With the charging and discharging, the heat accumulates and the battery temperature rises steadily, which eventually leads to the occurrence of thermal runaway, which may cause a fire or an explosion. In recent years, many scholars have studied the thermal behavior of lithium-ion batteries during charging and discharging.
Intact Lithium-ion batteries are considered to be Universal Waste (i.e. a subset of the hazardous waste regulations intended to ease the burden of disposal and promote the proper collection, storage, and recycling of certain materials). Damaged Lithium-ion batteries are considered to be Hazardous Waste and must be collected through the EHS Office.
When the lithium-ion battery is discharged at a slow rate, the heat of reaction will occupy the main part. When the battery is discharged at a high rate, Joule heat occupies the main part [9].
Their research showed that the total thermal behavior of lithium-ion battery during charging and discharging was exothermic, and the heat generation increased with the increase of charging and discharging current.
The internal failure of a LIB is caused by electrochemical system instability , . Thus, understanding the electrochemical reactions, material properties, and side reactions occurring in LIBs is fundamental in assessing battery safety. Voltage and temperature are the two factors controlling the battery reactions.
The thermal safety of LIBs is a hot but complex topic for battery research, development, and application. Improving the safety of LIBs is very important for their sustainable development. The safety standards play a critical role in promoting the safety of LIBs. The standards should be constantly revised and evolved with the development of LIBs.

Generally speaking, over discharge can increase the internal pressure of the battery, disrupt the reversibility of positive and negative active substances, decompose the electrolyte, deposit lithium on the negative …
The results show that high-rate discharge is more likely to cause battery overheating, leading to thermal runaway. High-rate charging operation with cut-off voltage control fault is dangerous because it will lead to high-speed heat generation, which may eventually lead to thermal runaway. To sum up, the thermal runaway behavior of single LIBs and the thermal …

Lithium-ion batteries (LIBs) have become the absolute mainstream among all EV power sources due to their advantages, such as their high energy density, excellent life cycle performance, and high charge–discharge efficiency [7, 8, 9]. The global installed capacity of LIBs in EVs is expected to reach 357.5 GWh in 2022 [10].
To analyze the impact of two commonly neglected electrical abuse operations (overcharge and overdischarge) on battery degradation and safety, this study thoroughly investigates the high current overcharge/overdischarge effect and degradation on 18650-type Li-ion batteries (LIBs) thermal safety.
Numerous lithium-ion battery (LIB) fires and explosions have raised serious concerns about the safety issued associated with LIBs; some of these incidents were mainly caused by overcharging of LIBs.
Generally speaking, over discharge can increase the internal pressure of the battery, disrupt the reversibility of positive and negative active substances, decompose the electrolyte, deposit lithium on the negative electrode, increase resistance, and even if charged, only partially recover, resulting in a significant decrease in capacity.
