NCM811 Research Dry Pouch Cell 0.6 Ah 3–4.3 V ATOMFAIR®

This electrolyte-free dry pouch cell is moisture-sensitive and must be stored in a dry environment to prevent electrode degradation prior to electrolyte filling. Handling should be performed in an inert atmosphere glovebox to avoid air exposure of the Li-Cu composite anode and NCM811 cathode.

• Moisture Sensitivity: The unfilled dry pouch cell must be stored under dry conditions to prevent premature electrode reaction with ambient humidity.
• Anode Air Sensitivity: The Li-Cu composite anode may oxidize upon prolonged air exposure, requiring handling in an inert atmosphere glovebox.
• Separator Integrity: The 12 µm PE + 2 µm ceramic separator is mechanically fragile and should not be compressed or folded before cell assembly.

This procedure describes electrolyte filling, vacuum sealing, and initial formation cycling for a 0.6 Ah dry pouch cell. All steps must be performed in an inert atmosphere glovebox to maintain cell integrity.

Required Equipment: Inert atmosphere glovebox (< 0.1 ppm O2 and H2O), Vacuum pouch sealer with temperature control, Electrolyte dispensing syringe (polypropylene), Battery cycler (0.1–1 A range, 3–4.3 V)

1. Transfer dry cell to glovebox
   Transfer the unfilled dry pouch cell into an inert atmosphere glovebox without exposing the electrodes to ambient air.
2. Prepare electrolyte
   Prepare an appropriate lithium-ion electrolyte (e.g., 1 M LiPF6 in EC/DMC 1:1) and degas under vacuum for 5 minutes.
3. Inject electrolyte
   Inject the calculated electrolyte volume (typically 0.3–0.5 mL per layer) into the dry cell through the open seal edge using a polypropylene syringe.
4. Vacuum seal the pouch
   Immediately vacuum-seal the pouch cell at a sealing temperature appropriate for the pouch film, ensuring a final vacuum hold of at least 30 seconds.
5. Perform formation cycle
   Perform a C/10 formation charge step to 4.3 V, hold at 4.3 V until current drops to C/20, then discharge at C/10 to 3 V.

This 0.6 Ah NCM811 dry pouch cell with Li-Cu composite anode and 2/3-layer stack is designed for laboratory electrolyte filling and activation studies, offering a 3–4.3 V window and 220 mAh/g cathode specific capacity, but requires controlled-environment handling due to its electrolyte-free dry state and ceramic-coated separator fragility.

Positive

• High cathode active material loading: The NCM811 cathode uses 97.4% active material with 24 mg/cm² coating areal density and 3.4 g/cc compaction density, enabling high specific capacity (220 mAh/g) for laboratory electrode performance benchmarking.
• Customizable dry pouch format: The electrolyte-free dry pouch cell allows researchers to control electrolyte composition, activation conditions, and electrode finishing, supporting flexible electrochemical evaluation and comparative studies.

Trade-offs

• Requires electrolyte filling and assembly: As a dry pouch cell without electrolyte, it necessitates laboratory infrastructure for electrolyte filling, wetting, and sealing, adding processing steps and potential variability in cell performance.
• Thin ceramic-coated separator fragility: The 12 µm PE + 2 µm ceramic separator is mechanically delicate and may be prone to damage during handling or lamination, requiring careful dry-room or glovebox procedures to maintain integrity.
