What are the elements of combustion under overcharge in lithium-ion-battery based devices?

Three element factors of combustion under overcharge are clarified: combustible spouted out from the battery, high temperature electrode active substance, and oxygen in the environment, respectively. The results of this work can provide some information for the safety and fire protection of lithium-ion-battery based devices. 1. Introduction

What are the parts of a lithium ion battery?

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.

Do lithium-ion battery vent gases cause explosions and fires?

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).

How does a lithium-sulfur (Li-s) battery work?

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.

Which combustible gases are generated from thermal runaway of Li-ion batteries?

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].

What are the two stages of a lithium ion battery redox reaction?

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.
