This document outlines handling constraints for the double-side coated hard carbon anode sheet. The electrode requires careful handling to prevent delamination and contamination during cell assembly.
- Coating Delamination Risk: The double-sided coating is susceptible to delamination if subjected to bending or excessive mechanical stress.
This procedure describes the steps to prepare the hard carbon electrode sheet for use in sodium-ion coin cells. Proper handling ensures minimal contamination and optimal electrochemical performance.
Required Equipment: Precision cutter, Argon-filled glovebox
- Inspect
Inspect the electrode sheet for any visible defects, tears, or uneven coating before cutting. - Cut
Cut the electrode sheet to the required dimensions using a clean, sharp precision cutter to avoid edge fraying. - Transfer
Transfer the cut electrode to an argon-filled glovebox for storage and subsequent cell assembly to prevent moisture exposure.
How does the 17 mg/cm² areal loading trade off against achievable capacity in full sodium-ion cells using the HC-D02 hard carbon anode?
At 17 mg/cm² areal loading, the HC-D02 delivers a reversible capacity of 300 mAh/g based on the active material ratio of 93.50%. This loading density balances high mass loading with uniform coating via wet processing, but it may require optimized cell balancing to avoid anode limitation. The compaction density of 0.96 g/cm³ provides structural integrity while maintaining electrolyte wetting properties.
Is the carbon-coated aluminum foil current collector on the HC-D02 compatible with both aqueous and organic solvent-based electrode binder systems?
The HC-D02 substrate is explicitly carbon-coated aluminum foil designed to decrease interfacial polarization and improve mechanical adhesion. While the standard product uses a wet process with unspecified binder, the carbon coating layer is optimized for organic carbonate electrolyte systems typically used in sodium-ion cells. Aqueous binders like CMC/SBR may be compatible but require verification of coating adhesion after vacuum baking at 100°C.
What pre-conditioning protocol is required for the HC-D02 hard carbon anode before cell assembly?
The recommended conditioning standard is 12 hours of vacuum baking at 100°C. This removes adsorbed moisture from the hard carbon and carbon-coated foil, preventing parasitic side reactions in sodium-ion cells. The vacuum baking also stabilizes the compaction density of 0.96 g/cm³ for consistent electrochemical performance.
This double-sided hard carbon anode on carbon-coated aluminum foil delivers a 93.5% active material ratio and a 300 mAh/g reversible capacity, but requires 12-hour vacuum baking at 100°C and careful handling due to the 12 μm substrate thickness.
Positive
- High active material yield: 93.50% active hard carbon ratio with a 300 mAh/g reversible capacity provides reliable electrochemical performance for sodium-ion anode R&D.
- Uniform wet process coating: Standardized 17 mg/cm² double-side wet coating ensures consistent mass loading across the electrode surface for reproducible testing.
Trade-offs
- Vacuum baking preconditioning: The electrode requires 12 hours of vacuum baking at 100°C before use, adding a mandatory processing step and time constraint.
- Thin substrate handling: The 12 μm carbon-coated aluminum foil current collector is mechanically delicate and may require careful handling during cell assembly to avoid damage.
