　　Lithium-ion battery production process,CR2032 button cell battery production line

　　Lithium-ion battery production technology,CR2032 button cell battery production line. Objectively speaking, the lithium-ion battery production process is divided into three major sections, one is pole piece production, the other is cell production, and the third is battery assembly. The production process of lithium batteries is not very consistent for each manufacturer. Every link in the lithium battery production line must be strictly and carefully managed, so as to improve the safety performance of lithium battery products.

　　Lithium-ion battery production process

　　Stirring, coating, winding, and testing are the main production processes of lithium batteries.

　　1. Slurry stirring is an important part of lithium-ion battery equipment. The positive electrode slurry of lithium-ion batteries is composed of adhesives, conductive agents, positive electrode materials, etc., and the negative electrode slurry is composed of adhesives, graphite carbon powder, etc.; positive and negative electrodes The preparation of slurry includes the mixing, dissolution, and dispersion of liquids and liquids and liquids and solid materials. The quality of slurry dispersion directly affects the quality and performance of lithium-ion batteries.

　　2. Coating determines the consistency and excellence of the battery and occupies a technical position in battery manufacturing. Regardless of the type of battery produced (cylindrical or prismatic, for example), the coating machines used in manufacturing are the same; different types of batteries require different types of winding machines.

　　3. In addition to lithium-ion battery winding machines, there are also capacitor winding machines, textile winding machines, etc. According to the operation mode of the machine, it can be divided into manual winding machine, semi-automatic winding machine and fully automatic winding machine.

　　4. The importance of testing items has become increasingly prominent. Lithium-ion batteries are easy to burn or explode due to short circuit, overcharge, etc. In applications, they will be combined with protective boards to form finished batteries; in applications with high energy density, lithium-ion batteries need to be combined in series and parallel to form a lithium-ion battery pack. managed by the battery management system (BMS).

　　It can be seen that the lithium-ion battery production process is relatively long, including more than 50 processes, and correspondingly requires more than 50 types of equipment. The entire manufacturing process can be divided into four process sections: pole piece production, cell assembly, cell activation detection and battery packaging. Among them, equipment related to pole piece production is called front-end equipment, cell production-related equipment is mid-range equipment, and cell activation detection is and battery packaging devices are back-end devices.

　　In recent years, lithium battery production has developed toward integration, line-integration, and automation. Lithium battery automated production lines provide customers with standardized products. Traditional development methods cannot cope with the rapidly changing needs of customers.

　　The quality of lithium batteries is of vital importance. The main problem in the current domestic lithium-ion battery industrialization is poor battery quality consistency. The reason is mostly due to manual operation and poor equipment accuracy resulting in large system errors and the inability to produce continuously. To fundamentally solve the problem of poor quality consistency in batch production of lithium-ion batteries, we must also improve the control accuracy of production equipment and the level of automation of the production line.

　　Lithium battery pack production line

　　There are many production processes before the formation of lithium batteries, the largest of which follows this line: precursor material → battery cell component → lithium battery → lithium ion battery/lithium battery pack. In the industry, there are multiple manufacturers engaged in the same production, and there are also one manufacturer engaged in multiple productions.

　　The lithium battery automated production line can realize fully automatic code scanning-injection-weighing-replenishing-sealing operations in a super purified glove box, achieving efficient and completely unmanned automated production, greatly saving labor costs, and greatly improving production capacity, product quality and finished products. efficiency to maximize benefits for customers.

　　What processes does theCR2032 button cell battery production line contain?

　　1. Sorting and grouping process

　　2. Automatic welding process

　　3. Semi-finished product assembly process

　　4. Aging test process

　　5. PACK detection process

　　6. PACK packaging technology

　　In the entire process from lithium battery cells to automated modules to PACK production lines, the degree of automation of the assembly line is a key factor in determining product quality and production efficiency. In order to further improve production efficiency and reduce costs, the application of automated production equipment must be vigorously promoted.
