| Zusammenfassung | Despite their excellent properties as electrochemical energy storage devices, lithium-ion-batteries (LIBs) are potentially hazardous due to the possibility of thermal runaway (TR). TR can be particularly dangerous in explosive atmospheres such as those found in mines. To mitigate the consequences, flameproof enclosures according to IEC 60079-1 can be used to house the LIBs. In order to quantify the material stress, TR experiments were performed by overheating a LIB (18650 format, NMC-811) in a flameproof enclosure, recording the explosion pressure and temperature. The parameters of internal surface and gas mixture (propane, hydrogen) were modified. By varying the volume of the enclosure, a direct proportionality between volume and explosion pressure was observed. This was due to the increase in internal surface area accompanied by a reduction in volume, resulting in improved heat transfer. In particular, the increase in surface area resulting from the use of expanded metal grids as internal pressure relief confirmed the surface dependance with a pressure reduction of 49 %. Furthermore, a linear relationship was established between the system energy, consisting of the energy released by the cell and the chemical energy of the gas atmosphere, and the pressure energy after TR. |
