In today's lithium battery production, in order to ensure the final production quality of lithium battery, we usually use a variety of professional measuring instruments to measure the size and specification of lithium battery, so as to ensure the final specification and standard degree of lithium battery. At this time, we need to use lithium battery testing equipment.

Lithium battery testing equipment plays an important role in the manufacture of high consistency, good stability and excellent performance of lithium cell and battery pack.

By monitoring and tracing the lithium battery testing equipment from time to time, we can understand the dynamic of the production line at any time, and quickly find out the cause of the problem products, so as to improve the production efficiency, improve the yield of products, and improve the overall performance of products. Next, let's introduce the lithium battery testing equipment developed by ruijiada

1. X-ray areal density meter

Typical applications

Surface density or thickness measurement of lithium battery cathode coating, lithium battery isolation film coating and papermaking. When applied in the lithium coating process, the equipment can be placed in the coater after unwinding and before coating to measure the area density of the substrate to be coated; it can also be placed outside the oven and before winding to measure the area density of the drying electrode.

measuring principle 

The non-destructive and non-contact measurement of the area density of thin film materials is realized by using the absorption and back scattering effects of X-ray penetrating materials.

2. Beta ray areal density meter

Typical applications

Surface density or thickness measurement of coating and papermaking for positive and negative electrodes of lithium batteries. When applied in the lithium coating process, the equipment can be placed in the coater after unwinding and before coating to measure the area density of the substrate to be coated; it can also be placed outside the oven and before winding to measure the area density of the drying electrode.

measuring principle 

The non-destructive and non-contact measurement of the area density of thin film materials is realized by using the absorption and backscattering effects of β - ray penetrating materials.

3. Multi frame ray synchronous tracking measurement system

Typical applications

The surface density measurement of positive and negative coating amount of lithium battery. When it is applied in lithium coating process, the former is placed after unwinding and before coating to measure the surface density of the substrate or one side, and the latter is placed outside the oven and before winding. The drying electrode is tracked at the same point along the measurement track of the former, and then the surface density of the former is subtracted from the surface density of the latter to obtain the surface density of the net coating amount.

If it is a double-layer coater, you can use three synchronous tracking measurement system. The first frame is used to measure the substrate, the second frame is used to measure the single-sided pole piece with the same track, and the third frame is used to measure the double-sided pole piece with the same track. Finally, the single-sided net coating amount and double-sided net coating amount are calculated.

measuring principle 

Several scanning frames are used to track and measure the film materials in coating process synchronously, and the area density of net coating amount is obtained.
