Ultra thin cathode aluminum foil

The 9μm Ultra Clean Aluminum Foil is designed for lithium battery applications, ultra-clean aluminum foil undergoes acid washing during manufacturing to eliminate surface oil stains and micro-impurities, without any barrier coating on its surface. Unlike standard aluminum foil, it adopts far stricter production standards for thickness, tensile strength and surface cleanliness. Its production targets ultra-thin gauge, superior mechanical strength, ideal Dyna value and spotless surface condition.
