摘要： Methods for evaluating battery safety under internal short-circuit conditions are improved to eliminate variations in evaluation results and accurately evaluate battery safety under internal short-circuit conditions. An internal short-circuit is caused in a battery by using an internal short-circuit causing method in which battery information obtained upon the occurrence of an internal short-circuit hardly changes with the structure of the battery. At this time, the battery information is detected to accurately evaluate the safety of the battery upon the internal short-circuit and identify the safety level.

摘要： In the non-aqueous electrolyte secondary battery of the present invention, the separator includes a heat-resistant resin having chlorine atoms as an end group and the positive electrode active material includes a lithium-containing complex oxide containing aluminum atoms in its composition. Even if the chlorine atoms are liberated into the non-aqueous electrolyte, aluminum contained in the positive electrode active material is selectively leached into the non-aqueous electrolyte, thereby suppressing the leaching of other component elements. Consequently, there can be obtained a non-aqueous electrolyte secondary battery excellent in safety and high temperature storage characteristics.

摘要： The invention provides a method for evaluating the safety of a battery under an internal short-circuit condition. The battery includes: an electrode group including a positive electrode, a negative electrode, and an insulating layer for electrically insulating the electrodes, which are wound or laminated; an electrolyte; a housing for housing the electrode group and the electrolyte; and a current-collecting terminal for electrically connecting the electrode group and the housing. The method of the invention includes: placing a foreign object at a location inside the electrode group of the battery where the positive electrode and the negative electrode face each other; and pressing the location by the pressure applied by a pressing tool to locally crush the insulating layer between the positive and negative electrodes, thereby causing an internal short-circuit. The contact area of the electrode group and the pressing tool during the pressing is larger than the area of a rectangle circumscribed about the foreign object. A short-circuit test is conducted at a given location inside the battery to comprehensively evaluate the safety of the battery under an internal short-circuit condition.
