LR1130 battery.Korean lithium battery dry hot air impact drying process

　　The process introduced this time is a new process that shock-evaporates and dries the moisture in the pole pieces, cells, and batteries before liquid injection to precipitate the moisture. It uses a super-capable moisture separation device. The entire impact evaporation drying and moisture precipitation process is carried out through a large circulation of dry air less than 5PPM and sent into the drying chamber of the oven to impact the pole pieces, cells and batteries before the battery is filled with liquid. The final moisture is separated out by the super-capable moisture separation device, and the pole pieces, cells and batteries to be dried are continuously impacted, evaporated and dried over and over again. The super-capacity moisture separation device continuously separates out moisture, and the dry and hot air is fully circulated. Use, greatly reducing heating energy consumption.

　　Specific advantages:

　　(1) Large capacity of the drying cavity: The drying capacity is large at one time, which is especially suitable for large-scale power batteries and large-scale battery production.

　　(2) The moisture content of dry air is low; the moisture content of dried dry air is below 5PPM, which is 190 PPM lower than the moisture content of commonly used 99.9% pure nitrogen. The moisture content is 5PPM lower than that of commonly used 99.99% pure nitrogen.

　　(3) Low drying temperature: The drying temperature is 15-20°C lower than that of traditional vacuum ovens. The shrinkage and deformation of the diaphragm is minimal, and it basically does not affect the adhesion of the positive and negative materials on the pole pieces.

　　(4) Short drying time: Due to the large air volume circulation drying method, the drying time is shorter than that of traditional vacuum ovens, especially the drying time of pole pieces and battery cells can be shortened by more than 10 hours.

　　(5) Energy saving: It adopts a super-capable moisture separation device, which has a high moisture separation capability above 50°C, allowing the dry and hot air to be fully recycled, greatly reducing energy consumption, and is more energy-saving than traditional vacuum ovens. More than 60%.

　　(6) Emission reduction: The BDA drying system does not require vacuuming during drying, achieving zero pollution emissions.

　　(7) It occupies a small area; the system has a compact structure and does not require other supporting equipment and is self-contained.

　　(8) Long service life; high-temperature moisture absorption capacity devices and heat recovery can generally be used continuously for 5-8 years without the need to replace materials.

　　(9) The air supply air has a high cleanliness level; the system is equipped with a high-efficiency filter, and the air supply air cleanliness level can reach 10,000 levels, which reduces the pollution of the pole pieces and battery cores by dust and greatly improves the efficiency of the pole pieces and battery cores. quality.

　　(10) Simple operation: Since the BDA drying system is self-contained, it does not need to be equipped with other auxiliary equipment such as vacuum pumps and nitrogen generators.
