摘要： A nonaqueous secondary battery 10 of the invention has an active material compound layer 14 deposed over at least one face of a collector 12 made of metal foil and is equipped with a positive electrode 11 having a portion 13 in a part of which metal is exposed. The positive electrode 11 together with the exposed-metal portion 13 faces a negative electrode 17 through an interposed separator 23, and on that part of the exposed-metal portion 13 that faces the negative electrode 17 through the interposed separator 23 there is formed a protective layer 16 made of a material whose electronic conductivity is lower than that of the metal and which moreover is non-insulative. With such nonaqueous secondary battery 10, should part of an electrode pierce the separator and contact with the other electrode, the battery will be gently discharged, thereby averting abnormal heat generation by the battery and additionally enabling the battery's abnormality to be sensed by the equipment via the fall in battery voltage. Thus, there is provided a nonaqueous secondary battery of excellent safety that can prevent abnormal heat generation due to a short circuit caused by burr, powder or the like piercing the separator.

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.
摘要翻译：锂离子二次电池的测试方法包括测量电位差＆Dgr; 在充电过程之后的外罐和负极外部端子之间，并且如果电位差＆Dgr; 是预定的规定值以上，电池被确定为无缺陷产品。该方法可以更准确地检测短路发生的电池，例如当负极外部端子和外部端子与制造装置同时接触时，与正极外部端子并测量外罐。因此，该方法可以减少由于沉积在外罐内表面上的锂金属导致的外罐腐蚀的可能性。
