Today, lithium battery measurement has become more and more important in the production of lithium batteryproducts, because in mass-produced manufacturers, if a little error occurs in the product, the product will be scrapped. This is why the measurement of lithium battery becomes more and more serious. The more important it is, what are the lithium battery testing equipment commonly used in the production of products ? Let’s take a look today.

　　1. Laser thickness gauge (coating type/rolling type)

　　typical application:

　　Thickness measurement of lithium battery cathode and anode coating and rolling.

　　The coating type laser thickness gauge can be placed behind the coating head and in front of the oven to measure the thickness of the coated wet film; it can also be placed after the oven and before the winding to measure the thickness of the dry pole piece; roll pressure type laser thickness gauge Place it after the pressing roll and before winding, and measure the thickness of the pole piece after pressing.

　　Highlights:

　　1) Marble C frame and guide shaft base, no stress, to ensure long-term stability;

　　2) Coaxiality adjustment device for upper and lower laser optical paths (Patented by Dacheng);

　　3) Coating type laser thickness gauge: thickness profile measurement function of the edge thinning area; (unique)

　　4) Roller-type laser thickness gauge: Supported by a small supporting roller to reduce the tilt angle of the pole piece caused by uneven tension of the pole piece;

　　5) Roller type laser thickness gauge: composite material multilayer vibration isolation design, completely isolate all vibration interference sources; (unique)

　　2. X/β-ray areal density measuring instrument

　　typical application:

　　Lithium battery cathode and anode coating, lithium battery separator coating, paper areal density measurement.

　　When used in the coating process of lithium batteries, the equipment can be placed in the coating machine after unwinding and in front of the coating head to measure the areal density of the substrate to be coated;

　　It can also be placed outside the oven, before winding, to measure the surface density of the dried pole piece.

　　Product Highlights:

　　1) Marble O-frame structure to ensure long-term stability without deformation;

　　2) Compared with domestic equipment, the maximum scanning speed can reach 25m/min;

　　3) Radiation shielding effect<1uSv/h;

　　4) Imported high-precision ionization chamber: measurement accuracy is as high as ±0.25‰;

　　5) It can form a closed loop control with the coating machine.
