New energy battery cabinet temperature is too high

What is the temperature range of a battery?

Moreover, as batteries are developed to operate within a specific temperature range, their applicability can be limited in extreme environments in which temperature operation requirements can range from as low as −80 °C to as high as 60 °C (ref. 12).

How do thermal issues affect battery safety?

Thermal issues are a critical challenge in battery safety, directly determining the prevention efficacy of thermal runaway-induced hazards. Effective thermal runaway mitigation requires dual approaches: internally suppressing heat generation through electrochemical optimization and externally enhancing heat dissipation via thermal management.

How does thermal management affect battery performance?

Meanwhile, thermal management serves as an external approach to protect batteries against extreme temperatures, with its efficacy directly determining battery lifespan, performance and safety. Ultimately, if batteries still undergo unpredictable thermal runaway, fire suppression strategies become the final safeguard.

How does temperature affect reversible chemical reactions in a battery?

Operating within a suitable temperature range keeps the main reversible chemical reactions of the battery in a stable equilibrium, while side reactions (such as electrolyte decomposition or electrode material breakdown), which require higher activation energy, are inhibited 118.
