The electrode sheet requires vacuum baking at 100°C for 12 hours prior to cell integration to remove adsorbed moisture and ensure electrochemical stability. The material must be handled in a controlled laboratory environment to prevent ambient contamination that could degrade performance.
- Pre-Integration Vacuum Baking: Condition the electrode sheet under vacuum at 100°C for 12 hours before assembling into a cell.
- Contamination Control: Handle the electrode sheet in an appropriate laboratory environment to avoid exposure to ambient contaminants.
What is the reversible capacity of the Atomfair HC-D02 hard carbon electrode sheet, and how does the compaction density affect its performance in sodium-ion batteries?
The HC-D02 electrode sheet delivers a reversible capacity of 300 mAh/g with an active material ratio of 93.50%. The compaction density of 0.96 g/cm³, combined with the 17 mg/cm² double-sided coating density, ensures uniform structural properties and consistent electrochemical behavior in sodium-ion battery R&D.
What preconditioning is required before using the Atomfair HC-D02 hard carbon electrode sheet in cell assembly?
The electrode sheets require vacuum baking at 100°C for 12 hours prior to initial cell integration. This conditioning step is essential to remove moisture and volatile contaminants, ensuring reliable benchmarking and eliminating variability in electrochemical diagnostics.
What is the current collector construction of the HC-D02 electrode sheet, and how does it support anode performance?
The HC-D02 uses a carbon-coated aluminum foil current collector with an areal density of 3.53 mg/cm² and a total substrate thickness of 13 μm (12 μm foil + 0.5 μm carbon coating on each side). The carbon coating decreases interfacial polarization limits and improves mechanical adhesion, critical for long-cycle sodium-ion anode testing.
The Atomfair HC-D02 hard carbon electrode sheet, double-side coated at 17 mg/cm² via wet process on carbon-coated aluminum foil, offers a 93.5% active material ratio and 300 mAh/g capacity for sodium-ion battery anode R&D, but requires mandatory 12-hour vacuum baking at 100°C before use and is limited to laboratory research environments.
Positive
- High active material ratio: 93.50% active hard carbon content delivers a reliable 300 mAh/g reversible capacity, enabling consistent benchmarking in sodium-ion anode studies.
- Carbon-coated foil current collector: Carbon-coated aluminum substrate reduces interfacial polarization and improves mechanical adhesion between the coating and current collector.
Trade-offs
- Mandatory pre-conditioning step: Requires 12 hours of vacuum baking at 100°C before cell integration, adding processing time and infrastructure demands.
- Laboratory use only restriction: Sold exclusively for laboratory research; not qualified for pilot or production-scale deployment without further validation.
