[0002] During the production process of cylindrical lithium batteries, defective batteries often occur, manifested as abnormal conditions such as zero voltage, heating, and explosion and spraying; especially in the formation and high-temperature aging processes in the fully charged state, the risk is the highest; in a fully automatic three-dimensional warehouse, once an explosion and spraying occur, the loss is relatively large; before the battery explodes and sprays, it will definitely heat up first, so the monitoring of the heated battery is crucial.

[0003] There is a temperature sensor probe for monitoring in real time during the formation process. However, there is no temperature monitoring from the outflow to the inflow of the high-temperature stage during formation, which is likely to cause the internally short-circuited and heated battery after formation to flow into the high-temperature stage. Due to the high temperature, the internal reaction speed of the battery is accelerated, and the heat generation and gas production speed are increased until an explosion and spraying occur.

[0004] Therefore, there is an urgent need for a lithium-ion battery risk detection device for monitoring the temperature of the battery during the outflow stage of formation. Summary of the Utility Model
