Numerical Study on the Inhibition Control of Lithium-Ion Battery Thermal Runaway

摘要

To solve the problem of thermal runaway is one of the necessary conditions for the commercialization of lithium-ion batteries. In order to further explore the reaction mechanism of thermal runaway of lithium-ion batteries, a thermal model is built by using a variety of side reactions to further study the inhibition of temperature on thermal runaway. The results show that thermal runaway is triggered by the heat generation of negative material reaction when it is heated to 473.15 K; lower heat dissipation temperature (273.15 K) cannot effectively inhibit the occurrence of thermal runaway.
