High-nickel NCM cathodes are susceptible to moisture and oxygen, necessitating storage in an inert atmosphere (e.g., argon-filled glovebox) to maintain electrochemical performance. Mechanical integrity of the double-side coating depends on avoiding flexural stress and contact with sharp objects.
- Moisture Sensitivity: Exposure to ambient humidity causes lithium hydroxide formation on the particle surface, leading to capacity fade and gas evolution.
- Oxygen Sensitivity: Prolonged air exposure at elevated temperatures can oxidize the nickel content, reducing the reversible capacity of the cathode.
- Coating Adhesion: The electrode coating may delaminate from the carbon-coated aluminum substrate if subjected to rapid thermal cycling or aggressive calendaring.
- Contamination Risk: Foreign particles introduced during handling can cause internal short circuits in assembled cells, requiring cleanroom conditions.
- Electrolyte Compatibility: The cathode is designed for use with carbonate-based electrolytes; contact with acidic or aqueous solvents will degrade the active material.
These steps ensure safe handling and prevent degradation of the high-nickel cathode material prior to cell assembly. Always work in a dry, oxygen-free environment to preserve electrode integrity.
Required Equipment: Argon-filled glovebox (<0.1 ppm H2O, <0.1 ppm O2), Vacuum sealer with desiccant pouch, Ceramic-tipped scissors or precision guillotine, Anti-static tweezers with PTFE tips
- Inspect incoming packaging
Inspect the vacuum-sealed pouch for any puncture or loss of seal before opening to confirm the electrode sheets have not been exposed to ambient air. - Transfer to glovebox antechamber
Transfer the sealed pouch into the glovebox antechamber and perform at least three purge-refill cycles using high-purity argon to eliminate residual oxygen and moisture. - Open pouch inside glovebox
Open the pouch only inside the glovebox main chamber and visually inspect each sheet for wrinkles, tears, or discoloration indicative of degradation. - Cut to desired dimensions
Cut the electrode sheets to the required electrode dimensions using ceramic-tipped scissors, ensuring a clean edge without burrs that could cause short circuits. - Store unused sheets
Store unused cut pieces or full sheets in a sealed container within the glovebox, protected from light and with additional desiccant if long-term storage is planned.
How is the electrode sheet baking time determined?
The electrode sheet is baked under vacuum at 100°C for exactly 12 hours, as specified in the product's standard protocol. This dry time ensures complete removal of residual solvent without degrading the Ni90 active material, which has a 97.4% active material ratio and a compaction density of 3.3 g/cm³.
How does the 57 mg/cm² areal loading of the Ni90 cathode affect rate capability compared to standard loadings?
The high 57 mg/cm² areal loading is optimized for energy density but will reduce rate capability at moderate to high C-rates due to increased ionic transport resistance. To mitigate this, the electrode's 3.3 g/cm³ compaction density and 200 mAh/g capacity provide a baseline; pairing with low-viscosity electrolytes and thin separators is recommended for improved rate performance.
What electrolyte and separator specifications are required for stable cycling of Ni90 double-side coated electrodes?
This Ni90 electrode, coated on 12 μm carbon-coated aluminum foil with an areal density of 3.2 mg/cm², requires a high-voltage-stable electrolyte (e.g., LiPF6 in EC/DMC with FEC additive) to prevent nickel dissolution. The separator must be thermally stable above 100°C and mechanically robust to handle the double-side coating thickness during cell assembly and vacuum baking.
This Ni90 double-side coated cathode sheet delivers a high active material ratio of 97.4% and areal loading of 57 mg/cm², suitable for high-energy lithium-ion battery R&D. However, users must account for the 12-hour vacuum baking requirement and that it is intended for laboratory research only.
Positive
- High active material loading: With a 97.40% active material ratio and 57 mg/cm² double-side coating density, this electrode provides high areal capacity of 200 mAh/g, enabling energy-dense cell testing.
- Customizable electrode parameters: Coating thickness, width, and aluminum foil substrate dimensions can be tailored to user specifications, allowing flexibility for diverse experimental setups and cell formats.
Trade-offs
- 12-hour vacuum baking required: Before use, the electrode sheet must undergo vacuum baking at 100°C for 12 hours to remove residual solvents and moisture, adding preparation time and requiring vacuum oven infrastructure.
- Laboratory research use only: This product is explicitly sold for laboratory research and material evaluation, not for commercial battery manufacturing, which may limit its applicability for scaled-up or production-level testing.
