LiCoO2 Single Side Coated Cathode Electrode Disc Description
LiCoO2 Single Side Coated Cathode
Electrode Disc is a precision-fabricated lithium-ion battery component,
featuring a single-sided coating of lithium cobalt oxide (LiCoO2) on an
aluminum foil substrate. LiCoO2 is a widely used cathode material due to its
high energy density, stable voltage profile, and excellent cycling performance.
The single-sided design allows for controlled material loading, ideal for
prototyping, lab-scale testing, and specialized cell architectures where layer
uniformity is critical.
The Disc is produced by preparing a
slurry of LiCoO2 powder, conductive carbon (such as Super P), and a binder like
polyvinylidene fluoride (PVDF) in a solvent such as N-methyl-2-pyrrolidone (NMP).
This slurry is coated onto one side of the aluminum foil using methods like
doctor blade or slot-die coating, followed by drying and calendaring to achieve
optimal thickness and density. The coated foil is then punched into Disc
shapes, typically used in coin cell assembly or academic electrochemical
studies.
This electrode Disc provides
consistent performance in terms of capacity, voltage, and cycle life, making it
suitable for evaluating cathode behavior in controlled environments. Its
reliability and ease of integration make it a standard material in lithium-ion
battery R&D, including applications in consumer electronics and battery
material screening.

1. Common Preparation Methods
The preparation of the LiCoO₂
Single Side Coated Cathode Electrode Disc begins with creating a homogeneous
slurry by mixing lithium cobalt oxide (LiCoO₂) powder, a conductive additive
such as Super P carbon black, and a binder like polyvinylidene fluoride (PVDF)
in a solvent such as N-methyl-2-pyrrolidone (NMP). This slurry is thoroughly
stirred to ensure uniform dispersion of all components. The mixture is then
coated onto one side of an aluminum foil substrate using techniques like doctor
blade or slot-die coating to achieve a consistent thickness. After coating, the
foil is dried in a vacuum or convection oven to remove the solvent and
partially cure the binder. The dried coated foil is then calendared through
rollers to improve particle contact, reduce porosity, and enhance electrode
density and mechanical strength. Finally, the electrode sheet is punched into
circular Discs of desired dimensions, which are then weighed, inspected for
uniformity, and optionally dried again before being used in coin cell assembly
or electrochemical testing. This process results in a reliable and
high-performance cathode material suitable for research, prototyping, and
performance benchmarking in lithium-ion battery development.
