Single-sided Carbon-coated Copper Foil University Experimental Lithium Battery Current Collector Double-sided Carbon-coated Copper Foil Lithium-sulfur Battery Grade Copper Foil

1. Product Overview

Our Carbon-Coated Copper Foil is a high-performance conductive substrate designed for lithium-ion battery anodes, particularly for high-energy-density applications. With a uniform carbon coating and ultra-high-purity copper base, this foil enhances electrode conductivity, adhesion, and cycle stability, making it ideal for EV batteries, energy storage, and consumer electronics.

2. Key Features

Superior Conductivity:

Surface resistivity <30Ω/25μm² (low impedance for efficient charge transfer).
Copper purity >99.99%!(MISSING) ensures minimal energy loss.
Mechanical Strength:
Tensile strength ≥265MPa and elongation rate ≤6.0%!(MISSING) (resists cracking during electrode processing).
Precision Coating:
Single-side carbon layer (1μm) + total thickness 12±1μm (uniform and controllable).
Customizable Dimensions:
Standard width: 260±1mm (coating width: 227±1mm).
