1. Storage requirements: In an environment with a temperature of 25±5°C and a humidity of no more than 50%, the aluminum foil must be protected from corrosion by air and water vapor during transportation;
2. This product is divided into two types, A and B. The key features of each are: the appearance of the A type is black, and the conventional coating thickness is 4~8μm on both sides, and the conductivity is more prominent; the appearance of the B type is light gray, conventional The coating thickness is 2~3μm on both sides, and the coating area can be welded with fewer layers, and the coating machine can identify the jump gap;
3. Type B (gray) carbon-coated aluminum foil can be directly ultrasonically welded in the coating area. It is only suitable for welding lugs of wound batteries (up to 2-3 layers of pole pieces), but the ultrasonic power and time need to be fine-tuned;
4. The heat dissipation of the carbon layer is worse than that of aluminum foil, so it is necessary to fine-tune the belt speed and baking temperature when coating;
5. This product has a considerable improvement in the overall performance of lithium batteries and capacitors, but it cannot be used as the main factor that changes certain aspects of the battery's performance, such as battery energy density, high and low temperature performance, high voltage, and so on.
