3. Storage & Handling Guidelines
Storage
Keep sealed in a dry, moisture-proof, and light-proof environment (RH ≤ 30%, 15–30 °C).
Avoid contact with strong acids, bases, or volatile solvents.
For long-term storage, seal in argon or dry air atmosphere.
Handling
Open packaging in a dry room or glove box (dew point ≤ –40 °C).
Minimize exposure to air to prevent moisture uptake and surface carbonation.
If moisture absorption occurs, dry under vacuum at 120 °C for 12 h before use.
4. Recommended Slurry & Electrode Fabrication Process
4.1 Cathode Composition (by weight)
VoltXpert® Single-Crystal NCM Powder: 94 wt%
Conductive Carbon (Super P or similar): 3 wt%
Binder (PVDF, dissolved in NMP): 3 wt%
4.2 Slurry Preparation Steps
Dry mix the conductive additive with NCM powder (5–10 min using a high-speed mixer).
Add PVDF/NMP solution (6–8 wt% PVDF concentration) slowly while stirring in the powder blend.
Disperse thoroughly using a planetary vacuum mixer or high-shear mixer for 30–60 min until uniform and smooth.
Adjust slurry viscosity to 8,000–12,000 mPa·s depending on coating requirements.
4.3 Coating & Densification
Coat slurry onto 15–20 µm aluminum foil (single or double side).
Pre-dry at 80 °C with hot air to remove most NMP, then vacuum dry at 120 °C for 12 h.
Roll-press to achieve target compaction density (≥ 3.60 g/cm³).
Cut into required electrode dimensions and assemble in a dry environment.
5. Recommended Electrolytes
Conventional System: LiPF₆ in EC:EMC:DEC (1:1:1, v/v/v) + 1 wt% VC
High-Voltage System: LiPF₆ in FEC:EMC (1:1, v/v) + 2 wt% LiBOB
6. FAQ
Q1: How does single-crystal NCM differ from polycrystalline NCM?
A: Single-crystal particles are mechanically robust, resist cracking during cycling, and are better suited for high-voltage, long-life applications.
Q2: Can it be processed in open air?
A: Not recommended — moisture uptake can lead to surface degradation and performance loss.
Q3: What binder and solvent quality is recommended?
A: Use battery-grade PVDF (e.g., HSV900 or 5130) and high-purity NMP (water content ≤ 50 ppm).
