A battery short circuit is a condition where the electrical current in the battery bypasses the normal flow of electrons through the circuit. This can happen if the positive and negative terminals of the battery are accidentally touched together, or if a wire that is connected to the battery becomes frayed or broken. When a short circuit occurs, it can cause damage to the

A battery''s maximum short circuit current depends on various factors, including the battery''s chemistry, size, and internal resistance. The larger the battery, the higher its short circuit current. For example, a car battery can have a short circuit current of several hundred amps, while a small button cell battery may only have a few milliamps.

Internal short circuit (ISCr) is one of the major reasons for lithium-ion battery thermal runaway. A new phenomenon, named as the Fusing Phenomenon, is observed during the ISCr experiments. During the Fusing Phenomenon, the ISCr current path will melt down due to the Joule heat of the short current and the ISCr process will be interrupted.
