Youveim® offers a range of high-performance aluminum foil products widely used in lithium-ion batteries, supercapacitors, and other electrochemical devices as cathode current collectors.
Based on surface finish and carbon coating treatment, the aluminum foils are categorized into the following four types:
Features: One side shiny, one side matte; good flexibility and basic conductivity.
Applications: Ideal for winding or stacking-type battery structures; suitable for early-stage process development and cost-sensitive experiments.
Features: Both sides shiny with excellent surface flatness and high conductivity.
Applications: For cathode systems requiring high surface consistency; helps enhance energy density and cycle performance.
Features:
One side coated with conductive carbon, improving adhesion of active materials;
Reduces interface resistance and enhances electron pathways;
Back side remains bare aluminum.
Applications: Suitable for high-power batteries, solid-state batteries, and cathodes using high-resistance materials (e.g., high-nickel, LFP).
Features:
Conductive carbon coating on both sides;
High uniformity and consistent charge distribution.
Applications: Designed for double-sided electrodes; enhances conductivity and cycling stability. Suitable for high-rate discharge batteries, pouch cells, and multi-layer stacked electrodes.
