What happens if a battery reaches a safe temperature limit?
Higher temperatures accelerate side reactions, and if the battery exceeds its safe operating temperature limit, self-heating may trigger further exothermic reactions, known as the heat-temperature-reaction (HTR) loop [106, 107]. This process can lead to thermal runaway, posing thermal safety issues.
Do lithium-ion batteries have thermal safety?
Thermal safety of aging batteries: Ensuring the continuous operation of lithium-ion batteries hinges on their thermal safety. Current research primarily analyzes the aging condition of batteries in terms of electrochemical performance but lacks in-depth exploration of the evolution of thermal safety and its mechanisms.
Does temperature affect a battery's thermal runaway behavior?
Unlike the thermal runaway behavior changes observed in batteries aged under high temperatures—where aged batteries exhibit delayed thermal runaway compared to new batteries—those aged under low temperatures show worse thermal runaway behavior, with more severe temperature rises and mass loss .
Do aging batteries have thermal safety?
Current research primarily analyzes the aging condition of batteries in terms of electrochemical performance but lacks in-depth exploration of the evolution of thermal safety and its mechanisms. The thermal safety of aging batteries is influenced by electrode materials, aging paths, and environmental factors.
Can thermal runaway of lithium-ion batteries be mitigated?
Thermal runaway (TR) of lithium-ion batteries is the main cause of fire accidents in Electric Vehicles (EVs) and Energy Storage Stations (ESSs). Mitigating the TR is crucial for keeping safety of EVs and ESSs. The immersion boiling heat transfer technology is a promising candidate for mitigating TR of lithium-ion batteries.
