Sealing method and recommended adhesive for battery cells

The battery market is in a stage of rapid development and innovation, mainly driven by the demand for electric vehicles (EVs). Electric vehicles have increasingly high requirements for batteries, especially in terms of energy density, lifespan, and charging speed. The advancement of solid-state battery technology has brought new hope for improving the safety and performance of batteries, especially the design of silicon anodes and lithium metal anodes, which can further enhance the performance of batteries.In this fiercely competitive market, battery manufacturers are facing pressure to improve energy efficiency, reduce costs, and comply with strict regulations. For example, they need to ensure that battery products comply with the highest flame retardant standards (such as UL94V0) and do not contain harmful substances, such as PFAS, which are regulated by the European REACH regulation. With the increasingly fierce competition in the global electric vehicle market, major manufacturers are vying for market share and striving to provide advanced and cost competitive battery solutions. Square battery. cylindrical battery, soft pack batterySealing can also affect the mechanical stability and thermal management of batteries, which is crucial for maintaining optimal performance under various operating conditions. Therefore, choosing the appropriate sealing method is crucial for ensuring the reliability and safety of battery cells.The choice of sealing method depends on the specific requirements of the battery application and the ideal balance between performance, cost, and manufacturing complexity. Lithium battery packaging formAccording to the packaging form, lithium batteries can be divided into three forms: square, cylindrical, and soft pack. The packaging form refers to the packaging structure of a single lithium battery, and different packaging forms correspond to different manufacturing processes, as well as different forms of battery precision structural components. At present, the packaging technology route for lithium batteries mainly includes three forms: cylindrical, square, and soft pack. The…
