     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.

PET film--

 

(3) PET reflective film
PET reflective film is characterized by excellent optical properties, smooth surface, smooth surface, good thermal stability, low shrinkage and light aging resistance.
Reflective materials used in transportation facilities include lens-type retroreflective film and flat-top reflective film. They are all made of aluminized PET film as a reflective layer. After applying pressure sensitive adhesive, some glasses with a refractive index of 1.9 are used. The beads are adhered to the PET aluminized film, and then a layer of butyral surface protective layer is sprayed.
PET reflective film is applied to billboards with reflective requirements, traffic reflective signs (reflective road signs, reflective barriers, reflective number plates), reflective police uniforms, industrial safety signs, etc.

(4) Chemical coating film
Polyester film In order to improve the surface properties of the PET film, in order to improve the adaptability of printing and the bonding force of the vacuum aluminum plating layer, a corona treatment method is generally used to increase the surface tension of the film. However, the corona method has problems such as aging, and particularly in a high-temperature, high-humidity environment, the film tension after corona treatment is easily attenuated. However, the chemical coating method does not have such a problem, so it is favored by the printing industry and the aluminum plating industry. Jiangsu Zhongda has developed a series of PET chemical coating products: coating with water-soluble polymer can improve the surface tension of PET film; coating with acrylate emulsion can improve printing adaptability (water-soluble ink can be used) The coating with polyurethane aqueous solution can strengthen the bonding force between the aluminum plating layer and the PET base film, and can increase the thickness of the aluminum plating layer.
In addition, a high-resistance film, an antistatic film, and the like can be obtained by a coating method.
