Ni90 High-Nickel Electrode Sheet 29 mg/cm2 ATOMFAIR®

This high-nickel electrode sheet is highly sensitive to ambient moisture and exposure. Surface degradation or phase contamination may occur if handled outside an anhydrous inert gas environment prior to thermal validation.

• Moisture sensitivity: Containers must be kept tightly sealed or the material must be handled exclusively within an anhydrous inert gas environment to prevent surface degradation.
• Storage constraint: Storage under ambient atmosphere without desiccant or inert gas purge will compromise the electrochemical performance due to lithium hydroxide or carbonate formation.

This procedure describes the safe handling and processing of moisture-sensitive Ni90 electrode sheets for coin cell or pouch cell assembly. All steps must be performed in an inert-atmosphere glovebox with controlled oxygen and moisture levels below 0.1 ppm.

Required Equipment: Argon-filled glovebox, Stainless steel vacuum-compatible transfer vessel, Ceramic scissors or electrode disc punch

1. Transfer into glovebox
   Transfer the sealed shipping container directly into an argon-filled glovebox without intermediate exposure to ambient air.
2. Inspect sheet integrity
   Inspect the electrode sheet for visible cracks, delamination, or discoloration under the glovebox environment before use.
3. Cut electrode discs
   Cut electrode discs of the required diameter using a clean ceramic punch or scissors to avoid metal contamination.
4. Vacuum dry before assembly
   Vacuum-dry the electrode discs at 120 °C for at least 12 hours inside the glovebox antechamber to remove physisorbed moisture.
5. Cool under inert atmosphere
   Allow the dried electrodes to cool to room temperature inside the glovebox before proceeding to cell assembly.

The Atomfair Ni90 high-nickel electrode sheet delivers a specific capacity of 205 mAh/g at 1C with 97.2 wt% active material and a compaction density of 3.4 g/cc, making it suitable for high-energy-density lithium-ion cathode research. However, its extreme moisture sensitivity requires handling exclusively in anhydrous inert gas environments to prevent surface degradation.

Positive

• High specific capacity at 1C: The Ni90 chemistry provides a specific capacity of 205 mAh/g, enabling high-energy-density cathode evaluation in laboratory cell designs.
• Precision areal density control: Strict areal density of 29 mg/cm² ensures reproducible electrochemical data and consistent baseline testing across experimental batches.

Trade-offs

• Extreme moisture sensitivity: The high-nickel content makes the electrode sheet highly sensitive to ambient moisture; containers must be kept sealed or handled exclusively in anhydrous inert gas environments to prevent surface degradation or phase contamination.
• Single-side coating limitation: The electrode is single-side coated on aluminum foil, which may require additional processing steps for full-cell configurations that demand double-side coated electrodes.
