“…The short circuit caused by nail penetration is the process of tungsten steel needle passing through the winding layer between the positive and negative poles of the cell. [32][33][34] This process cannot be characterized in AMEsim. Because the model building of the short circuit caused by nail penetration is uncertain, only the heat transfer simulation of the battery module is considered, the thermal diffusion simulation of nail penetration is equivalent to the external heating process.…”

This paper takes a certain type of large-capacity pure electric vehicle NCM li-ion power battery as the object, and analyzes and studies the process of nail penetration thermal runaway(TR). With the aid of AMEsim one-dimensional simulation software, considering the structure composition of the cell, the heat generation mechanism of each side reaction and the three heat transfer modes of thermal radiation, heat conduction and convective heat transfer between the cells, box and the environment, the thermoelectric characteristics of the battery module (six cells) are modeled. The TR behavior of the battery module during nail penetration is simulated and analyzed, and the experiment of the battery module is carried out according to Chinese new regulation GB 38031-2020. The experimental results verify the accuracy of the established model and the reliability of the simulation results, and provide technical reference for the design and development of battery thermal management such as the prediction of TR temperature and the safety of preventing thermal runaway propagation（TRP） of battery pack.

“…Blaming the causes of all these unexpected fires on an event which cannot be confirmed may omit more general mechanisms, for which preventative solutions may exist. Current studies on LIB safety mainly focused on testing a single cell or small module [5][6][7][8][9][10] to study the contribution of the chemical reactions [11][12][13][14][15][16][17] However, another important factor often omitted is that within a large-size stack of reactants, the poor heat transfer condition could also play a crucial role or trigger ignition [18]. This phenomenon has seldom been discussed for battery fires.…”

“…Usually, two models are used to investigate the performance of battery after the occurrence of internal short circuit. Electrochemical model, [18][19][20] which is based on porous electrode theory and Fick's law, is used to simulate the transportation of lithium-ion and distribution of over-potential. Wei Zhao 19 used electrochemical model to reveal the strong coupling of the cell thermal response and electrochemical behaviour.…”

Summary The safety of lithium‐ion battery provokes public concern with its wide application. Considering the electrical and thermal interplay between different parts or layers, a multilayer electro‐thermal model is developed to investigate the performance in internal short‐circuit (ISC) case before the trigger of thermal runaway. The battery internal short circuit is assumed to occur under natural convection condition and the initial temperature is 25°C. In comparison, the simulation result agrees with the experimental data. It is found that the short‐circuit performance is quite sensitive to the number of layer and short‐circuit location. The current almost triples when the number of layer increases from 2 to 32. Moreover, weakening the electrical and thermal interplay between different layers can make the battery more secure in Al‐anode ISC case. It is proposed that adding extra resistance on two adjacent metal tabs or changing tabs’ position can improve the safety. Novelty Statement Electrical and thermal interplay between different layers is considered. Adding extra resistance between different unit layers protects battery from ISC. Weakening the electrical and thermal interplay between layers is recommended.
