Title:
THERMAL RUNAWAY EXPERIMENT DEVICE AND USE METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2024/065202
Kind Code:
A1
Abstract:
The present application relates to the technical field of batteries, and provides a thermal runaway experiment device and a use method therefor. The thermal runaway experiment device comprises a heating mechanism and a cooling mechanism. The heating mechanism is internally provided with a reaction cavity used for accommodating a battery cell, and the heating mechanism is configured to heat the battery cell to trigger thermal runaway of the battery cell. The cooling mechanism is configured to provide a cooling medium in the reaction cavity to cool the battery cell, so that thermal runaway of the battery cell is aborted. According to such a thermal runaway experiment device, the battery cell can be cooled at any stage or any temperature point in the thermal runaway experiment of the battery cell, and the thermal runaway reaction is aborted, so that the internal reaction mechanism of the battery cell at any stage and any temperature point in the thermal runaway process can be researched, which is beneficial to reducing the difficulty of revealing the cause of thermal runaway of the battery cell, the problem of thermal runaway of the battery cell can be found and solved in a targeted manner, and an important theoretical reference is provided for the safety design of the battery cell.
