LFP-Lithium Metal Pouch Battery Dry Pouch Cell(Unfilled)(Multiple Specs)

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

Cell Type: LFP-Li Pouch Dry Cell

Product Code: XN-LFP-Li

Description:

LFP / Lithium Metal Pouch Battery Dry Pouch Cell pairs lithium iron phosphate (LFP) cathode with a Li-Cu composite lithium metal anode in a fully assembled but unfilled (dry) pouch format. As a result, this configuration combines the intrinsic safety and ultra-long cycle life of LFP chemistry with the high-energy-density advantage of lithium metal anode — a uniquely valuable combination for long-life, high-safety battery research. Validated cycling demonstrates exceptional performance: 100% capacity retention at 500 cycles in the standard test, and 1500+ cycles in extended long-term testing, with rate capability from 0.5C through 5C. Furthermore, the dry (unfilled) pouch format allows customers to inject their own electrolyte formulations for advanced LFP+Li metal interface research.

Application:

This dry pouch cell serves as a research platform for long-life lithium metal battery development, including electrolyte formulation studies for Li-metal anodes, LFP cathode performance evaluation in Li-metal systems, lithium plating/stripping interface research at low voltage, full-cell prototyping for stationary energy storage, grid storage, electric tools, and aerospace applications, and academic studies of LFP/Li-metal long-cycle electrochemistry.

Available Capacity Grades:

Cycle Life Performance — 500-Cycle Validation:

LFP‖Li pouch cell (cathode 15 mg/cm², anode 20 μm Li/Cu, 2.5–3.7 V, 0.2C charge / 1C discharge). Capacity retention 100% at 500 cycles with coulombic efficiency consistently at 100% — exceptional performance for a lithium metal system.

Cycle Life Performance — 1500+ Cycle Long-Term Test:

LFP-Li 1000 mAh pouch cell at 25 °C, 0.2C charge / 1C discharge. Over 1500 cycles validated with stable discharge capacity, demonstrating extreme long-cycle-life capability — uniquely matched to grid storage and stationary energy applications.

Rate Performance:

Rate performance test on LFP-Li 500 mAh cell at 25 °C. Capacity retention from 0.5C through 3C remains above 88%, with 83% retained at 5C. Full capacity recovery upon return to 0.5C confirms rate-limited (not damaged) behavior.

Characteristics:

Industry-leading 1500+ cycle life with lithium metal

Validated long-term cycling demonstrates 1500+ cycles in the LFP+Li metal configuration — a remarkable result, as lithium metal systems typically show rapid degradation from dendrite formation and SEI instability. As a result, this cell delivers a research platform that combines the long-life advantages of LFP chemistry with the high-energy-density potential of lithium metal anode.

100% capacity retention at 500 cycles

In standard 500-cycle testing, the cell maintains 100% capacity retention with coulombic efficiency consistently at 100%. Therefore, customers receive a stable, reproducible baseline for short-term cycling studies, additive screening, and electrolyte comparison work.

Excellent rate capability (0.5C through 5C)

The cell maintains over 88% capacity retention from 0.5C through 3C discharge rates, with 83% retained at 5C. Moreover, full capacity recovery upon return to 0.5C confirms that 5C drop is rate-limited rather than damage-induced. Consequently, this configuration supports research into power-density-sensitive applications.

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. Therefore, customers can inject their own electrolyte formulations to study electrolyte effects on lithium plating efficiency at low voltage, SEI stability, and dendrite suppression — critical capabilities for advanced LFP+Li metal battery R&D.

Multiple capacity grades + custom specifications

Standard grades cover 0.5 Ah / 1 Ah / 2 Ah. Furthermore, custom lithium metal thickness, alternative separators, 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 room temperature for 12 h under fixture clamping. 4. Formation step 1: charge at 0.1C constant current to 3.7 V. 5. Rest 10 minutes. 6. Discharge at 0.1C constant current to 2.5 V. 7. Rest 10 minutes. 8. Formation step 2: charge at 0.1C constant current to 3.7 V. 9. Rest 10 minutes. 10. Discharge at 0.1C constant current to 2.5 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.
