The characteristics of lithium battery tape, retaining wall tape manufacturers to explain for you

Retaining wall tapeThe manufacturer thinksLithium battery tape refers to the intermediate production process of lithium battery cells.Pressure-sensitive adhesive tape for electrode winding, pole piece protection and winding core termination in (winding/lamination, shell welding and sealing, etc.). Its main function is to insulate and fix the lithium battery. The development of lithium battery tape is accompanied by the development of lithium batteries.

Retaining wall tape manufacturers believe that lithium battery tape is a pressure-sensitive tape with special functional characteristics, with a certain initial viscosity, continuous viscosity, temperature resistance and chemical resistance. Reusable, environmentally friendly, and environmentally friendly to the surface of the adherend after peeling. Lithium battery tape is used in different parts of lithium batteries, with different efficacy requirements, different performance standards, and different production companies. In order to meet the needs of customers and the market, it is divided into different lithium battery tapes with different characteristics. China's lithium battery tape production enterprises are uneven, the level of technology research and development is relatively backward, lack of core technology, most of them are in the processing and production stage.

The characteristics of lithium battery tape are mainly determined by the substrate, adhesive, use and other factors, so lithium battery tape is generally classified according to the substrate, adhesive, and use. There are many kinds of lithium battery tape. Manufacturers are mostly based on customer requirements to develop and produce lithium battery tape. Among them, the composition of the adhesive determines the characteristics and uses of the lithium battery tape. Commonly used adhesives are acrylate adhesives and rubber adhesives.

Retaining wall tape manufacturers believe that lithium battery tapes prepared by different adhesives have different characteristics: acrylate lithium battery tapes prepared by acrylate adhesives have good aging resistance and weather resistance, high temperature resistance and good thermal stability, good adhesion to polar surfaces, low adhesion to non-polar surfaces, and low initial peel strength. The rubber lithium battery tape prepared with rubber adhesive has high shear resistance at high temperature and can be pasted on various surfaces with good initial adhesion, but poor aging resistance and solvent resistance.

Retaining wall tape manufacturers believe that different lithium battery manufacturers use different lithium battery tapes due to different battery types, models, and production equipment. In summary, the preparation and application process of lithium battery tape is roughly as follows:

1. Substrate treatment: Corona treatment of PP, PET and PI film substrates to obtain rough and smooth film substrates, or coating release agents on non-adhesive surfaces to obtain release films, or adding a layer of digital ink to obtain digital films;

2. Coating glue, coating pressure-sensitive glue on the corona surface of the treated film, and drying and curing the glue through the high-temperature baking channel;

3. Rolling, equipment cooling, rolling into semi-finished products according to specifications;

4. Cutting. The manufacturer of the retaining wall adhesive tape thinks that when the semi-finished product is rolled up, the harvested master roll needs to be re-rolled and then cut or divided to obtain the finished product (when the semi-finished product is rolled up, only small rolls or divided to obtain the finished product can be directly cut), and the finished product can be packaged and sold.

Retaining wall tape manufacturers believe that the equipment used to process tape includes tape coating machines, fine rewinding machines, fine slitting machines and fine slitting machines. In order to ensure that the tape is not contaminated during the production process, especially not contaminated by magnetic materials, all processes must be completed in a clean area above 10000.
