📦 Youveim® Battery-Grade Copper Foil Product Introduction

Product Overview:
Youveim® electro-deposited copper foil is made from high-purity copper using an electrochemical process. The foil surface undergoes roughening and anti-oxidation treatments to significantly enhance adhesion between the electrode and active materials. SCI Materials Hub offers a range of battery-grade copper foils, including single-side frosted, double-side shiny, and single/double carbon-coated foils, widely used as anode current collectors for laboratory research and industrial lithium-ion battery production.

Key Features:

  • Excellent electrical conductivity and chemical stability

  • Extremely low surface profile; metal density close to theoretical copper density

  • High elongation and tensile strength

  • Enhances adhesion of anode active materials, improving cycling life

  • Carbon-coated foils reduce interfacial resistance and improve rate performance

Applications:

  • Lithium-ion power storage batteries (Si/C, SiC)

  • Consumer electronics (3C) lithium-ion batteries

  • Aqueous lithium-ion batteries

⚡ Anode Current Collector Usage Instructions

  1. Cut copper foil to the required battery design size.

  2. Clean the foil surface to remove dust, grease, and scratches.

  3. Fix the foil on the anode coating equipment.

  4. Evenly coat the anode slurry (graphite/silicon-carbon active materials).

  5. Dry, then roll-press, cut, and assemble.

  6. Carbon-coated foils can undergo light surface activation before coating to enhance adhesion.


🏭 Coating Process Flow

Copper foil → Surface cleaning → Functional coating application (conductive carbon/resin mixture) → Drying and curing → Winding or cutting → Inspection and packaging
