Strengthening the inherent safety involves improving the intrinsic properties of the battery, such as the fire-retardant characteristics of the battery components and the stability of the SEI and the cathode–electrolyte interface (CEI), and inhibiting the formation of lithium dendrites.
Herein, the causes of TR are described and novel preventative methods are examined, approaching the problem from different angles by altering the internal structure of the battery to undergo thermal shutdown or developing the battery and thermal management systems so that they can detect and prevent TR.
Thus, restricting the plating of lithium metal and reducing the reaction heat were determined to be crucial for improving and ensuring the thermal safety of LIBs during overcharge cycling. Overdischarge is another type of battery abuse that occurs if the battery is discharged to below the cutoff voltage.
To solve the battery safety problem, early warning and firefighting are the two most practical approaches. Early warning refers to real-time monitoring of voltage, current, resistance, and other data before the occurrence of a thermal hazard. An alarm is triggered when an abnormality is detected.
Residual energy in the battery, the state of charge (SOC), energy released in a battery, and DOD: These parameters are related to the diffusion rate of lithium ions, which suggests that prevention of overcharge and overdischarge of the battery is a feasible approach to avoid thermal runaway.
Battery safety involves preventing and mitigating the risks of thermal runaway, fire, explosion, leakage, and other hazards that may occur due to electrical, mechanical, or thermal abuse of the battery.
