Mara tape manufacturers: classification of battery tape

The characteristics of the battery tape are mainly determined by the substrate, the adhesive and the use, so the battery tape is generally classified by the substrate, the adhesive and the use. battery glue with many kinds. The composition of the adhesive determines the characteristics and uses of the lithium battery tape. BelowMarla tape manufacturersto introduce you to the classification of battery tape.

1. Ultra-thin lithium battery terminal tape

Mara tape manufacturer: With the miniaturization of various electronic devices, the market has higher and higher requirements for the size and thickness of batteries, and the thickness of lithium battery materials is getting thinner and thinner.

2. Lithium battery digital terminal belt

Mara tape manufacturer: The market has put forward requirements for controllability and traceability of product quality. The lithium battery digital terminal belt is another lithium battery terminal belt developed to meet the needs of the market. It is to add printed digital labels to the lithium battery terminal belt, and its performance requirements are consistent with the lithium battery terminal belt. Digital adhesive tape is usually composed of adhesive layer, protective layer, ink layer, primer, substrate and release layer adhesive tape structure. Biaxially stretched PET or PP film is used as the substrate, printing ink is used as the digital functional layer, and one-component silicon-free release agent is coated on the non-digital surface of the substrate as the unroll coating. Acrylic adhesive layer is coated on the digital surface of the substrate to prepare digital adhesive tape for lithium battery.

3. High temperature resistant tape for lithium battery

Mara Tape Manufacturer: Lithium battery high temperature resistant tape is a battery tape developed to ensure that lithium ion batteries have good stability in production and use. Under high temperature conditions, lithium batteries can maintain stable structure in high temperature environment, and their chemical properties remain unchanged for a long time to ensure that lithium batteries do not have short circuit, leakage and liquid leakage characteristics in high temperature environment. The original high temperature resistant tape for lithium batteries is silicone tape, but in recent years, the lithium battery industry has proposed that the battery cannot contain silicon elements, so most of the high temperature resistant tapes on the market are acrylic battery tapes.

4. Lithium battery ear patch

Mara tape manufacturer: when making lithium batteries, it is necessary to weld the tabs to extend the tabs and facilitate the next process to melt the sealant for sealing in the top edge sealing process. Ultrasonic welding is used for pin welding, and spot welding spots will appear at the lug after welding. Because the lug protruding height position may not meet the requirements. In general, the need to bend the polar ear. In this case, it is easy to produce a short circuit, so it is necessary to paste the insulating tape at the welding position, and the insulating tape needs to be pasted on both sides of the tab.

5. Lithium battery double-layer protective tape

Mara tape manufacturer: lithium battery shell is hard and transparent, the lithium battery tape required to protect the edge of the package is soft, sticky, good adhesion, and does not warp for a long time. This tape is called lithium battery double-layer protective tape.

6. Power battery tape

　　Marla tape manufacturers: The power battery adhesive tape is based on PET film, coated on the PET film is a pressure-sensitive adhesive (acrylate rubber glue or glue), used for electric vehicles, flexible packaging battery shell, set inside the battery shell, covering the top of the sealed shell, battery top, two sides and bottom parts maintenance fixed battery insulation adhesive tape.
