Summary This paper summarizes the mitigation strategies for the thermal runaway of lithium-ion batteries. The mitigation strategies function at the material level, cell level, and system level. A time-sequence map with states and flows that describe the evolution of the physical and/or chemical processes has been proposed to interpret the mechanisms, both at the cell level and at the system level. At the cell level, the time-sequence map helps clarify the relationship between thermal runaway and fire. At the system level, the time-sequence map depicts the relationship between the expected thermal runaway propagation and the undesired fire pathway. Mitigation strategies are fulfilled by cutting off a specific transformation flow between the states in the time sequence map. The abuse conditions that may trigger thermal runaway are also summarized for the complete protection of lithium-ion batteries. This perspective provides directions for guaranteeing the safety of lithium-ion batteries for electrical energy storage applications in the future.

Unlocking the self-supported thermal runaway of high-energy lithium-ion batteries (2021, neutral): “Once the triggering reactions are started, the tremendous heat generated by the triggering reactions would immediately initiate the major heat-generating reactions between the battery components, leading to uncontrollable rise in battery temperature 15, 16 .”
A review of the internal short circuit mechanism in lithium‐ion batteries: Inducement, detection and prevention (2021, background): “These issues are primarily reflected in the thermal runaway (TR) caused by the chain exothermic reaction in batteries.(1,15) Some typical TR accidents of LIBs have been listed in Table 1 during the past 10 years, although the inducements are different.”
