A lithium-ion battery is a type of rechargeable battery commonly used as a power source in portable electronics and electric vehicles. Safety analysis related to lithium-ion batteries is used for accidents in recent years and the desire to be used in the transportation sector. Advances in scientific knowledge related to the study of types of battery failure and an extreme technological breakthrough in computer science now enable effective analysis of the resistance mechanisms that contribute to the design of the latest batteries. The continuation of this work provides an overview of safety analyses and simulations performed to illustrate failure mechanisms, highlighting the hazards of ignitions/explosions and associated accidental events. The progress of simulation models, model-related physics, and the strong interdependence between the simulations and the demonstration of safety are discussed. Current limitations and opportunities have also been brought into focus. In terms of market trends, safety is still seen as one of the main constraints to find acceptable trade-offs in the overall efficiency and cost of lithium-ion batteries in the future. The assumptions were confirmed by independent penetration tests of batteries, which showed the vulnerability of the batteries and the potential fire risk.
