Lithium-coated copper foil represents a pinnacle architecture for the negative electrode in next-generation Anode-Free Lithium Metal Batteries (AFLMBs) and thin-film All-Solid-State Batteries (ASSBs). By pre-depositing an ultra-thin layer of metallic lithium (< 20 um) onto a high-conductivity copper current collector, this composite architecture bridges the gap between traditional graphite anodes and the idealized, pure "anode-free" configuration. It provides a strategic lithium reservoir to compensate for irreversible capacity loss during early cycling while maintaining high volumetric and gravimetric energy densities.

To effectively replace standard bulk lithium foil (which is typically 50 to 150 um thick and introduces heavy volumetric dead weight), engineered lithium-coated copper foils must meet precise geometric and chemical targets: (1) Copper Substrate Thickness: Typically 4.5\ um to 9 um. Ultra-thin, battery-grade rolled-annealed (RA) or electrodeposited (ED) copper foil is preferred to maximize energy density. (2) Lithium Coating Thickness: Typically customized from 1um to 20um depending on the specific capacity matching requirements of the cathode. (3) Capacity Contribution: A 1um thick layer of pure lithium corresponds to an areal capacity density of approximately 0.206 mAh cm^{-2}. Therefore, a 10 um coating delivers ~2.06 mAh cm^{-2}, aligning perfectly with commercial lean-lithium protocols.

Sample Package

The lithium coated copper foil roll is sealed in an aluminum can that is further sealed in a vacuum bag.    

Attention

The aluminum can with lithium coated copper foil roll must be opened inside a glove box with Argon Gas and moisture less than 1%RH (0.1 ppm is better).
