Adhesive Tape Solutions for Lithium Battery Industry

[1] High temperature resistant tape

PI film or brown PET film is used as the base material, usually coated with high-performance acrylic pressure sensitive adhesive, which is used for high-temperature fixed bonding of lithium battery housing, as well as insulation protection of the inner electrodes and external tabs of the battery cell.

[2] Termination tape

PET (polyester) or PP (polypropylene) films are coated with a unique electrolyte-resistant acrylic or rubber pressure-sensitive adhesive. In addition, in order to facilitate the track and trace of the production line, the termination tape can be made into a digital tape, that is, Arabic numerals are printed on the film substrate before the pressure-sensitive adhesive is applied.

[3] Blue film tape

It is composed of a double-layer PET substrate coated with an acrylic adhesive layer, which plays the role of appearance protection and insulation in pack assembly. In addition to the excellent electrical and mechanical properties of the film, it also has stable and good adhesion properties. The double-layer composite substrate is soft, bending and sticking without warping, leaving no residual glue, and at the same time, it also makes the product have a bright color like printing.

[4] Process protective film

The protective film is made of transparent PET or BOPP film after corona treatment, coated with special pressure-sensitive adhesive with different color pastes, and processed after hot air baking. Good light transmittance, excellent stiffness, easy die-cutting, no glue residue. Protects the appearance of the battery cell during the cell assembly process.

[5] Flame retardant double-sided tape

It is mainly used for the bonding of foam and other components.

[6] Hot-pressed insulating film for side panels

It is a single-sided hot-melt tape that is hot-pressed and laminated to the inside of the battery pack to insulate the battery and the outer shell.

[7] Thermal pads, etc

Thermal interface materials, thermal pads fill the air gap between the heat-generating device and the heat sink or metal base, and their flexible, elastic characteristics allow them to be used to cover very uneven surfaces. Heat is conducted from the discrete device or the entire PCB to the metal enclosure or diffusion plate, increasing the efficiency and lifetime of the heat-generating electronic assembly.

[8] Expansion tape

Using OPS resin film as the base material, coated with anti-electrolytic hydraulic sensitive glue, after the cell enters the shell, the film has about 150-200% expansion in the high temperature and electrolyte environment, filling the gap between the inner cell and the shell to prevent vibration, mainly used in the power tool industry with vibration. The full English name of OPS is Oriented Polystyrene Films, which means oriented polystyrene film in Chinese.

[9] Aluminum-plastic film

Aluminum-plastic film is also a plastic film product. The core material of pouch cells.
