This study analyzes thermal runaway (TR) characteristics via experiments conducted on lithium-ion batteries. To generate the TR of lithium-ion batteries, overcharge was applied as an electrical abuse condition. The TR experiment was conducted in a chamber with the dimensions of 1.5 × 1.5 × 1.5 m by classifying the capacity of a pouch-type lithium-ion battery and cathode material employed. The experimental results demonstrated that the lithium-ion battery before TR exhibited repetitive voltage and temperature characteristics, and that TR could be detected in advance based on these characteristics. TR occurred after the cell surface temperature of the lithium ion battery was maintained at approximately 100 ℃ for a certain duration. The voltage of the lithium-ion battery gradually increased before TR; however, the voltage decreased after the inflection point (Vmax) was crossed. Then, the voltage increased sharply after decreasing for a certain duration and was higher than the voltage increase rate (V/min) observed before the inflection point (Vmax) was attained.

The lithium-ion battery industry has been developing rapidly, with energy density and capacity constantly improving. However, the ensuing safety accidents of lithium-ion power batteries have seriously threatened the personal safety of passengers. Therefore, more and more attention has been paid to the thermal safety research of lithium-ion batteries, such as thermal runaway (TR) mechanism analysis and prevention methods, etc. In this paper, the nickel-rich 18650 lithium-ion batteries with Li[Ni0.8Co0.1Mn0.1]O2 cathode in different states of charge (SOC) are taken to investigate the TR characteristics using an extended volume plus acceleration calorimeter (EV+-ARC). In order to evaluate the TR characteristics, some characteristic parameters such as battery voltage, surface temperature, temperature rise rate, etc. are selected from the experiment to analyze the influence of SOC on the critical state of TR. It can be seen from the experiment results that the maximum temperature of the battery surface decreases with the decrease of SOC, while the self-generated heat temperature and TR trigger temperature increases with the decrease of SOC.

The high capacity and voltage properties demonstrated by lithium-ion batteries render them as the preferred energy carrier in portable electronic devices. The application of the lithium-ion batteries which previously circulating and contained around small-scale electronics is now expanding into large scale emerging markets such as electromobility and stationary energy storage. Therefore, the understanding of the risk involved is imperative. Thermal runaway is the most common failure mode of lithium-ion battery which may lead to safety incidents. Transport process of immense amounts of heat released during thermal runaway of lithium-ion battery to neighboring batteries in a module can lead to cascade failure of the whole energy storage system. In this work, a model is developed to predict the propagation of lithium-ion battery in a module for large scale applications. For this purpose, kinetic of material thermal decomposition is combined with heat transfer modelling. The simulation is built based on chemical kinetics at component level of a singular cell and energy balance that accounts for conductive and convective heat transfer.
