Description

Technical Field

[0001] The utility model belongs to the technical field of lithium battery diaphragm production, and in particular relates to an oil mist removal device installed on a lithium battery diaphragm wire die head. Background Art

[0002] In the structure of lithium batteries, the diaphragm is one of the key inner components. The performance of the diaphragm determines the interface structure and internal resistance of the battery, and directly affects the battery's capacity, cycle and safety performance. A diaphragm with excellent performance plays an important role in improving the overall performance of the battery. The materials of lithium battery diaphragms are mostly polyolefin materials, such as polypropylene (PP) or polyethylene (PE). Pore formers and a small amount of additives must be added during the film making process. During the heating of the material, a small amount of oligomers in the plastic will evaporate, and pore formers and a small amount of additives will also precipitate. These evaporated oil mists will turn into white powder when cooled. If these white powders adhere to the battery diaphragm, it will cause a short circuit in the battery, posing a safety hazard, so the oil mist needs to be removed.

[0003] A die is required for the production of lithium battery diaphragms. The most oil mist is found at the die casting part, i.e., at the die lip outlet. On the side of the die close to the vacuum patch, the oil mist is sucked away by the vacuum patch. On the other side of the vacuum patch, a small amount of oil mist will adhere to the die lip. The oil mist on the outside will turn into white powder when it is cooled. When the white powder reaches a certain amount, it will fall onto the diaphragm. If it is not cleaned in time, a large amount of waste will be generated, which will seriously affect normal production. Most of the existing technologies use sponge wiping and negative pressure adsorption to remove oil mist. However, after some negative pressure adsorption equipment is connected to the die, the angle of the negative pressure adsorption equipment cannot be adjusted, and its use has certain limitations.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
