Copper Foam Electrode Material for Lithium Battery and Supercapacitor Substrates

Product Overview

This open-cell copper foam is an advanced metallic structural material engineered specifically to meet the demanding requirements of next-generation electrochemical energy storage, thermal dissipation, and industrial filtration systems. Built with an interconnected three-dimensional metallic skeleton, the material delivers a continuous conducting network combined with an exceptionally high surface area. It significantly reduces interfacial resistance while facilitating rapid ion and electron transport, making it an ideal conductive scaffold for high-power battery chemistry and energy storage research.

Designed primarily for research laboratories and industrial manufacturing lines, this porous substrate is widely utilized in lithium-ion and lithium-metal battery anodes, electric double-layer capacitors (EDLC), pseudocapacitors, and nickel-zinc alkaline battery systems. Beyond energy storage, the structural versatility of the material enables superior performance in organic chemical catalytic substrates, high-heat electronics cooling, electromagnetic interference (EMI) shielding enclosures, and fluid pressure damping systems across the aerospace, automotive, and chemical processing sectors.

Manufactured under rigorous process controls, this metallic foam guarantees structural consistency, high open-cell connectivity, and superior mechanical resilience under mechanical compression and thermal cycling. The substrate maintains structural stability without collapsing or shedding metallic particles during roll-to-roll calendering, slurry loading, or prolonged high-rate charging and discharging, ensuring long-term repeatability and process reliability in demanding research and commercial applications.

Key Features

• Interconnected 3D Porous Skeleton: Features an open-cell porous matrix with a through-hole ratio of ≥98% and overall porosity of ≥98%, ensuring unobstructed electrolyte permeability, minimal tortuosity, and rapid mass transport throughout the entire electrode volume.
• Superior Electrical Conductivity: The solid metallic copper backbone provides continuous electronic conduction paths, dramatically reducing internal resistance (ESR) and polarization in high-rate lithium batteries and supercapacitors.
• Exceptional Thermal Dissipation: Leveraging the high thermal conductivity of pure copper, the material rapidly draws heat away from concentrated thermal zones in high-power battery packs, electric motors, and high-frequency electronic components.
• Expansive Specific Surface Area: The highly porous micro-cellular geometry allows for uniform, high-mass loading of active electrode slurries, solid-state electrolytes, or catalytic coatings without compromising volumetric efficiency.
• Advanced Acoustic Attenuation & EMI Shielding: High surface tortuosity enables diffuse reflection and viscous micropore dissipation for sound dampening, while the continuous copper matrix provides electromagnetic shielding performance comparable to solid silver foils.
• Mechanical Flexibility & Workability: Offers excellent plasticity and compressibility, allowing researchers to cut, stamp, fold, or calender the sheets to exact dimensional tolerances without disrupting the continuous conductive network.
• High Chemical & Fluid Buffering Efficiency: Provides uniform fluid pressure dispersion to protect delicate downstream pressure instrumentation, combined with non-toxic, biocompatible handling characteristics suited for medical and water filtration.
