NCM90 Silicon-Carbon Anode Pouch Dry Pouch Cell (Multiple Specs)

Name: NCM90 / Silicon-Carbon Anode Pouch Dry Pouch Cell (Multiple Specs)

Cell Type: NCM90-700 Silicon-Carbon Pouch Dry Cell

Product Code: XN-NCM90-SiC

Description:

NCM90 / Silicon-Carbon Anode Pouch Dry Pouch Cell pairs high-nickel NCM90 (Ni90) cathode with a high-silicon-content silicon-carbon composite anode, delivering high energy density up to 360 Wh/kg in a fully assembled but unfilled (dry) pouch format. As a result, this dry cell is ideal for electrolyte filling experiments, advanced lithium battery R&D, and energy density benchmarking. The 23.5% silicon content in the anode provides 700 mAh/g specific capacity — significantly higher than conventional graphite — while validated cycling performance exceeds 640 cycles at > 90% capacity retention. Furthermore, multiple capacity grades (1 Ah / 2 Ah / 5 Ah / 14.5 Ah) and custom specifications are available to support varied research needs.

Application:

This dry pouch cell serves as a research platform for high-energy-density lithium battery development, including electrolyte formulation studies (the cell ships unfilled, allowing customers to inject their own electrolyte), high-nickel cathode performance evaluation, silicon-carbon anode degradation studies, and full-cell prototyping for next-generation 350+ Wh/kg battery systems. Furthermore, the standardized pouch format simplifies comparison with industry benchmarks.

Cycle Life Performance:

Cycle life performance of NCM90 / silicon-carbon pouch cells (3 sample lots: Y243-B107-3, Y243-B108-1, Y243-B108-3). All cells maintain > 90% capacity retention after 640+ cycles, demonstrating excellent cycling stability for high-silicon anode systems.

Characteristics:

High-energy-density chemistry (up to 360 Wh/kg)

The NCM90 cathode (200 mAh/g) paired with high-silicon (23.5% Si) anode (700 mAh/g) enables cell-level energy density up to 360 Wh/kg in the 14.5 Ah grade — significantly above conventional NCM811/graphite designs. As a result, this combination supports research targeting next-generation EV and aviation battery requirements.

Validated 640+ cycle life

Despite the high silicon content (which typically challenges cycle life), three independent lots maintain > 90% capacity retention through 640+ cycles. Therefore, customers receive a research platform with both high energy density and proven cycling stability — a combination rarely available together in high-Si systems.

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 high-Ni / high-Si chemistry — a critical capability for advanced battery R&D programs.

Multiple capacity grades + custom specifications

Standard grades cover 1 Ah / 2 Ah / 5 Ah / 14.5 Ah. Furthermore, custom specifications including alternative separators, electrode dimensions, and capacity targets are available on request to match specific research requirements.

Standardized stacked pouch architecture

Stacked-electrode (laminated) construction with standardized electrolyte filling protocol (3–4 g/Ah), formation (0.1C to 4.2 V), and aging (45 °C × 12 h on fixture, then 24 h room temperature). Therefore, results are reproducible across labs and comparable with industry benchmarks.

Recommended Activation Protocol:

1. Inject electrolyte at 3–4 g/Ah ratio. 2. Vacuum-seal the pouch under inert atmosphere. 3. Aging: hold at 45 °C on fixture for 12 h. 4. Formation: charge at 0.1C to 4.2 V. 5. 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.

Safety:

For research and industrial use only. Activated lithium-ion cells contain flammable electrolyte and high-energy electrode materials. Wear PPE during cell handling and electrolyte filling. Never short-circuit, overcharge, overdischarge, puncture, or expose cells to high temperatures (> 60 °C). Refer to SDS for complete safety information.
