Lithium battery thermal runaway fireproof materials

What is thermal runaway in lithium-ion batteries?

The prevention of thermal runaway (TR) in lithium-ion batteries is vital as the technology is pushed to its limit of power and energy delivery in applications such as electric vehicles. TR and the resulting fire and explosion have been responsible for several high-profile accidents and product recalls over the past decade.

Can lithium-ion battery systems prevent thermal runaway propagation?

At the same time, mitigating the potential for thermal runaway (TR) propagation in lithium-ion (Li-ion) battery systems has become a key safety goal of regulatory bodies, vehicle manufacturers, and all other participants in the EV market .

Can thermal insulating materials prevent thermal runaway?

In the wake of increasing cases of Li-ion battery fires, we study the performance of different thermal barrier materials for preventing thermal runaway (TR) due to cell-to-cell thermal runaway propagation. In this study, firstly, we characterize the performance of the available thermal insulating materials through a blow torch test.

What happens if a lithium ion battery combusts during thermal runaway?

Multiple requests from the same IP address are counted as one view. During thermal runaway (TR), lithium-ion batteries (LIBs) produce a large amount of gas, which can cause unimaginable disasters in electric vehicles and electrochemical energy storage systems when the batteries fail and subsequently combust or explode.

Why is thermal runaway prevention important?

5. Thermal runaway prevention The prevention of TR and the inhibition of heat propagation in the event of TR in LIBs are paramount concerns for ensuring the safety and reliability of these energy storage devices .

Are multicell lithium-ion batteries fire resistant?

There is major fire safety concern about failure propagation of thermal runaway in multicell lithium-ion batteries. This article overviews the passive fire-protection approach based on thermal insulation by intumescent coating materials and fire blankets for viable failure resistance.
