摘要： The test method for a lithium-ion secondary battery comprises a measuring potential difference Δ between an outer can and a negative electrode external terminal after a charging process, and if the potential difference Δ is a predetermined prescribed value or greater, the battery is determined as a non-defective product. This method can more accurately detect a battery in which a short circuit occurs temporarily, for example, when the negative electrode external terminal and the outer can come into contact simultaneously with a manufacturing apparatus than the case when a potential difference between the positive electrode external terminal and the outer can is measured. Thus the method can reduce the possibility of corrosion of the outer can due to lithium metal deposited on the inner surface of the outer can.
