Energy storage safety thermal runaway

What is battery thermal runaway?

Battery thermal runaway is a serious issue that demands attention, especially as the use of battery-powered systems becomes more widespread. By understanding the causes and risks associated with thermal runaway, and by implementing effective prevention strategies, you can protect your battery systems from catastrophic failures.

Why is thermal runaway a major safety concern?

As thermal runaway is a major safety concern, therefore, the mathematical and numerical models are summarized, which are required to predict and develop the safety behaviors of batteries and optimize the battery thermal management system designs to prevent thermal runaway.

What is thermal runaway prevention?

Thermal runaway prevention is explained. Thermal runaway is still a challenging problem in electric vehicle applications. Lithium-ion batteries are widely considered the leading candidate energy source for powering electric vehicles due to their high energy and power densities.

How can battery thermal management prevent thermal runaway initiation?

Furthermore, the development of effective battery thermal management systems is discussed, which is essential to prevent thermal runaway initiation. Finally, mitigation strategies are reviewed, which are developed to contain and minimize damages when thermal runaway occurs.

What are the key aspects of the thermal runaway process?

This paper provides a comprehensive review of the key aspects of the thermal runaway processes, which consists of thermal runaway initiation mechanisms, thermal runaway propagation, and the characterization of vented gases during the thermal runaway process.

How does thermal runaway affect the energy release of a battery?

The battery was subjected to a ramp heating method to depict thermal abuse conditions. The results showed that the internal pressure and the maximum surface temperature of the battery increased with the SOC increase when thermal runaway occurred. The authors calculated the energy release of the completely charged fresh battery to be 61.72 kJ.
