✅ Brief Introduction
Termination layer insulation tape is a single-sided pressure-sensitive adhesive tape widely used in the manufacturing stage of lithium battery cells, for covering the end region of the cell tab (i.e., the termination layer), providing stable electrical insulation, preventing short circuits, and being compatible with subsequent heat sealing and liquid injection processes. This tape features excellent electrical strength, resistance to electrolyte corrosion, and thermal stability, making it a key material for ensuring battery safety and consistency.

✅ Full Product Description
Termination Layer Insulation Tape Solutions
Providing professional adhesive solutions for the manufacturing of electric vehicle power batteries, the termination layer insulating tape is primarily applied in the encapsulation process of the electrode terminal area in the cell manufacturing process, ensuring electrical isolation and chemical compatibility between the negative/positive electrode terminals during hot pressing encapsulation and liquid injection processes.

This series of tapes uses high-temperature resistant polyester (PET) or polypropylene (PP) film as the substrate, coated with an electrolyte-compatible acrylic adhesive, offering excellent insulation performance and structural stability. The tape is self-adhesive and does not require a backing paper, facilitating automated winding operations and accommodating the process requirements of various power lithium batteries (prismatic, cylindrical, pouch).

Key Features and Benefits
✅ High dielectric strength: Effectively isolates voltage up to 5.0~6.5 kV AC, meeting the safety requirements of high-energy density batteries

✅ Good electrolyte compatibility: Special acrylic adhesive ensures long-term resistance to electrolyte immersion environment

✅ Chemical inertness: Polypropylene/polyester substrate suppresses DMT-type reduction shuttle effect, reducing self-discharge risk

✅ Green coloring adhesive: Facilitates automated visual inspection, improving process stability

✅ Bottomless paper structure: Self-wrapping form, enhances automated encapsulation efficiency, reducing material waste

✅ Supports multiple width and thickness specifications: Adaptable to different earphone structures and electrode layer counts

✅ Meets the manufacturing location requirements of the Inflation Reduction Act IRA (Made in USA, optional)
