“…4e. The relationship between the scan rate (v) and peak current (i) is given by eqn (1), in which a and b are adjustable parameters. The value of b is obtained from the slope of the linear fitting line of log i and log v. A value of b approaching 1 indicates a capacitive-controlled behavior, while a value of b approaching 0.5 indicates a diffusion-controlled behavior.…”

“…The main reason for such safety issues is the usage of a highly flammable organic electrolyte. 1,2 Nonflammable electrolyte systems seem to be a fundamental way of avoiding such accidents. Compared with organic electrolyte battery systems, aqueous batteries offer high safety, environmental friendliness, and cost effective.…”

“…The SOA is the voltage and temperature range in which a lithium cell can operate without causing undesirable reactions leading to accelerated degradation or ultimately to TR. As can be seen in the figure, higher temperatures can trigger a series of chain reactions leading to TR [9]. However, this phenomenon can also occur in other ways, given that charging at low temperatures or overcharging can also cause lithium plating.…”

Lithium-ion batteries (LIBs) are becoming well established as a key component in the integration of renewable energies and in the development of electric vehicles. Nevertheless, they have a narrow safe operating area with regard to the voltage and temperature conditions at which these batteries can work. Outside this area, a series of chemical reactions take place that can lead to component degradation, reduced performance and even self-destruction. The phenomenon consisting of the sudden failure of an LIB, causing an abrupt temperature increase, is known as thermal runaway (TR) and is considered to be the most dangerous event that can occur in LIBs. Therefore, the safety of LIBs is one of the obstacles that this technology must overcome in order to continue to develop and become well established for uses in all types of applications. This chapter presents a detailed study of the general issues surrounding this phenomenon. The origin of the problem is identified, the causes are detailed as well as the phases prior to TR. An analysis is made of the most relevant factors influencing this phenomenon, and details are provided of detection, prevention and mitigation measures that could either prevent the TR or reduce the consequences.

“…As a BTMS must prevent the battery pack (BP) from reaching temperatures outside the optimal working range (15-40 • C for Li-ion cells [21]), preserving its performance, safety, and state of health (SOH), PCMs are increasingly studied in this field, too. There are several reasons for a Li-ion battery (LIB) fault, such as thermal, mechanical, or electrical abuses [22], and the strategies to reduce potential accidents can be grouped into active and passive safety methods. An active strategy mainly relies on heat transfer increase to remove excess heat (forced-air or liquid BTMSs); a passive method works on exploiting TESSs, without an external energy supply, and modifying the physics of the materials involved (PCMs thermal management).…”

In this work, a commercial paraffin PCM (RT35) characterized by a change range of the solid-liquid phase transition temperature Ts−l = 29–36 ∘C and the low thermal conductivity λSL = 0.2 W/m K is experimentally tested by submitting it to thermal charging/discharging cycles. The paraffin is contained in a case with a rectangular base and heated from the top due to electrical resistance. The aim of this research is to show the benefits that a 95% porous copper metal foam (pore density PD=20PPI) can bring to a PCM-based thermal storage system by simply loading it, due to the consequent increase in the effective thermal conductivity of the medium (λLOAD = 7.03 W/m K). The experimental results highlight the positive effects of the copper foam presence, such as the heat conduction improvement throughout the system, and a significant reduction in time for the complete melting of the PCM. In addition, the experimental data highlight that in the copper-foam-loaded PCM the maximum temperature reached during the heating process is lower than 20K with respect to the test with pure PCM, imposing the same heat flux on the top (P=3.5 W/m2).
