According to the Chinese national standard GB 38031–2020 , traditional experimental methods for inducing internal short circuits in lithium-ion batteries can be categorized into several forms: over-discharge, over-charge, heating, ARC test, extrusion, pinprick, mechanical impact, and simulated collision.
Internal short circuits represent a crucial intermediate stage in the process leading from abuse to thermal runaway in lithium-ion batteries. The occurrence of an internal short circuit, or the cooling of the short circuit during the rapid heat production stage, determines whether thermal runaway will be triggered.
The battery internal short circuit (ISCr) is one of the major obstacles that impede the improvement of the battery safety. Although most of the ISCr incidents only lead to the loss of battery energy and the decline of the battery performance, some of the ISCr incidents do result in the battery thermal runaway accidents (4).
