The temperature–time curves for the battery are generally similar, with high SOC batteries having higher energy, resulting in higher peak temperatures after the thermal runaway.
Larger energy storage leads to higher risk of thermal runaway, due to its difficulty in cooling [123]. 3D model is able to capture the main characteristic of TRP on large-format LIB [124]. Compared with the lumped model, 3D model can present the temperature distribution in a sound way [ 125 ].

Lithium-ion batteries (LIBs) are becoming the preferred solution for a new generation of electric vehicles and static energy storage equipment. In the process of storage and transportation of LIBs, the accumulation of large volumes of batteries is prone to self-ignite, leading to thermal runaway, resulting in serious consequences and losses.
Quantitative risk assessments have shown how current safeguards and best practices can significantly reduce the likelihoods of resulting battery fires and other undesired events to levels acceptable to operator. The scope of the paper will include storage, transportation, and operation of the battery storage sites.
Lithium-ion Battery Energy Storage Systems (BESS) have been widely adopted in energy systems due to their many advantages. However, the high energy density and thermal stability issues associated with lithium-ion batteries have led to a rise in BESS-related safety incidents, which often bring about severe casualties and property losses.
In electrochemical energy storage systems, large-format LiFePO4 (LFP) batteries are usually formed the battery pack under preload force. However, the preload force effect on the safety of the

In batteries, thermal runaway describes a chain reaction in which a damaged battery begins to release energy in the form of heat, leading to further damage and a feedback loop that results in rapid heating. Left unchecked, the heat generated can cause a fire. The only way to stop thermal runaway is rapid cooling of the affected cell (s
