Si-C Silicon-Carbon Single-Sided Anode Sheet, 4.5 mg/cm2
Silicon-carbon, Si-C, is a composite 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, 4.5 mg/cm2 configuration.
Material Characteristics
- Silicon and carbon composite material system
- Lithium-ion negative-electrode research material
- Coated sheet supplied in a defined side and loading configuration
Typical Research Uses
Use for silicon-containing anode evaluation, electrolyte studies, formation work, and lithium-ion cathode pairing.
How to Read This Configuration
Do not substitute a constituent silicon capacity for the supplied composite electrode; use the listed product basis and actual punched mass in cell calculations.
- Areal loading: 4.5 mg/cm2. Use this value as the coating-mass basis when comparing electrode configurations.
- Active material ratio: 90.30% is the listed active-material fraction of the coating formulation. The actual active mass still depends on the punched electrode mass.
- Current collector: Carbon-Coated Copper Foil, listed as 1 um C / 6 um Cu / 1 um C. This identifies the foil supporting the coating.
- Capacity basis: 1600 mAh/g is retained as an active-material reference value, not a guaranteed cell-level result.

This electrode sheet requires controlled drying and handling to maintain structural integrity and electrochemical performance. Deviations from specified conditions may introduce contamination, delamination, or inaccurate cell calculations.
- Drying Requirement: Dry the electrode sheet at 90-100°C for 12-24 hours prior to cell assembly to remove residual solvent and moisture.
- Handling Environment: Maintain a clean, dry handling environment after drying to prevent moisture adsorption and contamination.
- Mechanical Integrity: Avoid bending, scratching, or contaminating the coated surface during cutting, punching, transfer, and stacking to prevent delamination or performance loss.
- Mass Calculation: Use the actual punched electrode mass, not the areal loading alone, to determine active material content for cell calculations.
- Capacity Reference: The 1600 mAh/g specific capacity is an active-material reference value and does not guarantee cell-level performance.
This procedure outlines the required drying and handling steps for the silicon-carbon anode sheet before cell assembly. Proper execution ensures electrode integrity and reliable electrochemical data.
Required Equipment: Drying oven capable of maintaining 90-100°C
- Dry the electrode sheet
Dry the electrode sheet at 90-100°C for 12-24 hours in a drying oven to remove residual solvent and moisture. - Transfer to clean environment
Transfer the dried sheet to a clean, dry handling environment such as a glovebox or dry room to prevent recontamination. - Punch or cut electrodes
Punch or cut electrodes from the sheet while supporting the coated surface to avoid bending, scratching, or contamination. - Weigh each electrode
Weigh each punched electrode to record the actual mass for accurate active material and capacity calculations.
How should the 1600 mAh/g specific capacity be used in cell-level calculations for this Si-C anode sheet?
The 1600 mAh/g value is an active-material reference capacity, not a guaranteed cell-level result. Actual cell capacity depends on the punched electrode mass and the active material ratio of 90.30%. Do not substitute a constituent silicon capacity for the supplied composite electrode; use the actual punched mass in cell calculations.
What is the current collector structure of this Si-C anode sheet and how does it affect cell assembly?
The current collector is carbon-coated copper foil with a structure of 1 µm C / 6 µm Cu / 1 µm C. This carbon coating provides adhesion and conductivity for the silicon-carbon composite layer. During handling, avoid bending, scratching, or contaminating the coated surface to maintain integrity during cutting, punching, and stacking.
What are the recommended drying conditions for this Si-C anode sheet before cell assembly?
Dry the electrode sheet at 90–100°C for 12–24 hours prior to cell assembly. After drying, use a clean, dry handling environment and avoid any bending, scratching, or contamination of the coated surface to ensure optimal electrode performance.
This Si-C (silicon-carbon) composite anode sheet is configured as a single-sided coating on carbon-coated copper foil at 4.5 mg/cm2 areal loading with 90.30% active material ratio and a specific capacity reference of 1600 mAh/g. It is a ready-to-use research electrode for lab-scale lithium-ion cell assembly, requiring a 12-24 hour drying step at 90-100°C and careful handling to preserve coating integrity.
Positive
- Ready-to-use Si-C anode sheet: Supplied in a defined single-sided, 4.5 mg/cm2 areal loading configuration for immediate laboratory cell assembly, eliminating coating preparation steps.
- Defined material composition: Active material system (Si-C), active material ratio (90.30%), and current collector structure (carbon-coated copper foil) are specified, enabling reproducible cell studies.
Trade-offs
- Extended drying requirement: Electrode sheet must be dried at 90-100°C for 12-24 hours before cell assembly, requiring oven access and careful scheduling.
- Handling sensitivity: Coated surface must not be bent, scratched, or contaminated during cutting, punching, transfer, and stacking; clean dry handling environment is mandatory after drying.
