LFP Anode-Free Dry Pouch Cell(Multiple Specs)

Name: LFP Anode-Free Pouch Dry Cell (Multiple Specs)

Cell Type: LFP-Anode-Free Pouch Dry Cell

Product Code: XN-LFP-AF

Description:

LFP Anode-Free Pouch Dry Cell pairs lithium iron phosphate (LFP) cathode with a bare copper current collector — no anode active material — in a fully assembled but unfilled (dry) pouch format. As a result, this configuration represents the most aggressive energy-density architecture combined with the inherent safety and long cycle life of LFP chemistry. During the first charge, lithium plates directly from the cathode onto the bare copper foil, eliminating the volume and weight overhead of conventional graphite anodes. Furthermore, the dry (unfilled) pouch format allows customers to inject their own electrolyte formulations, making this cell ideal for advanced anode-free electrolyte and lithium plating interface research targeting next-generation high-safety, high-energy-density battery systems.

Application:

This dry pouch cell serves as a research platform for anode-free LFP battery development, including electrolyte formulation studies for low-voltage lithium plating, plating/stripping interface research on bare copper, advanced electrolyte additive screening for dendrite suppression, full-cell prototyping for stationary energy storage, grid-scale storage, and electric mobility applications, and academic studies of anode-free cell degradation mechanisms (dendrite formation, dead lithium accumulation) under LFP’s safer, lower-voltage chemistry.

LFP + anode-free: maximum safety meets maximum energy density

The combination of LFP (the safest commercial cathode chemistry) with anode-free architecture (the highest theoretical energy density configuration) creates a uniquely valuable research platform. As a result, this cell is well-suited for next-generation stationary storage and electric mobility applications where both safety and energy density are critical design drivers.

In-situ lithium plating from cathode

During the first charge, lithium ions migrate from the LFP cathode and plate directly onto the bare copper current collector, forming the lithium metal anode in-situ. Therefore, customers can study lithium plating morphology under LFP’s lower-voltage operating window (3.7 V vs 4.2 V for NCM systems) — a regime where dendrite suppression and SEI stability differ fundamentally from high-voltage anode-free chemistry.

Stepped formation protocol for low-voltage SEI stability

The recommended formation uses a multi-step current protocol (0.05C → 0.1C across two voltage stages) rather than a single-step charge. Consequently, this gradual approach builds a stable SEI on the freshly plated lithium and on the bare copper edges, reducing first-cycle losses and improving long-term cycling stability — a critical practice unique to LFP anode-free systems.

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 — the core challenges of anode-free chemistry that are most strongly influenced by electrolyte design.

Standardized stacked pouch architecture

Stacked-electrode (laminated) construction with PE 9+3 composite separator. Therefore, results are reproducible across labs and comparable with industry benchmarks for anode-free LFP cells.

Multiple capacity grades + single-layer option

Standard 1 Ah and 2 Ah multi-layer grades support full-cell research. Furthermore, the Single-Layer option provides a simplified platform for fundamental anode-free studies — ideal for SEI characterization on copper, lithium plating morphology imaging, and one-electrode interface research.

Recommended Activation Protocol:

1. Inject electrolyte at 5–6 g per cell. 2. Vacuum-seal the pouch under inert atmosphere. 3. Aging: hold at room temperature for 24 h. 4. Pre-formation rest: 5 minutes. 5. Stage 1: charge at 0.05C for 60 minutes, cutoff 3.4 V (lithium begins plating from cathode onto copper). 6. Rest 3 minutes. 7. Stage 2: charge at 0.1C for 300 minutes, cutoff 3.7 V (full lithium loading). 8. Final aging: hold at room temperature 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. Note that no lithium metal is present in the cell as shipped — anode-free cells in their pre-formation state are significantly less hazardous than pre-deposited lithium-metal cells, but standard lithium-ion cell handling applies once electrolyte is added and formation begins.

Safety:

For research and industrial use only. Once electrolyte is added and formation initiated, lithium metal is plated onto the copper — at this point the cell becomes a lithium-metal battery and must be handled accordingly. Activated cells contain flammable electrolyte and lithium metal; handle in glovebox or dry-room conditions during electrolyte filling and formation. Wear full PPE. Never short-circuit, overcharge, overdischarge, puncture, or expose cells to high temperatures (> 60 °C). Compared to high-voltage anode-free systems, LFP anode-free cells benefit from inherently safer cathode chemistry — but post-formation handling requires the same lithium-metal protocols. 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, applied stack pressure, cycling conditions, and test environment. Anode-free chemistry is highly sensitive to electrolyte design — consult published literature for guidance on electrolyte formulations targeting high coulombic efficiency.
