10μm Ultra Clean Aluminum Foil for Battery Cathode Collector

The 10μm Ultra Clean Aluminum Foil serves as cathode current collector for mainstream 3C lithium batteries, widely used in smartphones, notebooks and wearable electronic devices to realize lightweight cells. It perfectly matches medium-thickness ternary power batteries for light electric vehicles and consumer drones, balancing mechanical strength and high energy density. This high-cleanliness foil is also suitable for small energy storage capacitors and laboratory sodium-ion battery research, effectively suppressing side reactions triggered by surface contaminants.

Key Bnenefit of 10μm Ultra Clean Aluminum Foil

a. Superior Low Interfacial Resistance. Our non-permeable coating technology delivers minimized contact resistance and unimpeded electron conduction.

b.Ultra High Purity. Precision acid cleaning eliminates surface grease and micro-impurities, greatly enhancing the binding force of cathode active materials.

c. Ultra-Thin & Lightweight Design. Cathode aluminum foil has evolved from the traditional 12–16 μm down to an ultra-thin 8 μm specification. This thin gauge cuts down overall cell weight and elevates battery energy density, making it an ideal choice for long-range new energy vehicles and 3C electronics including smartphones and laptops.
