This hard carbon electrode sheet requires strict moisture control to prevent performance degradation. The double-sided coating necessitates careful handling to avoid delamination and ensure uniform compression.
- Storage Atmosphere Requirement: Store under inert atmosphere or vacuum to minimize moisture adsorption on the hard carbon.
- Substrate Handling Guideline: Handle the carbon-coated aluminum foil with clean, non-abrasive instruments to prevent scratching or contamination.
- Compaction Density Constraint: Calendering must achieve a compaction density of 1 g/cm³ to maintain electrode porosity and mechanical integrity.
- Electrolyte Compatibility Consideration: Select electrolyte formulations that are compatible with hard carbon to avoid irreversible capacity fade and gas evolution.
How does the 15 mg/cm² coating density of the HC-D04 affect its electrochemical performance?
The 15 mg/cm² coating density is achieved via precision wet processing to ensure uniform mass loading and structural integrity, supporting a reversible capacity of 300 mAh/g for sodium-ion battery anodes.
What type of current collector is used in the HC-D04 hard carbon anode?
The HC-D04 uses a carbon-coated aluminum foil current collector with an areal density of 3.53 mg/cm² and substrate thickness of 12 +0.5+0.5 μm, specifically designed to reduce contact resistance and improve mechanical anchoring.
What is the required vacuum baking procedure for the HC-D04 before electrode assembly?
The HC-D04 must be vacuum baked at 100°C for 12 hours prior to use. This standard preparation step is mandatory to ensure the electrode's performance in laboratory research.
The Atomfair HC-D04 hard carbon anode electrode provides a high active material loading of 15 mg/cm² on both sides of a carbon-coated aluminum current collector, delivering a reversible capacity of 300 mAh/g for sodium-ion battery R&D. Researchers must account for the mandatory 12-hour vacuum baking at 100°C prior to use and the double-side coating configuration, which influences cell assembly design.
Positive
- High active material ratio and capacity: With 94.50% active material content and a reversible capacity of 300 mAh/g, the electrode provides high specific energy density suitable for sodium-ion anode characterization.
- Uniform double-side coating on modified foil: Precision wet processing ensures uniform 15 mg/cm² mass loading on both sides, while the carbon-coated aluminum substrate improves mechanical anchoring and reduces contact resistance for reproducible testing.
Trade-offs
- Mandatory vacuum baking pretreatment: The electrode requires 12 hours of vacuum baking at 100°C before use, demanding compatible oven infrastructure and extending preparation lead times.
- Double-side coating limits cell compatibility: The double-side coated design is optimized for symmetric cell configurations and is not directly compatible with conventional half-cell setups that require single-side coated electrodes.
