LithiumBattery TapeWhat types are there? How to choose?

Lithium battery tape and lithium battery protective film tape are used to treat various substrates with various glues, primers, and release agents to make them have different characteristics to meet various needs. According to different needs, lithium battery tape can be divided into the following types:

Lithium battery tape is divided into polyester and polyimide according to the substrate.

Lithium battery tape according to the adhesive system is divided into: acrylic series, silicone pressure sensitive adhesive series, rubber pressure sensitive adhesive series.

Lithium battery tape is classified by use: terminal tape, packaging tape, protective film tape, high temperature tape, fixing tape, detachable tape, double-sided tape, etc.

lithium battery tape application:

1. Battery (digital) terminal belt

Battery tape for cylindrical, square, small and medium-sized lithium electronic batteries, high-power lithium electronic batteries and other battery ear position and winding position of the terminal insulation and fixed. To prevent and prevent the role of puncture.

2. Packaging high temperature tape

Battery tape for lithium battery steel shell, aluminum shell, cylinder, flexible battery, power battery component core edge sealing, bottom insulation protection, binding and fixing.

3. Lug tape

Lithium battery terminals, such as steel shell, aluminum shell, soft package, cylinder, etc. Wrap the solder joint of ultrasonic welding to prevent the solder joint from piercing the diaphragm and causing the core short circuit; High temperature resistance and electrolyte corrosion resistance; Prevent the internal resistance of the battery from increasing.

4. Polyester film

Battery tape is used to stick black, red and blue glues on the top and bottom of cylindrical batteries, and is used for packaging in various battery pack processes.

5. Fiber tape

The unique pressure-sensitive adhesive layer has excellent long-lasting adhesion and special properties, excellent alkali resistance, high tensile strength and deformation resistance, excellent self-adhesion, insulation and thermal conductivity, and high temperature resistance. Bundle protection for small power batteries.

6. Masking paper tape

The battery tape is mainly used to seal the top edge of the battery cell during the injection molding process, and has good adhesion and high temperature resistance.

There are many types of tapes introduced by lithium battery tape suppliers, so the performance and strength of different brands of tapes are different, so the following factors should be considered when purchasing tapes:

Microporosity of the adherend: due to the adhesive effect of the tape, the moisture of the adhesive on the surface of the tape penetrates into the adhesive, and dries quickly after the tape is pasted, making the tape a part of the adhesive. Therefore, the microporosity of the surface of the adhered object is very important for the selection of the tape. If the microporous product is more hygroscopic, it is necessary to use the tape with faster condensation; otherwise, it is necessary to use the tape with slower condensation speed or the tape with more adhesive.

Adhesive on tape surface: LithiumBattery TapeThe supplier's bottom tape is coated with adhesive. Usually, after it is sufficiently dried, it is finished into a roll. If the tape is too wet, the tape itself will stick tightly together, it is difficult to open when using, and some are not used at all.
