Precautions for high temperature of energy storage batteries

Do high temperature conditions affect thermal safety of lithium-ion batteries?

The thermal safety performance of lithium-ion batteries is significantly affected by high-temperature conditions. This work deeply investigates the evolution and degradation mechanism of thermal safety for lithium-ion batteries during the nonlinear aging process at high temperature.

What is battery thermal safety?

The control of heat generation, effective thermal management and robust fire suppression strategies are key to ensure battery thermal safety and will have a crucial role in the development and large-scale application of batteries. Excessive heat generation in batteries can result in thermal runaway and fires incidents.

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 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.
