High-Quality Lithium Battery Tabs - Nickel/Aluminum/Copper-Plated/Al-Ni Transition for Li-Ion Flexible Batteries
Product Overview
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.
Features:
- Superior electrolyte resistance: Maintains stable performance after long-term contact with electrolytes, avoiding corrosion-induced degradation.
- Strong sealing: Isolates battery internals from the outside, blocking moisture/dust and preventing electrolyte leakage.
- Wide size range: Covers various sizes to match different lithium-polymer battery needs.
- Diverse thickness options: Offers multiple thicknesses for flexible application in devices like phones or laptops.
- Rich material combinations: Provides varied material pairings, eliminating custom processing and boosting procurement efficiency.
