battery-grade aluminum foil

The 10μm Ultra Clean Aluminum Foil is a battery-grade aluminum foil , which goes through an acid cleaning procedure in production to strip residual grease and surface contaminants, and features zero barrier coating treatment. It has much tighter tolerance control over thickness, mechanical strength and surface cleanliness compared with ordinary aluminum foil. The manufacturing goal is to achieve minimized thickness, maximized tensile strength, optimized Dyna index and ultra-clean surface finish.
