Can new energy battery cabinets be used at high temperatures

How can battery thermal safety be improved?

Mitigating the occurrence of thermal runaway is crucial to ensure battery thermal safety. The primary approach to achieve that involves understanding the mechanisms and patterns of heat generation during thermal runaway and subsequently addressing these internal heat-related issues through mitigation 9.

Are battery materials safe or performance-temperature-independent?

However, there are no battery materials or systems that can be deemed absolutely safe or performance-temperature-independent. In this Perspective, we discuss battery safety from a thermal point of view and emphasize the importance of battery thermal management.

Why is thermal management important in a battery?

When absolute safety cannot be assured in battery materials and systems, thermal management becomes the primary barrier to battery thermal risks. However, owing to the extremely rapid rate of exothermic side reactions, the importance of fire suppression becomes evident when thermal runaway cannot be contained, leading to fire accidents.

Are lithium-based batteries thermally stable?

From the perspective of the battery, the thermal behaviour of lithium-based batteries depends considerably on their underlying chemistry. Lithium iron phosphate cells typically demonstrate a higher thermal stability and lower susceptibility to thermal runaway, albeit at the expense of lower energy density.
