An unexpected explosion of battery pack was occurred during the experiment. The thermo-electric behavior of the battery pack just before the explosion was studied. The primary cause of explosion and explosion handling techniques are also explored. 3.1. Single cell experimental setup
The explosion of one cell in the battery results in increase in temperature of adjacent cell, which result in the explosions in succession. The repeated use of fire extinguisher helped to control the fire. The explosion of cells results in release of poisonous gas, which is vented by opening all the windows and using fan and hand blower.
Aluminum-ion batteries function as the electrochemical disposition and dissolution of aluminum at anode, and the intercalation/de-intercalation of chloraluminite anions in the graphite cathode.
The rise in temperature of a few cells in the battery pack, leading to the explosion event, can be attributed to the initiation of side reactions between lithium metal and water molecules within the cells. This is due to the presence of moisture trapped in the cell from earlier water-cooling experiments.
Ogunfuye et al. [37, 38] numerically studied the explosion pressure of various Li-ion batteries, and results suggested that the explosion pressure is sensitive to the BVG's compositions, and they incorporated the Cantera software into the explosion vent analyzer platform to predict the both laminar flame speed and peak pressure of BVG.
The explosion behavior of Li-ion battery is studied in lab scale model battery pack with 32 cell and with single cell experiment. The study can be further extended with explosion and fire hazards of an actual battery pack within an EV.
