Production Process 2- Coating

Uninterruptible Power Supply (UPS) is an important equipment in modern power management, and its stability and reliability directly affect the power safety of users. The production process of UPS includes a number of key links, and the coating link plays a crucial role in them. This paper will discuss the coating process of UPS production process in depth.

main content

Unwinding

The coating process begins with the unwinding of the substrate (such as copper foil or aluminum foil), which is the first step in the coater. The substrate is released from the unwinding device and enters the coater.

Splicing

The end and end of the substrate are connected into continuous strips at the splicing table to ensure the continuity of the coating process.

Tension control and automatic correction

During the coating process, tension control and automatic correction are two important auxiliary means to ensure the tension stability and accurate position of the substrate during the coating process.

Coating

The polar sheet stock is coated in the coating device according to the predetermined coating amount and blank length. The coating method and parameters have a direct effect on the battery performance.

Drying

The coated wet pole sheet is sent to the drying channel for drying, and the drying temperature is set according to the coating speed and coating thickness. The purpose of drying is to remove solvents and moisture, so that the active substance in the electrode sheet solidifies.

Tension control and automatic correction

After drying, the pole sheet is again subjected to tension control and automatic correction to ensure the quality of the pole sheet.

Winding

After drying and forming, the pole sheet is rewound for the next step.

Critical control points

After drying and forming, the pole sheet is rewound for the next step.

Coating drying temperature control

Too low drying temperature during coating may lead to incomplete drying of the pole sheet, while too high temperature may lead to cracking and falling off of the surface coating of the pole sheet.

Coating surface density

The size of the coating surface density directly affects the battery capacity, too small may lead to the battery capacity is not up to standard, too large may cause material waste and safety risks.

Error correction accuracy

Error correction accuracy affects the uniformity and consistency of the coating, which in turn affects the battery performance.

Drying temperature

Drying temperature has a direct impact on the drying effect of the pole plate and the performance of the battery.

CONCLUSION

The coating process is a key step in the manufacture of lithium batteries, which plays a decisive role in the performance and safety of batteries. By precisely controlling the coating parameters, the quality and performance of the electrode sheet can be ensured, thus creating a lithium battery with reliable performance.
