Vacuum oven is specially designed for lithium battery industry production process of vacuum drying equipment, the temperature, vacuum degree, the size of the studio and the barrier height is maximally meet the needs of the lithium battery industry.
This vacuum oven is with Vacuum, pressure, pneumatic automatic programmable control, it is mainly used for Lithium battery materials and electrode sheet vacuum baking for Battery production line.
 
The working principle of the battery vacuum oven:
The battery vacuum oven is also a necessary processing equipment in the manufacture of lithium batteries. Unlike other battery testing equipment, the battery vacuum oven is used to remove water in the production of lithium batteries. The battery vacuum oven plays a considerable role. When the lithium battery is sealed, if the water content exceeds the standard, it may cause the battery to heat up or even explode. Therefore, the battery vacuum oven can remove water, so that the lithium battery can be used when it is used. More secure and efficient.
The battery vacuum oven is also called the battery vacuum oven. Its working principle is to use the characteristic that the boiling point of water is only 45 ºC at the pressure of -0.089Mpa to heat and remove water. The temperature does not affect the performance change of the lithium battery. Extract the water vapor and fill it with nitrogen. The water vapor will dissipate in the vacuum tube, and the water removal of the lithium battery is completed. After removing the water, the lithium battery can be safely packaged.
The temperature of the battery vacuum oven can not only be adjusted to 45 ° C. According to its function, the temperature can be adjusted between 20 ° C to 250 ° C, which can be required for different temperatures. Battery vacuum oven for battery water removal is a multi-cycle process, which requires waiting for a certain time.
When using a battery vacuum oven to remove water, in order to avoid the situation that the lithium battery is taken out and the next step of production will be impregnated with moisture, a three-box battery vacuum oven is generally used. The three-box battery vacuum oven is a door-to-door vacuum oven, which is generally three layers, and can be installed on the wall between the drying workshop and the liquid injection workshop. The drying workshop puts the materials into the oven. After the baking is completed, the materials can be taken out directly from the side of the injection workshop to inject the liquid. It improves the circulation efficiency, and more importantly, it avoids the possibility of moisture re-immersion in the process of removing the material from the vacuum oven and transporting it to another workshop.

What is the difference between a vacuum oven and a general oven?
Most industrial ovens have a temperature uniformity parameter: a natural convection oven is the upper limit of the operating temperature multiplied by 3%, and a forced convection oven is the upper limit of the operating temperature multiplied by 2.5%. But vacuum ovens do not have temperature uniformity parameters. why? The possibility of uniform temperature in the working room by the movement of gas molecules in the vacuum furnace has almost disappeared.
Vacuum ovens generally employ a method of first heating the wall surface of the vacuum chamber and then radiating the wall surface radiantly toward the workpiece. In this way, the temperature sensor of the temperature control instrument can be arranged on the outer wall of the vacuum. The sensor can accept convection, conduction and radiant heat simultaneously. The glass rod thermometer in the vacuum chamber can only accept radiant heat, and because the blackness of the glass rod cannot reach 1, a considerable part of the radiant heat is refracted, so the temperature value reflected by the glass rod thermometer must be lower than the temperature reading of the meter. .
Generally speaking, it is normal for the temperature reading of the meter and the reading of the glass rod thermometer to be within 30 ° C at 200 ° C. If the temperature sensor of the temperature control instrument is installed in the vacuum chamber, the difference can appropriately reduce the difference between the temperature value of the glass rod thermometer and the temperature reading of the instrument, but it cannot be eliminated, and the sealing reliability of the vacuum chamber increases the potential Unreliable contact. If you don't want to see this difference from a practical perspective, you can use the display correction feature unique to temperature-controlled instruments.
Therefore, conceptually, we can no longer apply the definition of temperature uniformity specified by industrial ovens to vacuum ovens.
It does not make sense to set this indicator to a vacuum state. The amount of heat dissipation is inversely proportional to the square of the distance. For the same object, the radiant heat received at a distance of 20 cm from the heated wall is only 1/4 of the radiant heat received at a distance of 10 cm from the heated wall. Huge gap. This phenomenon is similar to the fact that when exposed to the sun in winter, the side exposed to the sun will be very warm, while the side exposed to the sun will be relatively cold.
