Graphite Single-Sided Anode Sheet, 7.2 mg/cm2
Graphite is a layered carbon anode material for lithium-ion batteries. This ready-to-use sheet is supplied for laboratory cell assembly and material evaluation in the listed Single-Sided, 7.2 mg/cm2 configuration.
Material Characteristics
- Layered carbon structure
- Established lithium-ion negative-electrode material
- Coated sheet for half-cell and full-cell research
Typical Research Uses
Use for lithium-ion half-cell testing, full-cell assembly, electrolyte studies, and anode-cathode balancing.
How to Read This Configuration
Use the listed areal loading and side basis when matching graphite with a lithium-ion cathode sheet.
- Areal loading: 7.2 mg/cm2. Use this value as the coating-mass basis when comparing electrode configurations.
- Active material ratio: 96.50% is the listed active-material fraction of the coating formulation. The actual active mass still depends on the punched electrode mass.

This electrode sheet is moisture-sensitive and must be handled in a dry environment to prevent performance degradation. Storage in an inert atmosphere is recommended to maintain electrode integrity before cell assembly.
- Moisture Sensitivity: Store opened sheets in a dry environment or inert atmosphere to reduce moisture exposure.
- Physical Handling: Avoid touching, bending, scratching, or contaminating the coated surface during punching, transfer, and stacking.
- Mass Calculation: Calculate active material mass from the coating loading, active material ratio, and punched electrode area for cell balancing.
- Dry Environment: Use a dry handling environment before cell assembly to reduce moisture exposure on the coated electrode surface.
This procedure describes the recommended handling and preparation steps for the electrode sheet before cell assembly. Following these steps minimizes moisture exposure and physical damage to ensure reproducible experimental results.
Required Equipment:
- Transfer to Dry Environment
Transfer the electrode sheet to a dry environment or inert atmosphere glovebox before opening the packaging. - Punch Electrode
Punch the electrode sheet to the desired dimensions using a clean die, ensuring no contact with the coated surface. - Calculate Active Mass
Calculate the active material mass from the coating loading, active material ratio, and punched electrode area for cell balancing. - Store Remaining Sheets
Store any remaining sheets in a sealed container under inert atmosphere to minimize moisture exposure.
What is the basis for calculating active material mass and N/P ratio when using this graphite anode sheet in full-cell experiments?
The product specification provides the coating loading (7.2 mg/cm²), active material ratio (96.50%), and collector areal density (5.45 mg/cm²) as direct inputs for calculating the active material mass of punched electrodes. These values enable researchers to determine the N/P ratio when pairing with a cathode sheet of known areal capacity, as stated in the product's selection logic section.
What is the structure of the current collector in this anode sheet, and how does the carbon coating affect electrode adhesion and electrolyte compatibility?
The current collector is a carbon-coated copper foil with a symmetrical structure: 1 µm carbon coating / 6 µm copper foil / 1 µm carbon coating. The carbon coating on both sides improves adhesion of the graphite coating to the copper and may enhance electrolyte wetting and interfacial stability, as detailed in the specification table.
What are the recommended storage and handling conditions for this graphite anode sheet to prevent moisture uptake and contamination?
The product should be stored and handled in a dry environment or inert atmosphere to minimize moisture exposure before cell assembly. Avoid touching, bending, scratching, or contaminating the coated surface during punching, transfer, and stacking. The handling section explicitly states these requirements for opened sheets.
This single-sided graphite anode sheet is specified with a 7.2 mg/cm2 coating loading, 96.50% active material ratio, and a carbon-coated copper current collector, providing a defined basis for punched-electrode mass and N/P ratio calculations in lithium-ion cell research. It must be handled in a dry environment and protected from mechanical damage before assembly.
Positive
- Defined coating loading for cell balancing: The 7.2 mg/cm2 coating loading and 96.50% active material ratio give a calculable basis for punched-electrode active mass and N/P ratio in full-cell or half-cell experiments.
- Carbon-coated copper current collector with defined areal density: The symmetric 1 µm carbon / 6 µm copper / 1 µm carbon collector at 5.45 mg/cm2 provides a specified substrate for consistent electrode thickness and mass calculations.
Trade-offs
- Dry-environment handling required: The coated surface must be handled and stored in a dry environment or inert atmosphere before assembly to reduce moisture exposure, requiring controlled laboratory conditions.
- Coated surface vulnerable to mechanical damage: Touching, bending, scratching, or contaminating the coated surface during punching, transfer, and stacking must be avoided, so careful electrode processing is necessary.
