This document outlines the critical handling and drying constraints for the Atomfair NFPP-S02 electrode sheet to ensure material integrity and reliable electrochemical testing. Adherence to the specified vacuum baking protocol is mandatory to prevent ambient phase contamination and structural degradation.
- Vacuum Baking Protocol: Bake the electrode sheet under vacuum at 100°C for 12 hours before thermal validation to prevent ambient phase contamination or structural degradation.
What is the active material ratio and specific capacity of the Atomfair NFPP-S02 sodium iron phosphate pyrophosphate electrode sheet?
The NFPP-S02 electrode sheet features an active material ratio of 94.50% and a specific capacity of 95 mAh/g. These parameters are specified in the product's technical specifications, ensuring high material purity and reliable electrochemical performance for sodium-ion battery R&D.
What vacuum baking conditions are required for the NFPP-S02 electrode sheet before use?
The recommended baking protocol is 12 hours under vacuum at 100°C. This step is critical to prevent ambient phase contamination or structural degradation prior to thermal validation, as stated in the product's operational notice.
What type of current collector substrate is used in the Atomfair NFPP-S02 electrode sheet?
The electrode sheet uses a carbon-coated aluminum foil substrate with a current collector density of 3.3 mg/cm² and a total substrate thickness of 12 + 0.5 + 0.5 μm. This carbon coating is designed to maximize electrical contact and optimize boundary interfacial dynamics in half-cell testing.
Atomfair NFPP-S02 electrode sheet provides a single-side coated sodium iron phosphate pyrophosphate cathode with 95 mAh/g capacity and 94.5% active material ratio on carbon-coated aluminum foil, designed for sodium-ion battery R&D with precise wet coating and a mandatory 12-hour vacuum baking step at 100°C.
Positive
- High active material ratio: The 94.5% active material ratio ensures a homogeneous NFPP distribution across the electrode, critical for reliable half-cell testing and baseline performance comparisons.
- Carbon-coated aluminum foil substrate: The carbon-coated aluminum current collector maximizes electrical contact and optimizes interfacial dynamics, enhancing measurement accuracy in electrochemical evaluations.
Trade-offs
- Mandatory vacuum baking protocol: The electrode sheets require a 12-hour vacuum bake at 100°C prior to use to prevent ambient phase contamination and structural degradation, adding preprocessing time and infrastructure demands.
- Single-sided coating limitation: The single-side coating design restricts areal loading to one side, which may require additional lamination or assembly steps for full-cell configurations that typically use double-sided electrodes.
