As the increasing demand and widening range of application, lithium-ion battery (LIB) is becoming indispensable equipment in daily life. However, accidents related to LIB-powered facilities have been reported continually. In this paper, we studied the LIB risk analysis techniques and battery-related emergency response. Fault tree (FT), failure mode and effects analysis (FMEA), Bayesian network (BN) and systems-theoretic process analysis (STPA) are introduced. And the applications of abovementioned techniques are reviewed. Advantages and disadvantages of these techniques are discussed, with suggestions for the method selection. Further, the discussion of battery fire-extinguishing procedure emphasizes standardization of emergency response and battery manufacturing. This work aims to inspect LIB risk in a systematic perspective, which can be instructive to battery system safety from design stage to emergency disposal.

Keywords: Lithium-ion battery, Risk analysis, Fault tree, Failure mode and effects analysis, Bayesian network, Systems-theoretic process analysis.
