CR2032 button cell battery

　　What are the manufacturing processes for CR2032 button cell battery? What production and testing equipment are available for CR2032 button cell battery?

　　Lithium battery manufacturing process

　　Objectively speaking, the lithium battery manufacturing process is divided into three major sections, one is pole piece production, the other is cell production, and the third is battery assembly. In the lithium battery production process, pole piece production is the foundation, battery cell production is the core, and battery assembly is related to the quality of the finished lithium battery. The specific steps of the lithium battery production process include positive electrode slurrying, negative electrode slurrying, positive electrode sheets, negative electrode sheets, steel case assembly, liquid injection and testing, and packaging.

　　At present, the cell manufacturing processes of power CR2032 button cell battery mainly include winding and lamination. The corresponding battery structures are mainly cylindrical, square, and soft-packed. Cylindrical and square batteries are mainly produced using the winding process, while soft-packed batteries are Mainly using lamination technology.

　　What are the lithium battery production and testing equipment?

　　In the process of producing lithium battery products, lithium battery measurement has become more and more important. Maybe because of a slight error, this batch of products will become scrapped products, and this situation is most common among mass-produced manufacturers. This is also The most important point to note. Therefore, it is becoming more and more important to choose lithium battery testing equipment.

　　1. X/β-ray surface density measuring instrument

　　2. Laser thickness gauge

　　3. Multiple synchronous tracking systems

　　The production process of CR2032 button cell battery is relatively complex. The main production process mainly covers the stirring and coating stage of electrode production, the winding and liquid injection stage of cell synthesis, and the packaging and testing stage of chemical packaging. The value ratio is about (35~40% ): (30~35)%: (30~35)%. According to Coating Online, the differences mainly come from different equipment suppliers, differences in the proportion of imported/domestic products, etc. The process flow is basically the same, and the value ratio is deviated but generally consistent with this ratio.

　　The lithium battery equipment corresponding to the front-end process of lithium battery production mainly includes vacuum mixers, coating machines, roller presses, etc.; the middle-stage process mainly includes die-cutting machines, winding machines, lamination machines, liquid injection machines, etc.; the back-end process includes formation machines. , volumetric testing equipment, process warehousing and logistics automation, etc. In addition, the production of battery packs also requires Pack automation equipment.
