Lithium-ion batteries (LIBs) are currently the most preferred secondary sources of energy due to their intrinsic properties such as high energy density, and longer life cycle as compared to the other available batteries. However, it faces a significant challenge related to thermal safety concerns such as thermal runaway when utilized over an extended period, prolonged charging, and the use of incompatible electrolytes or separators with low stability. Addressing the safety concerns of Lithium-ion Batteries (LIB) is not a matter of an immediate solution, given the multitude of external and internal factors involved. Therefore, a comprehensive approach is required, spanning from the manufacturing process to end-use, to tackle this highly critical challenge associated with LIB effectively. The mechanism of thermal runaway commences from the time of its first cycling process, which involves the transfer of ions from the anode to the cathode via electrolyte medium and vice-versa and separator in-between acting as a barrier to their free movement. As time passes, the electrolyte degrades and is resistant to absorbing heat, resulting in breaking the SEI (solid electrolyte interface), and the dendrite structure is formed gradually leading to a short-circuit. The abnormal rise in the temperature of the cell beyond a threshold point and thermal runaway results in an explosion of the cell. In this paper, the authors have reviewed some of the recent works done by the researchers on this critical issue starting from its initiation, gradual development to intensification, and final stage of blasting. Here, the roles played by various cell elements have been studied in detail on the available research data. Then, an analysis has been made of this study and a few recommendations have been proposed at the end, which, the authors think, will help to a great extent to mitigate the issue of TR(thermal runaway) in LIB and clear the roadway for a safe and sustainable design in future.
