Description

Technical Field

[0001] The invention relates to the technical field of battery drying equipment, and in particular to a working method of drying equipment. Background Art

[0002] In recent years, the trend of battery use in my country has become more and more obvious. With the continuous increase in the new energy industry, the efficiency of lithium battery use will be further promoted. However, moisture will have a great impact on the performance of lithium-ion batteries. More importantly, the moisture content of the battery will have a great impact on the safety and consistent performance of the battery. During the drying operation of lithium batteries, in order to reduce the boiling point of water, the battery will be placed in a vacuum environment and heated at the same time to fully discharge the moisture inside the battery. In the prior art, the battery drying process mostly adopts a single heat radiation transfer method. The entire drying cavity is heated by a heating wire, etc., and the material to be dried is placed in the heating cavity with a tray to heat it to dry it. However, the energy utilization rate is low during the drying process, and it is easy to cause uneven heating of the battery, which affects the quality, cycle performance and safety of the battery.

[0003] The Chinese patent application number is CN202110857758.7, and the publication date is 2021.10.01. It discloses a drying device, which relates to the technical field of battery manufacturing equipment. The drying equipment includes a drying box, a moving assembly, a loading and unloading component, and a feeding assembly; the drying box is provided with a accommodating cavity and an opening, and the opening is arranged on the side of the drying box and is connected to the accommodating cavity; a plurality of openings are arranged along the first horizontal direction and the vertical direction; the push-pull mechanism and the overhead crane mechanism are both arranged in the moving mechanism; the push-pull mechanism is used to move the sliding frame between the first position and the second position; the overhead crane mechanism is used to clamp the battery and load and unload the fixture; wherein, when the fixture is in the first position, the sliding frame is located in the accommodating cavity, and the panel is arranged at the opening and covers the opening; when the fixture is in the second position, the sliding frame is located outside the accommodating cavity, and the fixture is located below the overhead crane mechanism. The drying oven can bake the batteries of multiple clamps in the accommodating cavity and control the water content of the batteries, which not only reduces the difficulty of moving the clamps, but also reduces the cost of the clamps; however, this structure is for baking the batteries of multiple clamps, and cannot be controlled in a single way, and can only achieve horizontal pushing and pulling. When it is necessary to take out items in the cavity and the items can only be taken out in the vertical direction, the door panel pulled out in the horizontal direction will make the opening large enough, making it impossible to conveniently retrieve the items. At the same time, if the drawer needs to be opened conveniently, the drawer opening needs to be opened to the maximum, which will affect the air pressure in the box, and the structural reliability is not high.
