AI Technical Summary

Technical Problem

The environmental pollution caused by emissions from battery devices under thermal runaway conditions, especially the impact of flue gas concentration and temperature on the environment, has not been effectively controlled.

Method used

Design a battery device comprising a housing, battery cell assembly, and an exhaust pipe. The exhaust pipe is connected to the housing and is used to collect and discharge emissions from the battery cells. By incorporating bends and widening sections within the exhaust pipe to increase the flow path of the flue gas, heat exchange and solid particle deposition are promoted, thereby reducing the concentration and temperature of the flue gas.

Benefits of technology

It effectively reduces the concentration and temperature of flue gas emitted during thermal runaway of battery devices, reduces environmental pollution, and improves the condensation effect and safety of emissions.
