During the production process of a lithium battery separator, a drying equipment is needed to process it to meet the quality requirements for the use of the separator. The thickness of a lithium battery separator is usually between 10 and 30 microns. The thinner the separator, the higher the battery energy density and the higher the stability. The thickness of the separator directly affects the overall performance of the battery.

Material rollers are arranged on both sides of the box body. A separator main body passes through the box body between the material rollers. A drying plate is arranged inside the box body. An air outlet is arranged on one side of the drying plate close to the separator main body. A blower is arranged on the side of the drying plate far from the separator main body. An electric heating box is arranged on one side of the blower. A ventilation pipe is arranged on one side of the electric heating box. Sliders are arranged at both ends of the drying plate. Chute grooves are arranged on the inner walls of both sides of the box body;
[0004] Although this double-sided drying device for lithium battery separators adjusts the distance between the drying plate and the separator main body by making two groups of drying plates move in opposite directions, which is convenient for targeted drying of different drying conditions required by different separator main bodies, the separator of this double-sided drying device for lithium battery separators passes horizontally through the box body. Due to its own gravity, the separator will bend downward, resulting in uneven heating on both sides of the separator.
