LiCoO2 (LCO) Double-Side Coated Aluminum Foil Description
LiCoO2 (LCO) Double-Side Coated
Aluminum Foil is a premium cathode material engineered for advanced lithium-ion
battery applications. It consists of lithium cobalt oxide (LiCoO2) uniformly
coated on both sides of high-purity aluminum foil, significantly increasing the
active material loading and overall energy density compared to single-side
coated electrodes. This configuration is especially beneficial in compact or
high-performance battery designs where space and weight are critical.
The foil is prepared by creating a
homogeneous slurry of LiCoO2 powder, conductive carbon additives (such as Super
P), and a binder like polyvinylidene fluoride (PVDF) in a solvent such as
N-methyl-2-pyrrolidone (NMP). The slurry is applied to both sides of the
aluminum foil using precise coating techniques like roll-to-roll or slot-die
coating. After coating, the material is dried, calendared to increase electrode
density and mechanical strength, and then cut to size for use in coin cells,
pouch cells, or cylindrical cell prototypes.
LCO double-side coated foil
provides excellent cycle life, voltage stability, and energy capacity, making
it ideal for research laboratories, product development, and performance
benchmarking. It is widely used in consumer electronics, wearable devices, and
other compact energy storage systems requiring reliable, high-energy cathode
materials.

1. Common Preparation Methods
The preparation of LiCoO2 (LCO)
Double-Side Coated Aluminum Foil begins by formulating a uniform slurry
composed of lithium cobalt oxide (LiCoO2) powder, a conductive additive such as
Super P carbon black, and a binder like polyvinylidene fluoride (PVDF)
dissolved in N-methyl-2-pyrrolidone (NMP) solvent. This slurry is mixed
thoroughly to ensure even dispersion of all components. The mixed slurry is
then applied to both sides of a high-purity aluminum foil using a roll-to-roll
or slot-die coating process. Once coated, the foil is dried in a vacuum or
convection oven to remove solvent residues and promote strong binder adhesion.
The dried material is subsequently passed through calendaring rollers to
densify the electrode layers, enhance mechanical strength, and improve the
contact between particles. After calendaring, the double-side coated foil is
inspected for uniformity, thickness consistency, and adhesion quality. The
final product is then slit or punched into desired dimensions, ready for use in
lithium-ion battery fabrication and electrochemical testing. This method
ensures a balanced, high-performance cathode material suitable for applications
demanding higher energy density and compact design.
