Abstract

The invention discloses a thermal runaway tool for a lithium battery and a test method, and relates to the field of lithium batteries. The thermal runaway tool comprises a heating aluminum plate, andadjusting screws are arranged at four corners of the heating aluminum plate; a heating pipe hole is formed in the outer side of the heating aluminum plate, a temperature sensor is arranged on the outer side of the heating aluminum plate and located on one side of the heating pipe hole, a control cabinet is connected with one side of the heating aluminum plate, a temperature display is arranged inthe control cabinet, and a power supply control switch is arranged on one side of the temperature display and located in the control cabinet. According to the invention, the heating aluminum plate, the adjusting screws, the battery anode and cathode, the heating pipe hole, the temperature sensor, the control cabinet, the temperature display and the power supply control switch are arranged; a tested battery can be clamped more conveniently, the clamping and fixing height can be adjusted, various batteries with different thicknesses can be tested flexibly, and the device is simple in structure,low in manufacturing cost and easy to circulate in the market.

Description

technical field [0001] The invention relates to the field of lithium batteries, in particular to a tool for thermal runaway of lithium batteries and a testing method. Background technique [0002] "Lithium battery" is a type of battery that uses lithium metal or lithium alloy as the positive / negative electrode material and uses a non-aqueous electrolyte solution. Due to the very active chemical properties of lithium metal, the processing, storage, and use of lithium metal have high environmental requirements. Very high. With the development of science and technology, lithium batteries have become the mainstream. Battery thermal runaway refers to a cumulative increase in current and battery temperature when the battery is charged at a constant voltage and gradually damaged. [0003] With the large-scale popularization of electric vehicles, we have more and more opportunities to see and come into contact with electric vehicles, but many people still have doubts about the safet...
