摘要： The invention provides an evaluation method and an evaluation apparatus with which it is possible to know the safety level of batteries when an internal short circuit occurs through a chemical process, and a battery whose safety level has been determined with the evaluation method and the evaluation apparatus. A battery that has been charged to a predetermined voltage and into which conductive foreign matter has been incorporated is immersed in an electrolyte. The time at which the battery started to dissolve in the electrolyte is determined. Occurrence of an internal short circuit in the battery is detected based on a battery voltage. A time required for occurrence of short circuit is computed based on the above-described dissolution start time and the time of occurrence of the internal short circuit, and then output.

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.
