Hard carbon is a non-graphitic carbon anode material for sodium-ion batteries. This ready-to-use sheet is supplied for laboratory cell assembly and material evaluation in the listed Single-Sided, 8.5 mg/cm2, 152 x 110 mm, 5-Pack configuration.
Material Characteristics
- Disordered, non-graphitic carbon structure
- Sodium-ion negative-electrode material
- Coated sheet for half-cell and full-cell research
Typical Research Uses
Use for sodium-ion half-cell studies, cathode-anode pairing, electrolyte evaluation, and full-cell assembly.
How to Read This Configuration
Match the hard-carbon loading and side basis with the sodium-ion cathode and balancing method used in the experiment.
- Areal loading: 8.5 mg/cm2. Use this value as the coating-mass basis when comparing electrode configurations.
- Active material ratio: 93.50% is the listed active-material fraction of the coating formulation. The actual active mass still depends on the punched electrode mass.
- Compaction density: 0.96 g/cm3 is a physical electrode parameter. Interpret it with loading, thickness, porosity, and the source measurement method.
- Capacity basis: 300 mAh/g is retained as an active-material reference value, not a guaranteed cell-level result.

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
- Transfer sheets to vacuum oven
Transfer the electrode sheets from their atmosphere-controlled packaging directly into a vacuum oven preheated to 100°C. - Evacuate and maintain vacuum
Evacuate the oven chamber to a stable vacuum level and maintain the temperature at 100°C for 12 hours. - Cool under vacuum before use
Allow the sheets to cool to room temperature under vacuum before removing them for subsequent thermal validation testing.
Why is ATOMFAIR® HC-S05 preferred as an advanced sodium-ion battery anode material?
ATOMFAIR® HC-S05 functions as a premier advanced sodium-ion battery anode material for advanced systems. It delivers a reliable specific capacity of 300 mAh/g through an optimized hard carbon matrix, significantly boosting performance metrics and phase purity during laboratory testing workflows.
How to prevent ambient moisture contamination?
To successfully solve how to prevent ambient moisture contamination without secondary contamination, this material must be handled strictly according to vacuum baking at 100°C for 12 hours before thermal processing.
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.
