Lithium-ion batteries (LIBs) with excellent performance are widely used in portable electronics and electric vehicles (EVs), but frequent fires and explosions limit their further and more widespread applications. This review summarizes aspects of LIB safety and discusses the related issues, strategies, and testing standards.
An overview of battery safety issues. Battery accidents, disasters, defects, and poor control systems (a) lead to mechanical, thermal abuse and/or electrical abuse (b, c), which can trigger side reactions in battery materials (d).
The thermal safety of LIBs is a hot but complex topic for battery research, development, and application. Improving the safety of LIBs is very important for their sustainable development. The safety standards play a critical role in promoting the safety of LIBs. The standards should be constantly revised and evolved with the development of LIBs.
The internal failure of a LIB is caused by electrochemical system instability , . Thus, understanding the electrochemical reactions, material properties, and side reactions occurring in LIBs is fundamental in assessing battery safety. Voltage and temperature are the two factors controlling the battery reactions.
Failure of the battery is often accompanied by the release of toxic gas, fire, jet flames, and explosion hazards, which present unique exposures to workers and emergency response personnel.
