Experimental study on the thermal runaway and fire behavior of LiNi0.8Co0.1Mn0.1O2 battery in open and confined spaces

Pengjie Liu et al.

Summary: This study focuses on the thermal runaway and fire behavior of large-scale lithium-ion batteries (LIBs), especially for high energy density cells. Experimental tests were conducted under different conditions to evaluate the fire behavior of LIBs, and the effects of state of charge and confined cabinets were analyzed. The results indicate that the asphyxiant gases have a more significant impact on human toxicity compared to irritant gases. The minimum fresh air renewal rate required was also calculated to guide ventilation management and firefighting measures.

Effect of lithium salts LiPF6 and LiBF4 on combustion properties of electrolyte with EC/PC/EMC under different pressures

Shibiao Qiao et al.

Summary: This study investigated the combustion properties of ethylene carbonate/propylene carbonate/ethyl methyl carbonate (EC/PC/EMC) with LiPF6 or LiPF4 under various environmental pressures. The effects of lithium salts and pressure on flame temperature, mass loss rate (MLR) and heat release rate (HRR) were analyzed to assess the thermal hazard. The results showed that as the ambient pressure decreased, the peak HRR (pHRR) and total heat release (THR) decreased, while the combustion duration increased significantly. The mean value of MLR in the steady combustion stage had an exponential relationship with the external pressure. The error of HRR obtained by oxygen consumption (OC) calorimetry and stoichiometric thermochemistry (TC) theory was about 15%.

An experimental study on thermal runaway and fire behavior of large-format LiNi0.8Co0.1Mn0.1O2 pouch power cell

Kaiyu Zou et al.

Summary: This study investigates the thermal runaway and fire behaviors of 78 Ah LiNi0.8Co0.1Mn0.1O2 pouch batteries under different incident heat fluxes. The results show that the heat released from the cathode can be ignored, and there is a correlation between the time to ignition and the incident heat flux. Additionally, a flame centerline temperature distribution model is established, providing insights for thermal protection and evaluation.

Combustion characteristics of lithium-iron-phosphate batteries with different combustion states

Q. I. Peiyan et al.

Summary: By conducting combustion and smouldering experiments on a 60-Ah steel-shell battery using a lithium-ion battery combustion experiment platform, it was found that battery combustion poses a high thermal hazard with total heat release approximately 17 times that of the smouldering process. The smouldering process, on the other hand, showed a high gas hazard.

Experimental study on thermal runaway behaviors of 18650 li-ion battery under enclosed and ventilated conditions

Junchao Zhao et al.

Summary: The study found that under enclosed conditions, the concentration of flammable gases increased with the state of charge (SOC), leading to an increased risk of gas explosion. However, under ventilated conditions, the risk of rupture decreased. External pressure was identified as a key factor impacting the case rupture.

Modeling cell venting and gas-phase reactions in 18650 lithium ion batteries during thermal runaway

Jinyong Kim et al.

Summary: A numerical model was developed to study the cell venting, internal pressure, and gas-phase dynamics behavior of 18650 Li-ion cells undergoing thermal runaway. The study found that the cell response is mainly dominated by the thermal runaway reactions, with cells at higher states-of-charge producing more heat and gas during venting events, increasing the risk of side-wall breaching.

A 2D CFD model investigation of the impact of obstacles and turbulence model on methane flame propagation

T. Nguyen et al.

Summary: Studying the effects of obstacle shape, turbulence model, and spark location on flame propagation and turbulence has provided a more complete understanding of the flame and fluid dynamics interaction. Results showed that square obstacles caused faster flame propagation compared to hexagons and circles. Variation of spark location by as small as 10 % of the obstacle diameter can result in a difference in flame propagation.
