“…Therefore, based on our previous research on the generation reasons (Li et al, 2019a), eruption characteristics (Wang et al, 2019a;Zhang et al, 2020), component identification , ignition sources , and flammability analyses (Li et al, 2019b) of CEGs, we summarize the CEG component identification results of 29 thermal runaway tests conducted in an inert atmosphere, as presented in the literature Somandepalli et al, 2014;Golubkov et al, 2014Golubkov et al, , 2015Lammer et al, 2017;Essl et al, 2020). According to the results, a time sequence diagram of CEG generation is drawn, and the three fire boundaries of CEGs, including c CEG, ignition , c O2, ignition , and T ignition , are analyzed on the basis of thermal ignition theory.…”

“…Therefore, the ignition process of a cell belongs to the self-accelerating reaction mode, which is controlled by the reaction activity, as shown in Figure 9. The CEG ignition mode can be controlled by changing the CEG temperature and ignition sources, i.e., reactivity-controlled self-accelerated chemical reaction mode (Li et al, 2019a).…”

“…As the temperature of the battery rises to above ≈80 °C, the exothermic chemical reaction rate inside the batteries increases and further heats up the cell, resulting in a positive feedback cycle. [ 9 , 10 , 11 ] The continuously rising temperatures may result in fires and explosions, especially for large battery packs. [ 11 ] The TR process can be divided into three stages: [ 9 , 10 , 11 ] the onset of overheating (stage 1), heat accumulation and gas release (stage 2), and combustion and explosion (stage 3).…”

Vigorous development of electric vehicles is one way to achieve global carbon reduction goals. However, fires caused by thermal runaway of the power battery has seriously hindered large-scale development. Adding thermal runaway retardants (TRRs) to electrolytes is an effective way to improve battery safety, but it often reduces electrochemical performance. Therefore, it is difficult to apply in practice. TRR encapsulation is inspired by the core-shell structures such as cells, seeds, eggs, and fruits in nature. In these natural products, the shell isolates the core from the outside, and has to break as needed to expose the core, such as in seed germination, chicken hatching, etc. Similarly, TRR encapsulation avoids direct contact between the TRR and the electrolyte, so it does not affect the electrochemical performance of the battery during normal operation. When lithium-ion battery (LIB) thermal runaway occurs, the capsules release TRRs to slow down and even prevent further thermal runaway. This review aims to summarize the fundamentals of bioinspired TRR capsules and highlight recent key progress in LIBs with TRR capsules to improve LIB safety. It is anticipated that this review will inspire further improvement in battery safety, especially for emerging LIBs with high-electrochemical performance.

Covid‐19 has given us a new way to look at our globe with regards to minimise air and noise pollution and thereby upgrading global environmental conditions. This positive pandemic outcome indicates that green energy is the future of energy, and one new origin of green energy is lithium‐ion batteries (LIBs). Electric vehicles are constructed with LIBs, but they have a number of disadvantages, including poor thermal performance, thermal runaway, fire dangers and a higher discharge rate in low‐ and high‐temperature conditions. The underlying fault of LIBs is their temperature reactivity. Extreme temperatures and challenging working circumstances can cause lithium‐ion cells to malfunction and cause the battery pack (BP) to overheat. For optimal performance in vehicles and long‐term LIB durability, LIBs must be thermally managed within their operating temperature span. This paper presents an overview of several cooling strategies used to maintain the internal BP temperature. This paper discusses cooling techniques using air, liquid and phase change material (PCM), heat pipe. Additionally, various BP configurations and heat generation techniques are explored. This research also discusses the usage of nanomaterials to address the BP's heat‐related problems. This study emphasises the use of nanomaterial to boost the heat conductivity of coolant in order to raise the batteries temperature into their ideal working range (PCM as well as liquid cooling). This article also provides some of the research gaps that have been found and the crucial areas on which attention should be directed in order to build the best lithium‐ion battery thermal management system technology.
