Thermal runaway (TR) in lithium-ion batteries is a process where uncontrolled heat generation leads to fire and explosion. The prevention of TR is vital as the technology is pushed to its limit of power and energy delivery in applications such as electric vehicles. TR has been responsible for several high-profile accidents and product recalls over the past decade.
Several reviews have focused on the mechanism and diagnosis of internal short circuits (ISC) of Li-ion batteries. Liao et al. conducted a full review of the mechanisms and causes that can lead to thermal runaway in Li-ion batteries, and of approaches to monitoring and detecting it.
At present, there are many prevention and mitigation methods for battery thermal runaway, such as the detection and early warning of battery thermal runaway. In order to determine whether the battery thermal runaway happens, it can be used to monitor the voltage, current, temperature, and internal resistance .
Thermal runaway prevention is explained. Thermal runaway is still a challenging problem in electric vehicle applications. Lithium-ion batteries are widely considered the leading candidate energy source for powering electric vehicles due to their high energy and power densities.
5.1. Thermal runaway mitigation mechanism Thermal runaway in a battery pack can lead to fire hazards. The fire occurs when the mixture of battery fuel and oxidizer is exposed to high heat sources. The combustion can be halted through the following mechanisms: There are five types of basic extinguishants used to extinguish battery fires.
Thermal runaway is associated with chemical reactions, short circuits, smoke, fire, and explosion, making the situation more complicated than we can imagine. The real process that drives the failure hides behind deceptive observations. This perspective proposes mitigation strategies for the thermal runaway problem of lithium-ion batteries.
