The electrode sheet requires vacuum baking at 100°C for 12 hours before thermal assembly to ensure proper performance. The material is moisture-sensitive and must be handled in controlled laboratory environments to prevent contamination.
- Vacuum Baking Requirement: The electrode sheet must be vacuum baked at 100°C for 12 hours prior to thermal assembly.
- Moisture Sensitivity: Handle the material in dry, inert conditions to prevent moisture absorption and phase contamination.
- Laboratory Compliance: All processing must adhere to strict laboratory research grade standard compliance conditions.
What is the significance of the 94.50% active material ratio and double-side coating for sodium-ion battery anode performance?
The high active material ratio of 94.50% minimizes binder and conductive additive content, maximizing the reversible capacity of 300 mAh/g. The double-side coating at 15 mg/cm² ensures uniform mass loading and optimal layer uniformity, critical for reproducible electrochemical characterization in sodium-ion R&D.
What is the required vacuum baking procedure before assembling the HC-D04 electrode into a sodium-ion cell?
The HC-D04 electrode requires a standard preparation of 12 hours under vacuum baking at 100°C before thermal assembly. This step is essential to remove moisture and adsorbed gases from the hard carbon and carbon-coated aluminum foil, preventing phase contamination and ensuring consistent electrochemical performance.
How should the carbon-coated aluminum foil substrate of the HC-D04 electrode be handled to maintain mechanical anchoring and low contact resistance?
The carbon-coated aluminum foil substrate is designed to maximize mechanical anchoring and decrease contact resistance, but it must be handled with care in appropriate laboratory environments to prevent moisture absorption or phase contamination. The electrode sheets are packaged securely in sets of 5 to maintain batch validation constants, and should be stored in a dry, inert atmosphere before use.
This double-side-coated hard carbon anode (94.5% active material, 300 mAh/g on a carbon-coated aluminum foil) is configured for sodium-ion battery R&D, delivering uniform 15 mg/cm² loading for reproducible cell builds, but it requires a 12-hour vacuum bake at 100°C before assembly and strict moisture control.
Positive
- High active material ratio with 300 mAh/g capacity: The 94.50% hard carbon active material loading supports a reversible capacity of 300 mAh/g, providing a high-fidelity anode platform for sodium-ion cell evaluation.
- Carbon-coated aluminum current collector: The carbon-modified foil substrate enhances mechanical anchoring of the coating and reduces contact resistance, improving electrode integrity and electrochemical interface performance.
Trade-offs
- Requires 12-hour vacuum bake before use: The electrode sheet must be vacuum-baked at 100°C for 12 hours prior to thermal assembly, adding a mandatory preparation step and requiring vacuum oven infrastructure.
- Sensitive to moisture and phase contamination: The product must be handled in appropriate laboratory environments to prevent moisture absorption or phase contamination, necessitating controlled storage and dry handling conditions.
