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.
