How to Read This Configuration
Areal loading, coating side, active-material ratio, collector, and wet or dry process should be read together when selecting an NFPP sheet.
- Areal loading: 13 mg/cm2. Use this value as the coating-mass basis when comparing electrode configurations.
- Active material ratio: 94.50% is the listed active-material fraction of the coating formulation. The actual active mass still depends on the punched electrode mass.
- Compaction density: 1.51 g/cm3 is a physical electrode parameter. Interpret it with loading, thickness, porosity, and the source measurement method.

The NFPP-S03 electrode sheet requires a mandatory vacuum baking step before use to prevent phase contamination and structural degradation. Ambient exposure should be minimized to maintain electrochemical performance integrity.
- Baking Protocol: Bake the electrode sheets under vacuum at 100°C for 12 hours before use.
What is the capacity of the Atomfair NFPP-S03 electrode sheet and how does the active material ratio influence its performance?
The NFPP-S03 electrode sheet delivers a capacity of 95 mAh/g, supported by a high active material ratio of 94.50%. This optimized ratio ensures a robust, uniform NFPP distribution across the coated area, critical for reliable baseline testing and electrolyte validation in sodium-ion battery R&D.
What are the substrate specifications of the NFPP-S03 electrode sheet and how do they affect integration in sodium-ion half-cell testing?
The electrode sheet uses a carbon-coated aluminum foil substrate with a current collector density of 3.63 mg/cm² and a total substrate thickness of 12 + 0.5 + 0.5 μm. The carbon coating maximizes electrical contact and optimizes boundary interfacial dynamics, ensuring consistent electrochemical performance across half-cell foils testing matrices.
What is the recommended pre-treatment protocol for the NFPP-S03 electrode sheet before electrochemical testing?
The recommended baking protocol is to maintain the electrode sheet under vacuum at 100°C for 12 hours. This step prevents ambient phase contamination or structural degradation before thermal validation, ensuring data fidelity in sodium-ion battery R&D experiments.
This single-sided NFPP electrode sheet delivers a 94.5% active material ratio via a 13 mg/cm² wet-coated layer on carbon-coated aluminum foil, ensuring uniform electrochemical testing for sodium-ion battery R&D. A mandatory 12-hour vacuum bake at 100°C is required before use to prevent phase contamination.
Positive
- High active material ratio: 94.50% active material content ensures a homogeneous NFPP distribution across the electrode, reducing variability in half-cell testing.
- Carbon-coated foil substrate: The carbon-coated aluminum foil current collector maximizes electrical contact and interfacial boundary dynamics, enhancing evaluation accuracy.
Trade-offs
- Mandatory vacuum bake before use: The electrode must be baked under vacuum at 100°C for 12 hours to prevent ambient phase contamination or structural degradation, adding preprocessing time to experiments.
