a secondary battery in which a power generating element including a positive electrode and a negative electrode and a battery case are insulated by an insulating film. Charging the secondary battery, measuring the first voltage, which is the potential difference between the negative electrode and the battery case in a state where the secondary battery is compressed from the outside of the battery case, and compressing the secondary battery is predetermined. To maintain the compressed state so that the maintained time is maintained, and to measure the second voltage, which is the potential difference between the negative electrode and the battery case, of the secondary battery whose compressed time is equal to or longer than the maintained time. And a step of determining that the secondary battery is defective when at least one of the first voltage and the second voltage is smaller than a predetermined threshold voltage.
