Short circuit inspection method for battery and method of manufacturing batteries

摘要

In a method of inspecting batteries for short circuit failures, an electrode plate group 1 composed of positive and negative electrode plates 2, 3 with intervening separators 4 interposed therebetween is set on a pressing station 7, where it is compressed during short-circuiting inspection is performed, for simulating a state wherein separators are compressed by swelling electrode plates 2, 3 during charging and discharging of battery.
