If a Li-ion cell fails and the electrolyte leaks out into air, a flammable premixed gas cloud can be formed. The electrolyte combustion energy is 65–70% of the total energy content of the cell. The main objective of this study is to determine the laminar burning velocity and the Markstein length for dimethyl carbonate and propane in a 20-liter explosion sphere with initial conditions at 100 kPa and 300 K. Five different stretch extrapolation models for the laminar burning velocity give practically the same result. The experimental results agree well with the previously published data and are slightly lower than the theoretical predictions. The laminar burning velocity for dimethyl carbonate is measured close to the saturation point under the initial conditions, which has not been previously reported.

锂离子电解质溶剂形成碳酸二甲酯-空气混合物的层流燃烧速度

如果锂离子电池发生故障并且电解液泄漏到空气中，则会形成易燃的预混气体云。电解液燃烧能量占电池总能量的 65-70%。本研究的主要目的是确定初始条件为 100 kPa 和 300 K 的 20 升爆炸球中碳酸二甲酯和丙烷的层流燃烧速度和马克斯坦长度。 层流燃烧速度的五种不同拉伸外推模型给出几乎相同的结果。实验结果与先前公布的数据吻合良好，略低于理论预测。碳酸二甲酯的层流燃烧速度是在初始条件下接近饱和点测量的，这在以前没有报道过。
