Abstract ：
Thermal runaway propagation (TRP) inside lithium iron phosphate (LFP) batteries is an important part of TRP process of the module, but it has not been known clearly. This work experimentally and numerically investigated the overheat-induced thermal runaway (TR) characteristics of 243 Ah LFP battery and the influence mechanism of heating power on TRP within the battery. A series of TR experiments under 400, 700 and 1000 W heating power were conducted. The relationship between peak jet velocity and internal average TRP velocity (vTR) was revealed for the first time. Results show safety venting and TR time decreases with increasing heating power, while the internal TRP time prolongs. Batteries with faster internal TRP velocity tend to own higher peak jet velocity. The relationship between vTR and heating power is fitted as y = 0.2421e_x/466.8843 +0.2351 based on simulation result. vTR almost decreases linearly with heating power in the range of 200-1000 W, and then enters a plateau-like descending phase. In critical TR state, the width of TR region widens as heating power increases. The acceleration of vTR induced by low heating power is mainly attributed to a better pre-heating effect in nonTR region. This work can provide important guidance for the safety design of LIB batteries.

Abstract ：
Jet fire is a typical behavior of Li-ion batteries during thermal runaway (TR), which is one of the main factors causing fire accidents in battery systems, but its dynamic dominant mechanism is still unclear. Therefore, this paper experimentally investigated the dynamic evolution of jet fire of lithium iron phosphate (LFP) and lithium nickel‑cobalt-manganate (NCM) batteries with the same capacity. A novel method based on image recognition algorithm and nonlinear fitting was proposed to reveal the dominant mechanism of jet fire and to further divide its process into stages. Besides, the effect of the state of charge (SOC)on the dynamics of jet fire was quantified. The results show the jet fire of 50%SOC NCM battery goes through five stages successively: buoyancy dominant, buoyancy-momentum co-dominant, momentum dominant, buoyancy- momentum co-dominant and buoyancy dominant, which is one more momentum dominant stage than that of 50 % SOC LFP batteries. For both 50 % SOC NCM and LFP batteries, the time ratio of buoyancy-momentum co-dominant during TR are the highest, reaching 85.1 % and 79.1 %, respectively. The outlet kinetic energy of 50%SOC LFP battery is greater than that of buoyancy work during TR process, while the proportion of time that the kinetic energy on fire is greater than that of buoyancy work in NCM battery is 47.49 %, and the time ratio of pure momentum-dominated is 5.98 %. Furthermore, the effect of gas outlet momentum on the fire increases with the increase of SOC. This paper can provide a theoretical direction for reducing the fire hazard of LIBs. © 2025

Abstract ：
Urban gas pipeline networks (UGPN) provide important support for high-quality urbanization. Therefore, it is imperative to analyze and assess the potential failures of UGPN. A novel probabilistic analysis method is proposed for assessing the safety and resilience of UGPN. Firstly, Bow-Tie analysis is used to identify faults. Then, a four-dimensional resilience assessment network is developed. Bayesian network is utilized to model the relationship between the variables, while dynamic Bayesian network is used to consider the dynamic nature of the system. The results of the study show that the proposed model can accurately estimate faults, consequences, and influence paths. Furthermore, the resilience analysis shows that monitoring the objective conditions is crucial and that the initial failure probability of the UGPN decreases from 0.03767 % to 0.01435 % when connected to a resilience network, indicating that considering resilience can effectively improve the reliability and safety of the UGPN. Two application examples are presented in the paper to validate the functionality of the proposed model. The proposed model can be used to set the state of UGPN to predict the probability of occurrence of a specific event and its consequences and to simulate the improvement trend of UGPN based on the direction of focus of future work.

Abstract ：
The occurrence of urban gas pipeline network accidents will pose a great threat to people's lives and property. To protect the lives and property of urban residents and ensure the normal operation of the city, this paper studied the influencing factors of urban gas pipeline network accidents. Firstly, the influencing factors of urban gas pipeline network accidents were summarized and the corresponding fishbone diagram was constructed following the data from the U.S. Department of Transportation Pipeline and Hazardous Materials Safety Administration. Secondly, based on the determined accident number model, the corresponding Bayesian network model was constructed to calculate the state probability and the sensitivity value. Finally, according to the relevant information of urban gas pipeline network management, combined with the numerical results of priori probability and sensitivity, an emergency linkage system based on the urban gas pipeline network was constructed. The calculation results of state probability and the sensitivity analysis indicate that corrosion is the most influential factor contributing to accidents in the urban gas pipeline network. The temperature change has the greatest influence on the occurrence of urban gas pipeline network accidents. Special attention should be paid to the prevention and management of these two aspects of the emergency linkage system. Besides, in order to verify the effectiveness of the system, this paper also uses AHP to evaluate the application of the system. This study aims to provide valuable insights for enhancing the safety management of urban gas pipeline networks, thereby elevating their safety management standards.

Abstract ：
Ceiling jet fire is a common phenomena in thermal runaway (TR) accidents of electric vehicle and energy storage power station scenarios based on lithium-ion battery, which is a potential risk of inducing large-scale fire spread in battery modules, but it is not been known clearly. This work investigates the influence of ceiling jet fire on TR propagation of lithium nickel cobalt manganese oxide (NCM) battery module by arranging a ceiling-like obstacle directly above the tested module. A series of overheat-induced TR propagation tests under different height (H) of ceiling-like obstacle are conducted to gain better understanding of the heat transfer mechanism. The heat transfer and average heating power of ceiling jet fire to adjacent cells are determined for the first time. Results indicate the TR propagation speed of the module accelerates with the decrease of H, and the TR propagation speed inside the cell is not affected by ceiling jet fire. More importantly, the heat transferred from cell experiencing TR to adjacent cells through ceiling jet fire (Q(fl)) decreases from 11087.33 J to 7872.02 J, and the ratio of Q(fl) to the total heat released in TR (Delta E-tot) declines from 4.02 % to 2.85 % as H increases from 5 to 15 cm. Finally, the change process of contact thermal resistance between adjacent cells and its relationship with heating power are revealed during TR propagation. This work provides a basic understanding of the influence mechanism of ceiling jet fire on TR propagation, which possess important guidance for the safety protection of lithium-ion battery system.
