Li-ion batteries play an ever-increasing role in our daily life. Therefore, it is important to understand the potential risks involved with these devices. In this work we demonstrate thermal runaway characteristics of three types commercially available format 18650. The were deliberately driven into by overheating under controlled conditions. Cell temperatures up 850 °C and a gas release 0.27 mol measured. main components quantified gas-chromatography. safety determined their composition,...
Destructive thermal ramp experiments with commercial Li-ion batteries at different state of charge were made. Produced gases quantified and a causing chemical reaction system is proposed.

Damaged or heavily over-heated Li-ion batteries in electric vehicles can transit into a thermal runaway reaction with further heat and gas release.
The objective of functional safety is the development a system with insignificant risk potential. For that purpose, all reduction measures have to be considered early in development. This requires close collaboration different engineering disciplines order specify comprehensive concept. international standard ISO 26262 has for electrical and/or electronic (E/E) systems within road vehicles, which additionally provides basic framework consider also non-E/E measures. paper proposes (1)...
In order to understand the lithium-ion battery (LIB) failing behavior and prevent failures their consequences, different LIB safety tests, also called abuse have been developed. This paper focuses on thermal runway (TR) triggered by overtemperature, overcharge nail-penetration. It shows setup results of three TR triggers single cells in a custom-made reactor. The investigated cell is state-of-the-art automotive pouch cell. are discussed main categories: behavior, vent gas production...
Purpose This paper aims to present a fully coupled thermo-electrical finite-element battery model with an applied model-order reduction.

Li-ion batteries excel in energy density and cycle life. Unfortunately those benefits come with a price: When are mistreated high over-temperature or strong overcharge, they can transit into so-called thermal runaway (TR). During the TR, exothermic reactions increase temperature. In turn, increased temperature accelerates system destabilizes. At end of battery temperatures higher than 900°C be reached amounts burnable harmful gases released. We examined TR characteristics commercially...
