Lithium Battery Copper Foil, Double-Shiny, Single-Shiny or Double-Rough

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

Product Overview

Lithium battery copper foil is available in double-shiny, single-shiny and double-rough formats with listed thickness options from 4.5 to 12 μm.

The foil supports slurry coating on one or both sides as required and is described with ultra-thin performance, low rough-side peak profile and good coating behavior during adhesion.

Performance Features
  • Available formats include double-shiny, single-shiny and double-rough copper foil.
  • Measured copper purity is at least 99.95% against a specification of at least 99.8%.
  • Measured tensile strength is 35 kg/m2 and room-temperature elongation is 4.5%.
  • Oxidation resistance is marked OK at 140 °C for 15 minutes.
