Titolo della tesi: Lithium-Ions Battery Fires: Methodologies for the Extinction and the Remediation of Contaminated Sites
Abstract
The European Green Deal, declared with the Paris Agreement of December 12th 2015, is on track to meet its carbon emissions reduction target by 2050. This will be achieved by a huge increase in electric mobility in the next few years, which will partly replace road mobility from internal combustion engines, fed by carbon liquid fuels, with electric vehicles. The future is looking bright as we move towards electric vehicles, with cutting-edge technology like high energy and high-power Lithium-ions batteries (LIBs) making them comparable and competitive with other mobility technologies. As we embrace this new era of electric mobility, we're also delving into exciting new areas like energy production, storage and distribution, and safety. The central objective of this thesis is to address the safety of lithium-ion batteries (LIBs) by examining various methodologies for the extinction of fire and the remediation of contaminated sites in the aftermath of a fire.
The work is divided into three main sections:
SECTION 1: The results of experimental tests on the thermal behavior of LIBs are reported in order to introduce the potential hazard attached with this technology.
SECTION 2: A series of experimental tests were conducted on the LIBs fire extinction, with the objective of identifying the most efficient extinguishing agent. In addition, a phenomenological study was undertaken to investigate and comprehend the actions of each agent.
SECTION 3: The environmental impact caused by solid, liquid and gaseous emissions generated during the fire and the extinction of LIBs is evaluated, and a study on the possible remediation techniques for contaminated soils is proposed.
Following the PhD project and experiences, a series of events came to light, which have the potential to mark and highlight all the important steps related to LIBs accidents and safety. The extinguishing agent that have been determined to be the most efficacious, as determined by experimental testing, will be the subject of this PhD thesis.
