AI Customer ServiceSee all authors As the energy density of lithium-ion cells and batteries increases, controlling the outcomes of thermal runaway becomes more challenging. If the high rate of gas generation during thermal runaway is not adequately vented, commercial cell designs can rupture and explode, presenting serious safety concerns.
Gas generation dynamics of Li-ion battery during thermal runaway is investigated. Relationship between gas and heat producing rates is revealed. Multi-stage kinetics parameters help predict the pressure and venting. The gas generation and rupture are the special features of the thermal runaway (TR) of lithium-ion batteries (LIBs).
The casing rupture occurred in two forms, namely, a melting hole and a tearing crack, which inevitably caused TR propagation in the battery module and pack. The formation mechanism of the casing rupture was investigated by triggering TR in commercial cylindrical 21700 lithium-ion batteries.
Three element factors of lithium ion battery combustion under overcharge were clarified. The location of the ignition point at a charge rate of 2C was determined. To clarify the evolution of thermal runaway of lithium-ion batteries under overcharge, the prismatic lithium-ion batteries are overcharged at various current rates in air and argon.
Based on our experiments, almost all the commercial cylindrical lithium-ion batteries have a certain possibility of casing rupture in a large number of external heating TR tests, and this possibility is affected by the design of the battery, such as the anode/cathode material composition, the vent threshold, and the electrode thickness.
Lithium-ion batteries (LIBs) present fire, explosion and toxicity hazards through the release of flammable and noxious gases during rare thermal runaway (TR) events. This off-gas is the subject of active research within academia, however, there has been no comprehensive review on the topic.
