CR1625 battery production workshop requirements and production process notes

CR1625 battery production workshop, due to the strict requirements for environmental cleanliness, ordinary people cannot enter. The main processes of lithium battery production, in order, are pole piece, assembly and formation. The most important factor controlling the manufacture of lithium batteries is that they must be produced in a drying room, and the humidity conditions are very strict, as low as 1% to 10%RH. What are the requirements for CR1625 battery production workshops? CR1625 battery production workshops generally have very high requirements. Generally, the following conditions must be met to make good products. First, a fully enclosed dust-free workshop to create excellent quality. The CR1625 battery production workshop adopts a fully enclosed dust-free workshop, which can strictly control the temperature, humidity and dust of the environment during the product production process, thereby ensuring the excellent quality of the product. Second, large-scale and automated production capacity to create high-quality products uses advanced automatic production equipment at home and abroad to minimize the incidence of defective products and ensure stable manufacturing standards and supply capabilities. Third, each process must have perfect quality control. There must be at least one quality inspector on each CR1625 battery production line to conduct follow-up inspections and professionally control according to strict quality management processes. Through incoming material quality control (IQC), process quality control (IPQC), outgoing quality control (OQC), battery reliability and safety performance testing, customer service, quality engineering, instrument calibration and system management, the battery quality is ensured to provide customers with safe and reliable products. CR1625 battery warehouse handling requirements (1) Warehouse management personnel must check the cargo information every day. If they find that the storage location is incorrect, the account does not match the goods, or the quality problem is found, they should promptly feedback and handle it. When the work is over or off duty, they should conduct a fire prevention inspection and cut off the power supply. (2) Clean and organize the warehouse area every day, clean up the dirt and debris on the ground in time, and organize the materials in the warehouse into designated areas to achieve neat, orderly, clean, sanitary and reasonable placement requirements. (3) Keep the safe passages in the warehouse unobstructed, eliminate accumulation of materials, and ensure the safety of personnel. (4) The planned areas in the warehouse must be clearly marked, and the material placement area must be classified and stored in small areas with clear markings. CR1625 battery production process precautions CR1625 battery production process varies from different lithium battery manufacturers, but due to the same principle, the main lithium battery production process is basically the same, generally including: batching, coating, rolling, cutting, striping, welding pole ears, winding, packaging, baking, injection, formation, molding, capacity detection and other processes. In the necessary steps of CR1625 battery production process, five aspects should be paid attention to from material selection to capacity detection after molding: 1. Improve the physicochemical structure of positive and negative active materials, which is the basic link of lithium battery production process; 2. The high bonding strength of electrode coating is conducive to reducing the cycle capacity decline rate, which is the most technical process in lithium battery production process; 3. Optimization of electrolyte composition, CR1625 battery production process requires electrolyte to maintain capacity and extend battery life; 4. After the preparation of battery materials, the lithium battery production process enters the assembly link, at this time, it should be noted that the negative electrode capacity is slightly larger than the positive electrode capacity; 5. When testing the capacity, it is advisable to charge at a low rate according to national standards, generally 0.2C. Each step in the lithium battery production process takes different time. Generally, the batching, baking, and formation time are long, ranging from about 10 hours to two days and two nights; other processes are relatively fast, averaging 5 or 6 hours. The entire lithium battery production process takes about 15 days. In general, the following proportional relationships should be paid attention to in the process manufacturing stage: the compaction density of the pole surface and the pole, the excess rate of the negative electrode, the formulation process, and the applicable amount of electrolyte and positive and negative electrodes. In recent years, my country's new energy vehicle industry has flourished and has been favored by more and more consumers. Industrial dehumidifiers are very important in lithium battery production workshops. Lithium batteries need to strictly "avoid" moisture and dust in the air, and the effective control of the lithium battery production environment, especially the control of temperature and humidity, plays an important role in improving the safety and quality of lithium battery production.
