Defining the State of Safety (SOS) for Lithium-Ion Batteries in EVs: A Discussion

DOI:https://doi.org/10.2172/3013213· OSTI ID:3013213
The demand for lithium-ion batteries (LIBs) is skyrocketing, driven by the rapid growth of electric vehicles (EVs) and grid energy storage. However, current LIBs rely on flammable electrolytes, making them susceptible to thermal runaway and fires. Despite ongoing research and development efforts to enhance safety, fire incidents in EVs and energy storage systems persist. As LIB deployment increases, so too does the risk of fires. Therefore, it's crucial to define a "State of Safety" for LIBs - encompassing both operational safety and post-incident safety, such as after a car accident. This concept can help stakeholder and first responders to effectively manage LIB fire risks.
