Hard Carbon HC-S05 Electrode Sheet 300 mAh/g ATOMFAIR®

This material is moisture-sensitive and must be stored under strict atmosphere to prevent ambient contamination before use. Structural degradation may occur if the recommended vacuum baking protocol is not followed prior to thermal processing.

• Moisture Sensitivity: Ambient moisture exposure can cause structural degradation and compromise electrochemical performance.
• Vacuum Baking Requirement: A 12-hour vacuum bake at 100°C is required to remove residual moisture before thermal validation testing.
• Atmosphere-Controlled Packaging: Sheets are packaged under strict atmosphere to maintain batch uniformity and prevent contamination during storage.

This protocol describes the required vacuum baking step to remove ambient moisture from the electrode sheets before thermal processing. Proper preparation ensures data integrity and prevents structural degradation during electrochemical evaluation.

Required Equipment: Vacuum oven capable of maintaining 100°C

1. Transfer sheets to vacuum oven
   Transfer the electrode sheets from their atmosphere-controlled packaging directly into a vacuum oven preheated to 100°C.
2. Evacuate and maintain vacuum
   Evacuate the oven chamber to a stable vacuum level and maintain the temperature at 100°C for 12 hours.
3. Cool under vacuum before use
   Allow the sheets to cool to room temperature under vacuum before removing them for subsequent thermal validation testing.

The Atomfair HC-S05 hard carbon electrode sheet is a research-grade anode material for sodium-ion batteries, featuring a 93.50% active material ratio, precision wet-process coating at 8.5 mg/cm² loading density, and a carbon-coated aluminum foil substrate that reduces contact resistance. Its single-sided design and strict moisture sensitivity requiring vacuum baking at 100°C for 12 hours are key operational constraints for lab deployment.

Positive

• High-purity hard carbon matrix: The 93.50% active material ratio preserves targeted electronic pathways and ensures consistent half-cell testing results.
• Uniform coating and stable substrate: Precision wet-process coating delivers a uniform 8.5 mg/cm² loading density, while the carbon-coated aluminum foil provides excellent adhesion and low contact resistance for reliable electrical contact.

Trade-offs

• Mandatory vacuum baking protocol: The electrode sheets must be vacuum-baked at 100°C for 12 hours to prevent ambient moisture contamination, adding a required pre-processing step before thermal validation.
• Single-sided coating design: The product is single-side coated, which limits its use to specific cell configurations and may require additional handling for double-sided applications.
