“…The silicon, whether it is crystalline or amorphous, will be transformed into an amorphous phase and then into a crystalline compound in the lithium intercalation process [13,26]. In the temperature range of 110-300 • C, the cathode has experienced a series of phase transitions from a layered structure to a M 3 O 4 spinel to rock salt [21,27,28]. Both of these processes require the release of a large amount of oxygen, which reacts with the electrolyte and releases a large amount of heat.…”

The lithium-ion battery industry has been developing rapidly, with energy density and capacity constantly improving. However, the ensuing safety accidents of lithium-ion power batteries have seriously threatened the personal safety of passengers. Therefore, more and more attention has been paid to the thermal safety research of lithium-ion batteries, such as thermal runaway (TR) mechanism analysis and prevention methods, etc. In this paper, the nickel-rich 18650 lithium-ion batteries with Li[Ni0.8Co0.1Mn0.1]O2 cathode in different states of charge (SOC) are taken to investigate the TR characteristics using an extended volume plus acceleration calorimeter (EV+-ARC). In order to evaluate the TR characteristics, some characteristic parameters such as battery voltage, surface temperature, temperature rise rate, etc. are selected from the experiment to analyze the influence of SOC on the critical state of TR. It can be seen from the experiment results that the maximum temperature of the battery surface decreases with the decrease of SOC, while the self-generated heat temperature and TR trigger temperature increases with the decrease of SOC.

“…Boehmite (AIOOH) belongs to inorganic-based metal hydroxides. Its decomposition is a highly endothermic reaction, forming alumina (Al 2 O 3 ) powder and releasing water while absorbing significant heat, as shown in Figure 2B and Equation (8). The released water both lowers the temperature and dilutes combustible gases.…”

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.

“…5 However, the cathode materials with high nickel content are reported to suffer from low thermal stability, leading to safety problems, for example, thermal runaway. [6][7][8] Therefore, understanding the thermal stability of Ni-rich cathode materials as well as the thermal runaway of batteries have become urgent for the large-scale application of Ying Sun and Dongsheng Ren contributed equally to this study. high energy density lithium ion batteries in electric vehicles.…”

“…Several researchers have also investigated the thermal stabilities of Ni-rich cathode materials and derived similar conclusions. 6,31,32 However, the safety performance of lithium ion batteries should be evaluated within a full battery, where the cathode materials are soaked in electrolyte and might also react with lithiated anodes. The correlation between thermal stability of Nirich cathode materials and thermal runaway of lithium ion batteries remains unclear and requires further investigation.…”
