The electrode sheet is moisture-sensitive and requires controlled vacuum drying before thermal validation testing. The mandatory protocol is 12 hours under vacuum at 100°C to prevent moisture contamination or structural degradation.
- Vacuum baking requirement: Process and maintain the electrode sheets for 12 hours under vacuum at 100°C before thermal validation testing workflows.
- Moisture contamination prevention: Maintain strictly vacuum conditions throughout the baking protocol to completely prevent moisture contamination.
- Structural degradation prevention: Complete the full vacuum drying cycle before thermal validation testing to avoid structural degradation of the electrode sheet.
This protocol describes the required vacuum drying treatment for Atomfair HC-S04 hard carbon electrode sheets before thermal validation testing. The sheets must be processed and maintained under vacuum at 100°C for 12 hours.
Required Equipment: Vacuum oven capable of maintaining 100°C
- Set vacuum oven conditions
Set the vacuum oven to maintain 100°C under vacuum for the drying cycle. - Load electrode sheets
Load the electrode sheets into the vacuum oven for the baking protocol. - Maintain drying cycle
Maintain the electrode sheets under vacuum at 100°C for 12 hours to prevent moisture contamination or structural degradation.
How does the active material ratio of 94.5% in the HC-S04 hard carbon electrode sheet affect its electrochemical performance for sodium-ion battery applications?
The high active material ratio of 94.5% ensures a capacity of 300 mAh/g and minimizes binder/additive interference, providing reliable electrochemical performance. The uniform coating density of 6.6 mg/cm² further supports consistent cell-to-cell results in sodium-ion battery research.
What substrate and current collector configuration does the HC-S04 electrode sheet use, and what are the implications for cell assembly?
The HC-S04 electrode uses a carbon-coated aluminum foil substrate with a current collector density of 3.3 mg/cm² and a substrate thickness of 12+0.5+0.5 μm. This configuration ensures low contact resistance and excellent adhesion, but the single-sided coating requires careful handling to avoid damage during cell assembly.
What is the recommended drying protocol for the HC-S04 hard carbon electrode sheet to ensure optimal performance?
The recommended protocol is to bake the electrode sheets under vacuum at 100°C for 12 hours to eliminate moisture and prevent structural degradation. This step is critical before any thermal validation testing workflows to maintain material integrity.
The Atomfair HC-S04 hard carbon electrode sheet offers a 94.5% active material loading on a carbon-coated aluminum foil substrate, providing consistent 6.6 mg/cm² coating for sodium-ion battery research. However, it requires a 12-hour vacuum baking at 100°C to prevent moisture contamination and is single-sided coated, which may limit cell assembly options.
Positive
- High active material purity: The 94.50% hard carbon active material ratio ensures targeted electronic pathways and reliable half-cell testing control.
- Stable carbon-coated aluminum substrate: Carbon-coated aluminum foil provides excellent active layer adhesion, secure electrical contact, and reduced contact resistance.
Trade-offs
- Mandatory vacuum baking protocol: The electrode sheets must be baked under vacuum at 100°C for 12 hours to prevent moisture contamination or structural degradation before use.
- Single-sided coating limitation: The single-sided coating on a 110 × 80 mm active area may restrict configurations requiring double-sided electrodes for full-cell assembly.
