The results of this work can provide some information for the safety and fire protection of lithium-ion-battery based devices. 1. Introduction
LIBs are mainly composed of four parts: cathode, anode, electrolyte and separator. When the battery is subjected to thermal, electrical and mechanical abuse, a series of side reactions will occur inside the battery and heat will be released.
The thermal runaway and catastrophic failures of lithium-ion batteries that release combustible gases, which, when mixed with air, can lead to explosions and fires. In this paper, experiments were conducted to determine the laminar flame speed and explosion pressure of the battery vent gases (BVGs).
The operation of a lithium-sulfur (Li-S) battery involves the transport of Li⁺ ions and soluble sulfides mostly in the form of solvated ions. Key challenges in the development of Li-S battery technology are the diffusion of Li⁺ in micropores filled with sulfur and eliminating the “shuttling” of polysulfides.
According to the literature survey, the leading combustible gases generated from the thermal runaway of various Li-ion batteries were H 2, CO, CH 4, and C 2 H 4, and the contents of CH 4 and C 2 H 4 are almost the same while the mole fraction of H 2 and CO changes with the SOC and anode material [18, 19, 47, 48].
Vent gas from LIBs is divided into two stages, the first stage is dominated by low boiling point electrolyte, and the second stage is characterized by the generation of large amounts of gas due to redox reactions between the component materials of the battery.
