NCM811 / Lithium Metal Dry Pouch Cell with Li-Cu Composite Anode

NCM811 (single-crystal Ni83) cathode paired with a Li-Cu composite lithium-metal anode in a fully assembled, unfilled pouch cell. Designed for custom electrolyte studies, lithium-metal interface research, and controlled cell formation.

Product Name: NCM811 Dry Pouch Cell (0.3Ah)

Cell Type: Lithium Metal Pouch (Unfilled)

Product Code (SKU): AF-BM-C-81LC-03A0-0AF8

Assembly Environment: Dew Point ≤ -40 °C Cleanroom

Description

The NCM811 / Lithium Metal Dry Pouch Cell with Li-Cu Composite Anode is supplied fully stacked and tab-welded but unfilled. This architecture enables researchers to inject custom electrolyte formulations under strictly controlled conditions, evaluating wetting kinetics, SEI/CEI formation, and interfacial impedance without pre-existing solvent interference.

This single/double layer (1/2-layer) configuration couples a high-capacity single-crystal Ni83 cathode (product designation: NCM811) with a precision Li-Cu composite anode, separated by a 12 μm PE + 2 μm ceramic-coated separator. Designed for an operating voltage window of 3.0 V to 4.3 V, all loading levels and geometry dimensions are fully documented for accurate electrochemical modeling.

* Mandatory Notice: Controlled electrolyte injection, hermetic sealing, wetting rest, and standard formation procedures are required prior to galvanostatic cycling.

Target Applications

Electrolyte Formulation Screening: Compare novel liquid, localized high-concentration (LHCE), ionic liquid, or functional additive systems.
Interfacial Characterization: Investigate cathode–electrolyte interphase (CEI) stability and lithium dendrite suppression on Li-Cu substrates.
Formation & Aging Dynamics: Track gas evolution, gassing rate, impedance rise (EIS), and activation kinetics across ambient and elevated temperatures.
Standard Academic Baseline: Serve as an exact, reproducible reference dry cell platform for energy storage publications and thesis benchmarks.

Recommended Activation & Formation Protocol

To form a homogeneous Solid Electrolyte Interphase (SEI) on the Li-Cu composite anode and achieve reproducible cycling, proceed according to the matrix schedule below:

Stage	Procedure	Target Parameter	Cut-off Condition	Rest / Aging
Pre-treatment	Electrolyte Injection & Vacuum Seal	3.0 – 3.5 g/Ah	Chamber Vacuum ≤ -95 kPa	Age at 45 °C for 12 hours (fixture pressure approximately 0.1 MPa)
Formation Step 1	Constant Current Charge (CC)	0.05C (~15 mA)	Cut-off: 3.5 V or 2.0 Hours	Rest 10 Minutes
Formation Step 2	CC-CV Charge & CC Discharge	0.1C (~30 mA)	Charge: 4.3 V (0.02C cut) / Disch: 3.0 V	Rest 10 Minutes between cycles
Secondary Seal	Gas Pocket Puncture & Degassing Seal	Vacuum Degassing	Inert Glovebox Atmosphere	Stabilize at 25 °C for 24 hours before testing

Packaging & Safety Precautions

Atmospheric Exposure Warning: Unfilled cells must remain sealed inside moisture-barrier bags until immediately prior to electrolyte filling. The Li-Cu anode features metallic lithium (20 μm surface cladding) that reacts vigorously with atmospheric moisture above 5 ppm H₂O. Unpack and manipulate strictly inside an Argon-filled glovebox with water and oxygen controlled within the applicable laboratory limits.

Operational Boundaries: Do not subject cells to mechanical deformation, puncture, bending, or temperatures exceeding 60 °C. For professional university and industrial R&D laboratory use only.

Engineering Disclaimer: Values listed above are typical parameters for research reference only. Actual electrochemical cycling performance may vary depending on electrolyte formulation, wetting rest duration, formation protocol, and external fixture pressure.
