How can thermal management improve battery safety?

Understanding thermal runaway and propagation mechanisms in various systems and developing corresponding prediction technologies are essential for improving battery safety. From a thermal perspective, thermal management approaches capable of interrupting the chain exothermic reactions help to address thermal runaway of batteries.

How do batteries react to external temperature variations and internal heat generation?

The reaction of batteries to external temperature variations and internal heat generation significantly relies on the thermal material properties of the cells, specifically the specific heat capacity and thermal conductivity.

What is a thermal-based strategy for battery thermal safety?

Once thermal runaway and fire incidents occur, enhancing heat dissipation capacity and fire suppression capability represents the effective thermal-based strategy to mitigate thermal runaway propagation and contain fire hazards, ultimately ensuring battery thermal safety.

How does heat conduction occur in a battery?

Heat conduction primarily occurs through surface contact between adjacent batteries 25. Heat convection arises from density gradients in air surrounding the battery owing to localized high temperature, with additional convective flow generated by vented gases during thermal runaway 26.

How can a cooling spray improve the thermal safety of batteries?

In addition to thermal management strategies, improving the thermal stability and flame retardancy of internal battery materials is a critical approach to enhancing the thermal safety of batteries. In terms of fire prevention, cooling sprays have proven to be effective.
