Lithium battery dry hot air impact drying treatment process

Introduced the new technology of shock wave transpiration drying and dehydration before lithium battery electrode, battery core, and battery injection. Adopt super large capacity dehumidifier. Shock wave transpiration drying, the water cycle process is to send the separated dry air less than 5ppm into the oven drying room for processing. After the shock wave transpiration water before the battery and battery injection is dried, the shock wave transpiration and ultra-wet separation capacity analysis equipment, drying cycle Continuous processing of pole pieces, batteries, batteries, and liquid jets before drying are oscillated and transpired. The analysis capability of strong humidity equipment can continuously separate water and dry air and recycle them, which greatly reduces heating energy consumption.

detailed advantages:

(1) Large drying chamber capacity: large drying capacity, especially suitable for the production of high-power batteries and large batteries.

(2) Low moisture content of dry air: The moisture content of dry air is less than 5PPM, which is 1900ppm and 99.9% lower than pure nitrogen. The water content of nitrogen is 5PPM, and the purity is less than 99.99%.

(3) Low drying temperature: The drying temperature is 15-20℃ lower than that of the traditional vacuum oven, the gap is shortened and the deformation is minimal, and it has no effect on the bonding of the positive and negative data of the sheet.

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

(5) Energy saving: Using large-capacity dehumidification equipment, the dehumidification capacity above 50℃ is very high, so that the hot and dry air can be fully circulated, greatly reducing energy consumption, and saving more than 60% of energy compared with traditional vacuum ovens.

(6) Emission reduction: The BDA drying system does not have a vacuum during the drying process to achieve zero pollution emissions.

(7) Small footprint, compact structure, no other supporting equipment, complete equipment.

(8) Long service life; high temperature moisture absorption equipment and heat recovery can be used for 5-8 years without changing the data.

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

(10) Simple operation: The BDA drying system is an organic whole, without auxiliary equipment such as vacuum pumps and nitrogen generators.
