LiCoO2 (LCO) Single-Side Coated Aluminum Foil Description

LiCoO2 (LCO) Single-Side Coated Aluminum Foil is a key cathode material used in lithium-ion battery research and development. It consists of a uniform coating of lithium cobalt oxide (LiCoO2) applied to one side of high-purity aluminum foil. LiCoO2 is a widely adopted cathode material thanks to its high energy density, stable voltage profile, and long cycle life. The aluminum foil serves as a lightweight, conductive current collector that provides mechanical support and excellent electrical contact.

This coated foil is manufactured by dispersing LiCoO2 powder, a conductive carbon additive such as Super P, and a binder like PVDF (polyvinylidene fluoride) in a solvent such as N-methyl-2-pyrrolidone (NMP) to form a uniform slurry. The slurry is then coated onto one side of the aluminum foil using techniques like doctor blade or roll-to-roll coating. After drying and calendaring, the foil exhibits a smooth, dense electrode layer with strong adhesion and consistent electrochemical properties.

LiCoO2 single-side coated foil is ideal for coin cell assembly, lab-scale battery prototyping, and academic studies focused on electrochemical performance, capacity retention, and degradation mechanisms. It is commonly used in consumer electronics, wearable devices, and other applications where energy density and reliability are critical.

1.       Common Preparation Methods

The preparation of LiCoO2 (LCO) Single-Side Coated Aluminum Foil involves creating a homogeneous slurry by mixing lithium cobalt oxide (LiCoO2) powder with a conductive carbon additive such as Super P and a binder like polyvinylidene fluoride (PVDF) in a solvent such as N-methyl-2-pyrrolidone (NMP). The slurry is thoroughly mixed to ensure uniform dispersion of the active materials and then applied to one side of high-purity aluminum foil using a coating technique such as doctor blade or slot-die coating. After coating, the foil is dried in a vacuum or convection oven to remove the solvent and promote binder adhesion. It is then calendared using precision rollers to densify the electrode layer, improve particle contact, and ensure a consistent thickness across the surface. The final product is inspected for coating uniformity, adhesion, and mechanical stability before being cut into required shapes or stored for further use in battery assembly and testing. This process results in a high-quality, ready-to-use cathode material suitable for lithium-ion coin cell fabrication, laboratory research, and electrochemical performance evaluation.
