“…The possible hot spots generated by an internal short circuit can ignite thermal runaways leading to a fire or explosion of the batteries [8,13,14]. However, some of these problems would be solved if these technologies were subject to better understanding of the spatiotemporal thermal mapping of the batteries under different and real-time operating conditions, improving the thermal management of all battery systems.…”

In this paper, a network of 37 fiber Bragg grating (FBG) sensors is proposed for real-time, in situ, and operando multipoint monitoring of the surface temperature distribution on a pack of three prismatic lithium polymer batteries (LiPBs). Using the network, a spatial and temporal thermal mapping of all pack interfaces was performed. In each interface, nine strategic locations were monitored by considering a three-by-three matrix, corresponding to the LiPBs top, middle and bottom zones. The batteries were subjected to charge and discharge cycles, where the charge was carried out at 1.0 C, whereas the discharge rates were 0.7 C and 1.4 C. The results show that in general, a thermal gradient is recognized from the top to the bottom, but is less prominent in the end-of-charge steps. The results also indicate the presence of hot spots between two of the three batteries, which were located near the positive tab collector. This occurs due to the higher current density of the lithium ions in this area. The presented FBG sensing network can be used to improve the thermal management of batteries by performing a spatiotemporal thermal mapping, as well as by identifying the zones which are more conducive to the possibility of the existence of hot spots, thereby preventing severe consequences such as thermal runaway and promoting their safety. To our knowledge, this is the first time that a spatial and temporal thermal mapping is reported for this specific application using a network of FBG sensors.

“…[41][42] Nonetheless, medical staff should always don appropriate personal protective equipment because the other components of lithium ion batteries may cause skin or eye irritation. In addition to flame burns, a recent case report by Nicoll et al 5 discusses a patient who presented with features of both flame and alkali burns. The authors verified the alkali component of the burn through skin pH testing.…”

“…Explosions of lithium ion batteries have been well documented in relation to their use in laptop computers and cellular phones. [3][4][5] The electrolyte liquid within the lithium ion battery cells is at risk for overheating, thus building pressure that may exceed the capacity of the battery casing. This "thermal runway" can ultimately result in cell rupture or combustion.…”

Electronic cigarettes, often referred to as e-cigarettes, have established a considerable market in North America over the last decade. In parallel to this trend, there has been a surge of e-cigarette battery explosions reported in the general media. Given the growing number of such events, acute care physicians should recognize the associated risks and injury patterns and initiate appropriate treatment. This report presents two cases of burn injuries from e-cigarette battery explosions requiring surgical management. The accompanying comprehensive literature review highlights the emerging importance of e-cigarettes as an aetiology of burn injury.

“…Such damage can trigger a hazardous short circuit, driving a "thermal runaway" reaction and battery fire [7]. Reports of these events include a significant re-call of rechargeable laptop batteries due to fires [8] and a small number of published case reports of battery fire injuries relating to mobile phones [9][10][11][12][13].…”
