Durable Nickel/Aluminum/Copper-Plated/Al-Ni Battery Tabs - Suitable for Soft-Pack Flexible Lithium-Ion Batteries

Product Overview

Tabs are key raw materials for lithium-ion polymer batteries (e.g., mobile, Bluetooth, laptop batteries). As metal conductors, they draw positive/negative electrodes from battery cores (inner connections, not external copper sheets).

Made of adhesive film + metal strip (Al for positive, Ni/Ni-Cu for negative), the film insulates to avoid short circuits and bonds with aluminum-plastic film via ~140°C heat-sealing to prevent leakage. Common black film has 3 layers (melanin, PE, PP) with specific melting points.

Key Features

• Superior Electrolyte Resistance: It exhibits strong resistance to electrolytes, maintaining stable performance even when in long-term contact with battery electrolytes. This effectively prevents material degradation or functional failure caused by electrolyte corrosion, ensuring the reliability of the entire battery system.
• Excellent Sealing Performance: It features robust sealing capabilities, which can tightly isolate the internal components of the battery from the external environment. This not only blocks the entry of moisture, dust, and other impurities but also prevents the leakage of electrolytes, safeguarding the battery's safe operation and service life.
• Comprehensive Specifications: It covers a complete range of specifications, including various sizes, thicknesses, and material combinations. This wide selection can fully meet the diverse application needs of different types of lithium-ion polymer batteries (such as mobile phone batteries, Bluetooth batteries, and laptop batteries), eliminating the need for custom processing and improving procurement efficiency.

Technical Specifications

The white adhesive has a three-layer structure, with a surface layer melting point of 136~138°C and a middle layer melting point of 165°C.

Application Scope

Tab is a raw material for lithium-ion polymer battery products. For example, mobile phone batteries, Bluetooth batteries, laptop batteries, etc. used in our daily life all need tabs.
