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

Retaining wall tape manufacturers believe that the substrateIt is the carrier of lithium battery tape, which affects the temperature range, tensile strength, shear strength and material cost of lithium battery tape. Common substrates areBOPP (biaxially oriented polypropylene), PET (high temperature resistant polyester film), PI (polyimide film), nomex (meta-aramid or aramid 1313) paper, etc. Polymer film has become a commonly used carrier substrate for lithium battery tapes due to its advantages of dimensional stability, high elasticity, good insulation, good acid and alkali resistance, good tear strength, and plasticizer resistance.

Wall tape manufacturers believe that different substrates give lithium battery tape different characteristics, the temperature resistance of the substrate determines the use of lithium battery tape temperature and temperature resistance of the upper limit. The PI substrate is larger than the PET substrate and the BOPP substrate, and the temperature resistance of the PI substrate is relatively good, while the temperature resistance of the BOPP substrate is relatively poor. The cost of the substrate is the opposite of the temperature resistance. The cost of BOPP lithium battery tape is lower than PI lithium battery tape.

Retaining wall tape manufacturers believe that with the development of new materials, the lithium battery tape industry has introduced some new adhesives, such as single-sided hot-melt lithium battery tape, double-sided hot-melt tape for lithium batteries, etc. In the patent of "single-sided adhesive tape for lithium battery and its preparation method", the structure, preparation method and application process of single-sided hot-melt adhesive tape for lithium battery are introduced in detail, and the basic characteristics of this kind of adhesive tape for lithium battery are expounded.

Retaining wall tape manufacturers believe that single-sided hot-melt tape for lithium batteries consists of a sealed hot-melt pressure-sensitive adhesive layer and a base film layer. The single-sided adhesive tape has good adhesion, can resist the corrosion of the lithium battery electrolyte, and does not chemically react with the electrolyte in the lithium battery, thereby maintaining the performance of the lithium battery. The lithium battery pack with single-sided hot-melt lithium battery belt is firmly bonded to the outer packaging material, has no relative displacement, good fall resistance, high safety, long service life and stable quality.

Lithium battery double-sided tape has a sticky side, usually acrylate glue; the other side is not sticky at room temperature, sticky when heated, usually hot melt adhesive. In use, one side of the tape has adhesion to aluminum foil and polyethylene film at room temperature, and the other side has adhesion to polypropylene surface above 80, which is more suitable for the production process requirements of lithium batteries.

Retaining wall tape manufacturers believe that the termination tape for lithium batteries refers to the pressure-sensitive tape used for electrode winding and core winding termination during the mid-term winding/stacking process of lithium battery cells. The tape has special requirements for substrate selection, adhesion, temperature resistance, electrolyte resistance, etc. In addition to the performance of the general pressure-sensitive adhesive tape, it is also a special pressure-sensitive adhesive product. Lithium battery termination tape is a pressure-sensitive adhesive tape widely used in batteries.

The above is about the battery tape in some knowledge points, I hope you can seriously learn to understand the relevant knowledge.
