8mm Wide Aluminum Battery Tab Customizable Size Polymer Battery Cathode Material

Product Overview

This high-purity aluminum battery tab serves as a critical current-collecting lead component engineered specifically for polymer lithium-ion and pouch cell positive electrode connections. Fabricated from 99.99% pure metallurgical-grade aluminum, the conductor strip delivers exceptional electrical conductivity, minimal internal ohmic resistance, and superior thermal dissipation under continuous charge and discharge cycles. The material provides a stable electrochemical interface capable of sustaining up to 10A maximum carrying current, ensuring safe and efficient energy transfer across pouch cell architectures.

Designed to support both prototype laboratory research and scaled battery manufacturing, this cathode tab material integrates seamlessly into modern pouch cell packaging workflows. Its metallurgical properties facilitate reliable ultrasonic metal welding with aluminum current collector foils while supporting airtight, hermetic sealing against pouch packaging film. The component is extensively utilized in consumer electronics, portable medical equipment, light electric vehicles, and specialized energy storage systems requiring flexible, lightweight polymer cell formats.

Engineered for demanding operational environments, the product demonstrates outstanding mechanical ductility, surface uniformity, and chemical stability against standard non-aqueous battery electrolytes. Each precision-slit strip maintains strict dimensional tolerances across length, width, and thickness to eliminate edge burrs and prevent micro-shorting or pouch puncture. With fully customizable sizing options available alongside standard dimensions, this cathode material provides battery engineers with the consistency and process reliability necessary to achieve reproducible cell performance and extended service life.

Key Features

• Ultra-High Purity 99.99% Aluminum Substrate: The core conductor is refined to 99.99% chemical purity, minimizing metallic trace contaminants and oxidation vulnerabilities to deliver maximum electrical conductivity and prolonged electrochemical stability.
• Robust 10A Continuous Current Handling: Engineered to support a maximum continuous current carrying capacity of 10A, providing low temperature rise and minimal Joule heating during rapid cycling and high-drain discharge profiles.
• Precision 8mm Width Geometry: The calibrated 8mm width profile provides optimal contact surface area for low-resistance ultrasonic welding to cathode foil stacks while remaining compatible with standard pouch cell header configurations.
• Optimized 0.15mm Thickness for Ultrasonic Welding: The 0.15mm foil gauge offers a balanced compromise between mechanical rigidity and ultrasonic bondability, preventing foil tearing or horn perforation during automated tab-to-current collector joining.
• Ultra-Lightweight 80mg Single-Piece Mass: At a net weight of approximately 80mg per unit, this component adds minimal non-active mass to the finished pouch cell, helping engineers optimize gravimetric energy density in lightweight battery packs.
• Fully Customizable Dimensional Options: While supplied at a standardized 48mm overall length, comprehensive custom slitting and shearing services accommodate application-specific length, width, and surface coating requirements.
• Superior Electrolyte and Corrosion Resistance: The high-purity aluminum matrix forms a naturally protective, dense passive oxide layer that resists corrosion from lithium salts (such as LiPF6) and organic carbonate solvent formulations.
• Clean, Burr-Free Edge Processing: Precision mechanical slitting ensures smooth edges free of metallic slivers, flash, or severe curling, safeguarding delicate separator membranes and laminate pouch films during cell assembly.
