LFP-Artificial Graphite Anode Dry Pouch Cell(Multiple Specs)

Name: LFP / Artificial Graphite Anode Pouch Dry Pouch Cell (Multiple Specs)

Cell Type: LFP-Graphite Pouch Dry Cell

Product Code: XN-LFP-Gr

Description:

LFP / Artificial Graphite Anode Pouch Dry Pouch Cell pairs lithium iron phosphate (LFP) cathode with high-capacity artificial graphite anode in a fully assembled but unfilled (dry) pouch format. As a result, this configuration delivers the gold-standard LFP/graphite chemistry — the most extensively deployed lithium-ion architecture in stationary energy storage and electric mobility — combined with the dry pouch format that allows custom electrolyte injection. Validated cycling demonstrates 92% capacity retention at 1100+ cycles with excellent rate capability up to 5C (85%+ retention). Furthermore, two-sample reproducibility confirms consistent batch-to-batch performance for reliable research benchmarking.

Application:

This dry pouch cell serves as a versatile research platform for LFP battery development, including electrolyte formulation studies (the cell ships unfilled, allowing customers to inject their own electrolyte), additive screening for LFP/graphite cycle life extension, full-cell prototyping for stationary energy storage, grid-scale storage, electric two-wheelers, light commercial vehicles, and academic studies of LFP/graphite electrochemistry under high-rate cycling.

Characteristics:

Industry-standard 92% retention at 1100+ cycles

Validated cycle testing demonstrates 92% capacity retention through 1100+ cycles, characteristic of mature LFP/graphite chemistry. As a result, this cell delivers a reliable benchmark for long-life battery research, with rich published reference data for additive screening and electrolyte comparison studies.

Excellent rate capability (up to 5C)

The cell maintains 85%+ capacity retention at 5C discharge rate, with smooth rate response from 0.2C through 4C. Therefore, this configuration is well-suited for high-power applications including grid frequency regulation, electric tools, and rapid-discharge stationary storage.

Two-sample reproducibility validated

Performance data from two independent cell samples (LFP-1 and LFP-2) shows nearly perfect overlap across both rate and cycle tests. Consequently, customers receive predictable, reproducible cell behavior — a critical requirement for batch comparison studies and standardized R&D protocols.

Stepped formation protocol for stable SEI

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 graphite, reducing first-cycle losses and improving long-term cycling stability.

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 high-temperature additives, fast-charging electrolytes, and low-temperature performance — critical capabilities for advancing LFP/graphite chemistry beyond standard limits.

Multiple capacity grades + custom specifications

Standard grades cover 1 Ah / 2 Ah. Furthermore, custom capacities, alternative separators, and electrode dimensions are available on request to match specific research requirements.

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. 6. Rest 3 minutes. 7. Stage 2: charge at 0.1C for 300 minutes, cutoff 3.7 V. 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.

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.
