For lithium-polymer batteries in mobiles, Bluetooth gear, and laptops, tabs are indispensable raw materials. These metal conductors pull positive/negative electrodes from battery cores—note: they’re internal connections, not external copper sheets.

Structured as adhesive film + metal strip (positive: aluminum; negative: nickel/nickel-copper), the film insulates to avoid short circuits. It also bonds with aluminum-plastic film through ~140°C heat-sealing to block leakage. Typical black film includes 3 layers (melanin, PE, PP) with specific melting points.

1. Superior electrolyte resistance: Maintains stable performance after long-term contact with electrolytes, avoiding corrosion-induced degradation.
2. Strong sealing: Isolates battery internals from the outside, blocking moisture/dust and preventing electrolyte leakage.
3. Wide size range: Covers various sizes to match different lithium-polymer battery needs.
4. Diverse thickness options: Offers multiple thicknesses for flexible application in devices like phones or laptops.
5. Rich material combinations: Provides varied material pairings, eliminating custom processing and boosting procurement efficiency.

• Metal Coating Tech: Special surface treatment ensures strong bonding to Ni/Al/Cu.
• Electrolyte Resistance: PPA high-temperature barrier layer prevents HF corrosion.

• In-House Production: Rapid prototyping (<2 weeks) for custom shapes/sizes.
• Quality Control: Burr-free edges, ISO-compliant.
