Abstract: Internal short circuit (ISC) is one of the most common causes of thermal runaway accidents in lithium-ion batteries, as a potential safety threat. It is also a common link between mechanical abuse, electrical abuse and thermal abuse. In this review, the research progress of ISC mechanism is summarized including the substitute triggering approaches and the ISC evolution process. It is proposed that the ISC detection needs to be achieved in the early and middle stages. Furthermore, a variety of ISC detection methods are summarized. Finally, the perspective of ISC is discussed.

Key words: lithium-ion battery, internal short circuit, substitute triggering approach, internal short circuit detection
