Battery-Grade Porous Copper Foil

Product Type: Porous copper foil current collector
Research-grade laboratory product

Product Overview

Battery-grade porous copper foil is a copper current collector material with 4.5-10 μm base foil thickness, 100-1000 mm width and selectable pore diameter of 5-10 μm or 10-20 μm.

The porous structure is described as improving adhesion between negative electrode material and copper foil, improving wetting with slurry and electrolyte, and supporting high-rate charge-discharge behavior.

Performance Features
  • Copper purity is specified at ≥99.8% and listed as ≥99.9% T2.
  • Pore count is specified at ≥5000 pores/cm2.
  • Pore uniformity is specified at ≥90%.
  • Dyne value is specified at ≥40 and oxidation resistance is OK at 140 °C for 15 minutes.
