　　UPS lithium battery production workshop requirements and production process precautions. The UPS lithium battery production workshop is inaccessible to ordinary people due to strict requirements on environmental cleanliness. The main processes of lithium battery production, in order, are pole pieces, assembly and formation. The most important factor controlling lithium battery manufacturing is that they must be produced in dry rooms with very strict humidity conditions, as low as 1% to 10%RH.

　　What are the requirements for UPS lithium battery production workshop?

　　UPS lithium battery production workshops generally have very high requirements. Generally, the following conditions must be met to make a good product.

　　First, a fully enclosed dust-free workshop to create excellent quality

　　The UPS lithium 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 capabilities to create high-quality products

　　We use 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

　　Each production line of UPS lithium batteries has at least quality inspectors for tracking and testing, and is professionally controlled in accordance with strict quality management processes. Through incoming 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 are used to ensure battery quality and provide customers with safe and reliable products.

　　UPS lithium battery warehouse handling requirements

　　(1) Warehouse managers should check cargo information every day. If they find incorrect storage locations, inconsistent accounts, or quality problems, they should provide timely feedback and handle them. After work or after get off work, they should conduct fire inspections 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 a timely manner, and organize the materials in the warehouse into the designated area to meet the neat, tidy, clean, hygienic and reasonable placement requirements.

　　(3) Keep safe passages clear in the warehouse and prevent accumulation of debris to ensure personnel safety.

　　(4) The planned area in the warehouse must be clearly marked, and the material placement area must be classified and stored in separate areas with clear markings.

　　UPS lithium battery production process precautions

　　The UPS lithium battery production process has some differences depending on the different lithium battery manufacturers, but because the principles are the same, the main lithium battery production processes are basically the same, generally including: batching, coating, rolling, cutting, and slitting , welding tabs, winding, packaging, baking, liquid injection, formation, molding, volumetric testing and other processes.

　　Among the necessary steps in the UPS lithium battery production process, five aspects should be paid attention to from material selection to volumetric testing after molding.

　　1. Improve the physical and chemical structure of the positive and negative active materials, which is the basic link in the lithium battery production process;

　　2. The high bonding strength of the electrode coating is conducive to reducing the cycle capacity decline rate. This is the most technical process in the lithium battery production process;

　　3. Optimization of the composition of the electrolyte. The UPS lithium battery production process requires the electrolyte to maintain capacity and extend battery life;

　　4. After the battery material preparation is completed, the lithium battery production process enters the assembly process. At this time, it should be noted that the negative electrode capacity is slightly larger than the positive electrode capacity;

　　5. When performing capacitance testing, it is advisable to charge at a low rate in accordance with national standards, usually 0.2C.

　　The time for each step in the lithium battery production process is different. Generally, the ingredients, baking, and formation time are long, ranging from about 10 hours to two days and two nights at most; other processes are faster, averaging 5 or 6 times. Hour. The entire lithium battery production process takes about 15 days. In general, the following proportional relationships should be paid attention to during the process manufacturing stage: the electrode plate surface and the electrode plate compaction density, the negative electrode excess rate, the formula process, and the appropriate amount of electrolyte and positive and negative electrodes.

　　In recent years, my country's new energy vehicle industry has been booming and 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. Effective control of the lithium battery production environment, especially the control of temperature and humidity, is critical to the safety and quality of lithium battery production. Promotion plays an important role.
