In this paper, a novel experimental setup to quantify the particle deposition during a lithium-ion battery thermal runaway (TR) is proposed. The setup integrates a single prismatic battery cell into an environment representing similar conditions as found for battery modules in battery packs of electric vehicles. In total, 86 weighing plates, positioned within the flow path of the vented gas and particles, can be individually removed from the setup in order to determine the spatial mass distribution of the deposited particles. Two proof-of-concept experiments with different distances between cell vent and module cover are performed. The particle deposition on the weighing plates as well as the particle size distribution of the deposited particles are found to be dependent on the distance between cell vent and cover. In addition, the specific heat capacity of the deposited particles as well as the jelly roll remains are analyzed. Its temperature dependency is found to be comparable for both ejected particles and jelly roll remains. The results of this study help researches and engineers to gain further insights into the particle ejection process during TR. By implementing certain suggested improvements, the proposed experimental setup may be used in the future to provide necessary data for simulation model validation. Therefore, this study contributes to the improvement of battery pack design and safety.

Phosphorus is regarded as a promising material for high‐performance lithium‐ion batteries (LIBs) due to its high theoretical capacity, appropriate lithiation potential, and low lithium‐ion diffusion barrier. Phosphorus/carbon composites (PC) are engineered to serve as high‐capacity high‐rate anodes; the interaction between phosphorus and carbon, long‐term capacity retention, and safety problems are important issues that must be well addressed simultaneously. Herein, an in situ polymerization approach to fabricate a poly‐melamine‐hybridized (pMA) phosphorus/carbon composite (pMA‐PC) is employed. The pMA hybridization enhances the density and electrical conductivity of the PC, improves the structural integrity, and facilitates stable electron transfer within the pMA‐PC composite. Moreover, the pMA‐PC composite exhibits efficient adsorption of lithium polysulfides, enabling stable transport of Li+ ions. Therefore, the pMA‐PC anode demonstrates a high specific charging capacity of 1,381 mAh g−1 at 10 A g−1, and a great capacity retention of 86.7% at 1 A g−1 over 500 cycles. The synergistic effect of phosphorus and nitrogen further confers excellent flame retardant properties to the pMA‐PC anode, including self‐extinguishing in 2.5 s, and a much lower combustion temperature than PC. The enhanced capacity and safety performance of pMA‐PC show potential in future high‐capacity and high‐rate LIBs.
