Abstract: The purpose is to explain how to apply thermal conductive adhesive correctly, maximize the thermal conductivity of thermal conductive adhesive, and improve the thermal management efficiency of power batteries during use. This paper summarizes the application of thermal conductivity adhesive in power battery, analyzes the common failure mode of thermal conductivity adhesive in process application process and the possible causes such as substandard thermal conductivity adhesive, equipment parameter setting, surface cleanliness, etc., and puts forward application suggestions and countermeasures for thermal conductivity adhesive viscosity and process control. The quality control of the coating of thermal glue is carried out through the quality management tool of statistical process control (SPC). Thereby improve the power performance, safety performance, and service life of power batteries. At the same time, it also contributes to the application of thermal conductive adhesive in the battery industry engineering in China.
