What testing equipment is important for lithium-ion battery packs?

1. X/β-ray areal density measuring instrument: When used in the coating process of lithium-ion batteries, this equipment can be arranged after unwinding of the coater and in front of the coating head to measure the areal density of the substrate to be coated; Place it outside the oven, before rewinding, and measure the extremely unilateral density that has been dried. Product highlights: 1) The marble O-frame layout guarantees constant and stable shape; 2) Compared with domestic equipment, the maximum scanning speed can reach 25m/min; 3) Radiation shielding results <1uSv/h; 4) Entrance high-precision ionization chamber ：Measurement accuracy is as high as ±0.25‰; 5) It can form a closed-loop system with the coating machine; 2. Laser thickness gauge (coating type/roller type: coating type laser thickness gauge can be arranged behind the coating head and in front of the oven , To measure the thickness of the coated wet film; it can also be arranged after the oven and before rewinding to measure the thickness of the dry pole piece; the roller pressure type laser thickness gauge is arranged after the pressing roller and before the rewinding to measure the pressed pole piece Thickness. Highlights of the product: 1) Marble C frame and guide shaft base, without stress, guarantee permanent invariability; 2) Coaxiality adjustment device for upper and lower laser optical paths (Patented by Dacheng); 3) Coated laser thickness gauge: edge Surface measurement results of the thickness of the thinned area; (exclusive) 4) Roller-type laser thickness gauge: Supported by a small supporting roller to eliminate the inclination angle of the pole piece caused by uneven pole piece tension; 5) Roller-type laser thickness gauge: Multi-layer vibration isolation design of composite materials, completely away from all vibration nuisance sources; 3. Multi-frame synchronous tracking system: When applied to the lithium battery coating process, the previous one is arranged after the unwinding of the coating machine and in front of the coating head. The surface density of the substrate may be measured on a single side. The latter rack is arranged outside the oven and before rewinding. The drying pole piece is synchronously tracked and measured along the measurement track of the previous rack, and then the surface density of the latter rack is used to subtract The areal density of the previous frame is the areal density of the net coating amount.
