Application of Vacuum Drying Oven in Lithium Battery Production

Vacuum oven, also known as vacuum drying oven, are widely used in chemical, electronic, food, light industry, medicine, etc. They can dry materials under vacuum condition. The utility model has the advantages of fast drying speed, small pollution, and no damage to the internal quality of dry articles.

The vacuum drying oven is specially designed for the baking process of lithium ion batteries. Due to the particularity of the oven materials, the special oven for lithium batteries needs to be resistant to strong acid and alkali corrosion, temperature control, program control efficiency, stability and other characteristics

Equipment working principle

The boiling point of battery vacuum oven decreases with the decline of air pressure. The boiling point of water decreases significantly under negative pressure. When the air pressure drops to -0.089Mpa, the theoretical boiling point can be reduced to 45 ℃. Under negative pressure environment, water is easier to gasify.

After being heated for a period of time in the special lithium battery oven under normal pressure, the water in the battery or electrode plate is converted into water vapor; The water vapor can be extracted by vacuuming after water evaporation; Fill nitrogen to break the vacuum and keep the dry environment. In the actual baking process, according to different processes, the above three steps are different in sequence, which generally require multiple cycles.
