[0002] In the application fields of lithium batteries, especially in electric vehicles, energy storage systems, etc., fire warning technology is crucial. Traditional fire warning systems mostly rely on fixed smoke sensors or temperature sensors. These sensors have limitations in detecting fires, such as slow response speed, insufficient sensitivity or inability to fully cover the working environment of lithium batteries. With the rapid development of lithium battery technology, its working environment has become more complex and changeable, which puts higher requirements on the accuracy and adaptability of fire warning systems.

[0003] Most lithium battery fire warning sensors on the market use a single type of sensor for fire warning, such as detecting fire risks only through temperature or smoke. However, lithium battery fires are often accompanied by the combined effects of multiple factors, such as abnormal temperature rise, smoke generation, gas leakage, etc. It is difficult for a single type of sensor to fully and accurately detect these fire risk factors, resulting in the risk of false alarms or missed alarms in the warning system.
