     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.

In the coating process, the coating gap is poor and the pole piece wrinkles are analyzed:

I. The phenomenon and cause of poor coating gap
1. Trailing
(1) Material: slurry material, viscosity, solid content, slurry (surface) tension
(2) Equipment: coating-back roller distance. speed of coating roller when back roller is opened. diameter of back roller. back roller surface material. back roller deformation. back roller and coating roller parallelism. back roller and oven front Rolls are not parallel. Tension in operation
(3) Operational aspects: parameters for head and tail adjustment 2. Head and tail are not parallel
(1) Material: the gravitational pull on both sides of the substrate
(2) Equipment: The back roller and the coating roller are not parallel. The back roller is not open when it is opened. The back roller surface is coaxial. The back roller and the traction roller are not parallel. The level changes. (3) The tension roller adjustment state.
