How does the compaction density of 1.31 g/cm³ affect the rate capability of this dry-process graphite anode?
The compaction density of 1.31 g/cm³ represents a moderate densification level for a dry-process electrode, balancing active material loading with ionic transport pathways. At this density, the electrode maintains adequate porosity for electrolyte wetting and lithium-ion diffusion, supporting the rated capacity of 350 mAh/g. Higher compaction densities would increase volumetric energy but risk rate capability degradation due to reduced pore connectivity.
Can this single-sided graphite anode be paired with standard lithium-ion battery counter electrodes in a research cell?
Yes, the S04-Graphite electrode is designed for lithium-ion battery R&D and its carbon-coated copper foil substrate is compatible with conventional cell assembly methods. The dry-process coating structure and 96% active material ratio ensure reliable electrochemical performance when paired with suitable counter electrodes. Note the coating area of 90×120 mm and substrate size of 90×140 mm, which require careful cell hardware alignment to avoid shorting at exposed copper foil edges.
What are the recommended vacuum baking conditions before cell assembly for this dry-process graphite electrode?
The electrode sheet requires vacuum baking at 100°C for 12 hours to remove residual moisture and ensure optimal electrochemical performance as specified in the product documentation. This condition is critical for dry-process electrodes to achieve consistent anode lithiation behavior. Post-baking, electrodes should be stored under inert atmosphere in a dry room to prevent moisture reabsorption.
This graphite anode sheet features a 96% active material ratio and single-sided dry process coating at 27.4 mg/cm² areal density, requiring vacuum baking at 100°C for 12 hours before use. Designed for Li-ion battery R&D, the carbon-coated copper substrate provides a compact density of 1.31 g/cm³ with a rated capacity of 350 mAh/g.
Positive
- High active material ratio: 96% active graphite content maximizes electrochemical utilization, delivering reliable capacity of 350 mAh/g for consistent performance analysis.
- Dry process coating: Solvent-free fabrication eliminates residual binder solvents, ensuring uniform coating density and compatibility with high-precision R&D testing.
Trade-offs
- Extended vacuum bake required: Sheets must be vacuum-baked at 100°C for 12 hours prior to use, demanding oven infrastructure and scheduling lead time.
- Single-sided coating limitation: Single-side coating restricts cell design to configurations that accommodate one active layer, and the 90×120 mm coating area limits electrode geometry flexibility.
