Breakdown of components: Heat or damage can cause internal battery components to break down, releasing gases and generating more heat.

We studied the thermal runaway process of lithium-ion batteries (LIBs) caused by thermal abuse, with a particular focus on the effects of combustion. First, we observed a gradual increase in battery temperature during thermal runaway until it reached 190 °C, at which point it sharply rose to approximately 500 °C. However, thermal runaway induced by combustion was

The combustion process can be divided into four stages, which were ignition, violent combustion, stable combustion and extinguishing stages.

Combustion of lithium-ion batteries may be triggered by the thermal runaway pro- cess due to the mechanical, thermal, and electrical abuse of batteries. Thermal runaway normally refers to the uncontrollable temperature rise of a lithium-ion battery caused by internal exothermic reactions. Thermal abuse is one of the main reasons for the thermal runaway of

The fuel, oxygen and energy provide the probability of fire and explosion, as the lithium ion battery is a closed system, so the gas products cause the increasing of the inner pressure and the exothermic heats heat up the system. With the rising up of the battery temperature, more chemical reactions occur, and more heat generation.
At elevated temperatures, oxygen released from the cathode can react intensely with the electrolyte or anode, drastically raising the battery's temperature. The greater the amount of lithium retained in the anode (the higher the SOC), the greater the energy release upon reaction, and, consequently, the higher the risk of thermal runaway.
Here, the combustion triangle theory was used to explain the battery fire and explosion. The three components are also necessary for combustion or burning in lithium ion battery. The main fuel in lithium ion battery is electrolyte, which is a solution consists of organic solvent and inorganic salt.
Safety problem is always a big obstacle for lithium battery marching to large scale application. However, the knowledge on the battery combustion behavior is limited.

Thermal runaway is the main cause of lithium-ion battery accidents. A major trend in battery development is to increase the capacity of individual batteries, and large-capacity batteries tend to cause more serious damage when thermal runaway occurs.
The combustion process of the battery can be divided into four stages, and the aggressive cylindrical flame is observed. The flaming combustion accelerates the occurrence of TR but has little influence on the peak surface temperature.
