NCM811 Single Sided Cathode 24 mg/cm² Wet Process 5 Pack S02 – Technical Specifications and Handling Considerations – Handling
This electrode sheet comprises a single-sided NCM811 coating on carbon-coated aluminum foil with a coating density of 24 mg/cm² and a compaction density of 3.2 g/cm³. It is intended for lithium-ion battery R&D and requires careful handling to maintain coating integrity and prevent contamination.
- Coating Density: The coating density of 24 mg/cm² defines the active material loading per unit area.
- Active Material Ratio: The active material ratio of 96.5% indicates high purity of the NCM811 formulation.
- Substrate Material: The carbon-coated aluminum foil substrate provides electrical conductivity and current collection.
- Compaction Density: The compaction density of 3.2 g/cm³ influences electrode porosity and electrochemical performance.
- Capacity: The stated capacity of 200 mAh/g represents the specific capacity of the NCM811 material.
How does the 96.5% active material ratio affect the areal capacity and compaction density of this NCM811 electrode?
The 96.5% active material ratio maximizes electrochemical density per unit area. With a coating density of 24 mg/cm² and a specific capacity of 200 mAh/g, the electrode delivers an areal capacity of approximately 4.8 mAh/cm². The compaction density of 3.2 g/cm³ sets the theoretical maximum for calendaring without particle fracture.
What assembly constraints arise from the single-sided coating and carbon-coated aluminum substrate?
The single-sided coating on a 152×100 mm area leaves a 186×100 mm substrate for tab welding, requiring accurate alignment to avoid shorts with double-sided anodes. The carbon-coated aluminum foil, with an areal density of 3.63 mg/cm² and thickness of 12 μm, minimizes contact resistance but is fragile and must be handled in a dry environment to prevent oxidation.
What are the standard electrode activation and storage requirements before cell assembly?
The product notice mandates vacuum baking at 100°C for 12 hours to remove residual moisture from the wet process. No additional activation is specified. The electrode should be stored in a dry room or glovebox to preserve the NCM811 structure and carbon coating integrity.
This NCM811 single-sided cathode offers a 96.5% active material loading on a carbon-coated aluminum substrate with 24 mg/cm² areal density, tailored for Li-ion battery R&D. It requires a 12-hour vacuum bake at 100°C for activation and is restricted to laboratory research only.
Positive
- High active material ratio: The 96.50% active material matrix ensures maximum electrochemical density and accurate data output for benchmarking and characterization.
- Carbon-coated substrate interface: The carbon-coated aluminum foil minimizes contact resistance and supports high-rate cycle capability, enhancing performance consistency.
Trade-offs
- Requires vacuum baking activation: Standard electrode activation requires 12 hours under vacuum baking at 100°C, adding processing time and infrastructure demands.
- Exclusive laboratory use restriction: Sold exclusively for laboratory research, limiting deployment to R&D settings and precluding commercial or production applications.
