What is the mechanism of particle ejection of lithium-ion batteries during thermal runaway?
Mechanism of particle ejection of lithium-ion batteries during thermal runaway. The above mechanisms indicate that the high-speed spouting gases carry the solid particles during the cell venting.
How many G does a battery eject?
It was found that the solids and electrolyte vapours occupied the major release of venting materials, which were calculated as 7.19 g and 3.15 g, respectively, for the primary ejection. Subsequently, the battery mass presented a persistent decline until the internal decomposition reactions ended, and the battery went into a cooling stage.
What happens when a particle is ejected from a safety valve?
After being ejected from the safety valve, the particles will be driven owing to the energy exchange from gas to solid and carried by the jet flow. Meanwhile, some reactions, such as the oxidation of particles, will occur, leading to the mass loss of the discrete phase.
What is the gradient of L in a prismatic battery?
The gradient of αl is assumed to be uniform along the axial direction of the battery. l1 and l2 are the size parameters of the prismatic battery, as 26 mm and 148 mm. 2.3.2. Pressure accumulation and venting During TR, the pressure inside the cell will accumulate due to gas generation and electrolyte evaporation.
How much ejection energy does a cell release?
In addition, the amount of self-heating energy from TR can be estimated according to the conservation between the heat to increase cell temperature, the heat from external heating and the heat dissipation on the cell surface, calculated as approximately 268.91 kJ. The ejection energy accounts for about 17.69% of the total energy release of TR.
How is ejection energy calculated?
The ejection energy is calculated as approximately 47.58 kJ. In addition, the amount of self-heating energy from TR can be estimated according to the conservation between the heat to increase cell temperature, the heat from external heating and the heat dissipation on the cell surface, calculated as approximately 268.91 kJ.
