Dry hot air impact drying process for lithium batteries

South Korean lithium battery dry hot air impingement drying technology This article analyzes a new process for shock wave transpiration drying and dehydration of lithium battery electrodes, battery cells and batteries before injection. Use super-capacity dehumidification equipment. The process of impulsive transpiration drying and water circulation is to separate less than 5ppm of dry air into the drying chamber of the oven to treat the bakeware, batteries and batteries before injecting liquid to impinge transpiration. After the moisture is dried, the impulsive transpiration is the super wet capacity analysis equipment and the drying cycle is separated. The continuous treatment of the pole piece, battery, battery and liquid jet impact transpiration. Before drying, the strong wet equipment analysis ability continuously separates water, dry air and recycling, which greatly reduces the energy consumption of heating. Detailed advantages: (1) Large drying chamber capacity: large drying capacity, especially suitable for processing high-power batteries and large batteries. (2) The moisture content of dry air is low; the moisture content of dry air is less than 5PPM, which is 1900ppm lower than pure nitrogen, which is 99.9%. The nitrogen content is 5PPM lower than the purity of 99.99%. (3) Low drying temperature: The drying temperature is 15-20℃ lower than that of the traditional vacuum oven, and the gap shortening and deformation are very small, which has no effect on the bonding of the positive and negative data of the electrode plate. (4) Short drying time: Due to the high air volume circulating drying method, the drying time is shorter than the traditional vacuum oven, especially the drying time of the pole and core can be shortened by more than 10 hours. (5) Energy saving: The use of large-capacity dehumidification equipment, with a high dehumidification capacity above 50°C, allows the hot and dry air to be fully circulated, greatly reducing energy consumption, and energy saving by more than 60% compared with traditional vacuum ovens. (6) Emission reduction: The BDA drying system should not be vacuumed during the drying process to achieve zero pollution emissions. (7) Small footprint; compact structure, no other supporting equipment, and independent. (8) Long service life; high temperature moisture absorption equipment and heat recovery can be used continuously for 5-8 years, do not change the data. (9) The cleanliness of the supply air is high; the system is equipped with a high-efficiency filter, and the supply air cleanliness level can reach 10,000, which reduces the pollution of dust on the pole pieces and batteries, and greatly improves the quality of the pole pieces and batteries. (10) Simple operation: The BDA drying system is an organic whole, do not need to be equipped with auxiliary equipment such as vacuum pumps and nitrogen generators.
