In this review, we analyzed the main causes of the safety risks of LIBs and examined the inherent electrochemical mechanisms of LIBs. We also summarized the main factors that affect the safety of on-board LIBs, including battery materials, design, abuse conditions, and battery status.
Thus, to reduce the thermal hazard of Lithium-ion battery, adequate measures have been reviewed, such as usage of thermally protective separators, safety devices, flame retardants, passive cooling devices, and fire suppressants.
Specific risk control measures should be determined through site, task and activity risk assessments, with the handling of and work on batteries clearly changing the risk profile. Considerations include: Segregation of charging and any areas where work on or handling of lithium-ion batteries is undertaken.
However, the thermal runaway problems of LIBs largely limit the wider promotion of EVs. To provide background and insight for the improvement of battery safety, the general working mechanism of LIBs is described in this review, followed by a discussion of the thermal runaway process, including the trigger conditions and material factors.
Based on these factors, we discussed the methods used to improve battery safety from two perspectives: material and state estimation. Material improvements include material modification, novel material development, and functional additives, while state estimation include SOH and SOC.
Therefore, the layered material and passivation film are the two cornerstones for the safety of the battery anode material. The adverse reaction between lithium and the electrolyte and the generation of lithium dendrites are the main safety risks.
