How does the double-sided coating at 30 mg/cm² areal loading affect the specific capacity and cycling stability of the NFM111 cathode?

The double-sided coating is designed to provide symmetric ion transport and mechanical integrity, enabling a high specific capacity of 142 mAh/g at an active material ratio of 95.30%. The 30 mg/cm² areal density is paired with a carbon-coated aluminum foil substrate (12 μm foil + 0.5 μm carbon coating on each side) to reduce interfacial resistance, thereby improving cycling stability. This configuration ensures consistent electrochemical performance across the 150 x 110 mm coating area.

What substrate and current collector specifications must be considered when integrating this cathode into a pouch cell design?

The cathode uses a carbon-coated aluminum foil substrate with a total thickness of 13 μm (12 μm foil plus 0.5 μm carbon coating per side) and an areal density of 3.63 mg/cm². The coating area of 150 x 110 mm is offset on a 184 x 110 mm substrate, leaving a 34 mm uncoated margin for tab attachment. The double-sided coating requires symmetrical cell stacking and compatible current collector tabs that can be welded to the carbon-coated aluminum foil.

What infrastructure and preconditioning steps are required before using the NFM111-D06 cathode in electrochemical testing?

The sheets arrive vacuum-sealed and must be baked under vacuum at 100°C for 12 hours to remove residual moisture and solvents, as stated in the product notice. A vacuum oven capable of sustained 100°C operation is mandatory, and handling after baking should occur in an inert atmosphere (e.g., dry room or argon glovebox) to prevent degradation. The 150 x 110 mm coated area and double-sided geometry also require electrode punching and cell assembly equipment compatible with these dimensions.
