     Lithium-ion power batteries are new high-energy batteries that have been successfully developed in the 20th century. In the 1970s, it became practical. Because of its high energy, high battery voltage, wide operating temperature range and long storage life, it has been widely used in military and civilian small appliances, such as mobile phones, portable computers, video cameras, cameras, etc., and partially replaces traditional batteries. Large-capacity lithium-ion batteries have been tested in electric vehicles and will become one of the main power sources for electric vehicles in the 21st century, and will be used in satellite, aerospace and energy storage.

With the development of microelectronics technology in the twentieth century, the number of miniaturized devices is increasing, and high requirements are placed on power supplies. Lithium-ion power batteries have entered the practical stage of large-scale production. However, the coater is very close in the cell process of the lithium ion power battery.

    The process of the coating machine: the pole piece substrate placed on the unwinding device is pulled out by the roller, and after automatically correcting, enters the floating roller tension system, adjusts the unwinding tension and enters the coating head, and the pole piece slurry is coated. The system's setup program is applied. The coated wet film enters the oven and is dried by hot air. The dried pole piece is tensioned by the tension system, and the winding speed is controlled to synchronize with the coating speed. The pole piece is automatically corrected by the correcting system to keep the substrate in the The center position is neatly wound by the winding device.

4. When the coating machine is running, the pole piece is broken.
1. The belt is not right, and the additional pulling force is increased to make the foil strip break in the weak place. 2. Sampling causes damage, resulting in a significant decrease in the tensile strength of the foil strip. 3. The tension is too large, unstable, and there is a sudden change. 4. The air volume is abrupt and the distribution is severely uneven.
5. The temperature is abrupt, which has a great influence on the strength of the aluminum foil. 6. The quality of the foil strip is poor and the edge is notched.
7. The foil strip is seriously deviated and is cut off by the edge of the roll end. V. Other failure phenomena:
1. There are obvious embossing marks and scratches on the pole piece, which are longitudinally distributed: 1) The blade of the scraper roller has a gap or sticks with foreign matter.
2) The coating roller is not easy to use. If the gap material on the coating roller is not scraped off and applied to the substrate again during the coating gap, it will leave obvious marks on the substrate;
3) The axis of the scraper device is out of line with the axis of the coating roller, causing the blade to be inconsistent with the pressure of the coating roller, the shape of the blade is not suitable, the blade elasticity is low, etc.
2. There are obvious cracks on the pole piece: the drying speed is too fast, the oven temperature is too high, and the baking time is too long.
