NCM811 / Lithium Metal Pouch Battery Dry Pouch Cell (Unfilled)(Multiple Specs)

Name: NCM811 / Lithium Metal Pouch Battery Dry Pouch Cell (Unfilled) (Multiple Specs)

Cell Type: NCM811-Li Pouch Dry Cell

Product Code: XN-NCM811-Li

Description:

NCM811 / Lithium Metal Pouch Battery Dry Pouch Cell pairs high-nickel NCM811 (Ni80) cathode with a Li-Cu composite lithium metal anode in a fully assembled but unfilled (dry) pouch format. As a result, this configuration enables high-energy-density research targeting next-generation 350+ Wh/kg lithium-metal battery systems. The cell uses 20 μm single-side lithium metal on an 8 μm copper current collector, paired with NCM811 cathode delivering 200 mAh/g specific capacity at 97.0% active material content. Validated cycling performance demonstrates 400+ cycles at near-100% capacity retention in the 4.2 V window, along with excellent rate capability up to 3C. Furthermore, the dry (unfilled) pouch format allows customers to inject their own electrolyte formulations, making this cell ideal for advanced lithium-metal electrolyte and interface research.

Application:

This dry pouch cell serves as a research platform for lithium-metal battery development, including electrolyte formulation studies for Li-metal anodes, NCM811 cathode performance evaluation in Li-metal systems, lithium plating/stripping interface research, full-cell prototyping for high-energy-density applications (UAV, drone, eVTOL, advanced EV), and academic studies of lithium-metal anode degradation mechanisms.

First-Cycle Charge–Discharge Curve:

First-cycle charge–discharge curve of NCM811-Li pouch cell. Discharge capacity reaches ~1170 mAh in the 3.0–4.4 V voltage window, exceeding the 1000 mAh design capacity by ~17%.

Cycle Life Performance:

(Left) High-voltage 4.4–3.0 V cycling at 0.2C/0.5C, 1200 mAh cell — 100+ cycles at 25 °C. (Right) Standard 4.2–3.0 V cycling at 0.2C/1C, 1000 mAh cell — 400+ cycles at near-100% capacity retention, demonstrating excellent stability for high-energy lithium-metal applications.

Rate Performance:

Rate performance test on a 300 mAh NCM811-Li cell at 25 °C. The cell maintains high capacity retention from 0.5C through 3C discharge rates, with significant capacity drop at 5C. Returning to 0.5C fully recovers original capacity, confirming rate-limited (not damaged) behavior.

Characteristics:

Validated 400+ cycle life at near-100% retention

In the standard 3.0–4.2 V window with 0.2C charge / 1C discharge, the cell delivers 400+ cycles with capacity retention close to 100% — a remarkable performance for high-nickel/lithium-metal chemistry. As a result, this configuration provides researchers with a stable, reproducible platform for long-term cycling studies.

High energy density potential

The combination of high-nickel NCM811 cathode (200 mAh/g) and lithium metal anode (theoretical 3860 mAh/g) enables cell-level energy density well above conventional NCM/graphite designs. Therefore, this configuration is a leading research platform for next-generation 350+ Wh/kg battery systems targeting UAV, drone, eVTOL, and advanced EV applications.

Excellent rate capability (up to 3C)

The cell delivers high capacity retention from 0.5C through 3C discharge rates. Consequently, customers can study power-density-sensitive applications (rapid pulse discharge, high-rate cycling) without redesigning the cell architecture.

Pre-deposited Li-Cu composite anode

20 μm single-side lithium metal pre-deposited on 8 μm copper current collector eliminates the need for in-cell lithium plating during formation. Therefore, customers receive a ready-to-fill cell with controlled lithium loading, simplifying experimental setup and improving reproducibility.

Dry (unfilled) pouch design for electrolyte studies

The cell ships fully assembled but without electrolyte. Consequently, customers can inject their own electrolyte formulations to study electrolyte effects on lithium plating/stripping, SEI formation, and high-Ni cathode interface — critical capabilities for advanced lithium-metal battery R&D.

Multiple capacity grades + custom specifications

Standard grades cover 1 Ah / 2 Ah / 5 Ah. Furthermore, custom lithium metal thickness, alternative separators, voltage windows (4.2 V or 4.4 V), and electrode dimensions are available on request to match specific research requirements.

Recommended Activation Protocol:

1. Inject electrolyte at 3 g/Ah ratio. 2. Vacuum-seal the pouch under inert atmosphere. 3. Aging: hold at 45 °C on fixture for 12 h. 4. Formation step 1: charge at 0.1C constant current to 4.2 V. 5. Rest 10 minutes. 6. Discharge at 0.1C constant current to 3.0 V. 7. Rest 10 minutes. 8. Formation step 2: charge at 0.1C constant current to 4.2 V. 9. Rest 10 minutes. 10. Discharge at 0.1C constant current to 3.0 V. 11. Final seal. 12. Room-temperature aging: rest for 24 h before subsequent cycling tests.

Packaging & Storage:

Cells ship vacuum-sealed under inert atmosphere in moisture-barrier packaging. Therefore, customers should store sealed in a cool, dry environment, protected from moisture. Open packaging in a dry-room or glovebox environment immediately before electrolyte filling. Lithium metal anodes are extremely sensitive to moisture and oxygen — handle exclusively in glovebox conditions (H₂O and O₂ < 50 ppm).

Safety:

For research and industrial use only. Lithium metal is highly reactive — it ignites on contact with water and reacts with air over time. Activated lithium-metal cells contain flammable electrolyte and high-energy electrode materials. Handle exclusively in glovebox or dry-room conditions during cell preparation and electrolyte filling. Wear full PPE. Never short-circuit, overcharge, overdischarge, puncture, or expose cells to high temperatures (> 60 °C). Refer to SDS for complete safety information.

Note: Values listed above are typical and for reference only. Performance may vary depending on electrolyte choice, formation protocol, cycling conditions, and test environment.
