Ultra-High Dyne Aluminum Foil Current Collector

Ultra-High-Dyne Aluminum Foil

This ultra-high-dyne aluminum foil is designed for use as a cathode current collector in lithium-ion batteries. The material maintains a stable dyne level above 66, supporting slurry wettability, adhesion, surface cleanliness, and coating compatibility. Its mechanical strength and surface quality support use in cathode electrode fabrication.
