Why is the NP ratio set to 1.15 for this LFP dry pouch cell?
The NP ratio of 1.15 provides a slight excess of anode capacity relative to the cathode, which is standard for LFP cells to prevent lithium plating and improve cycle life. This ratio is supported by the cathode coating areal density of 10 mg/cm² and the anode dimensions of 46.5 × 65 mm, ensuring balanced electrode loading within the 2.5–3.65 V voltage window.
What type of electrolyte is compatible with this dry pouch cell?
This dry pouch cell is electrolyte-free and designed for laboratory electrolyte studies. It accepts standard lithium-ion electrolytes, such as LiPF₆ in carbonate-based solvents (e.g., EC/DMC), which are compatible with the 12 µm PE + 2 µm ceramic separator and the LFP cathode voltage window of 2.5–3.65 V.
What is the anode composition and thickness specification in this cell?
The anode is a Li-Cu composite with a thickness parameter of 20+6+20 µm, indicating a copper current collector with lithium layers deposited on both sides. This architecture, combined with the 46.5 × 65 mm footprint, enables controlled lithium loading for half-cell or prelithiation research within the 14/15-layer stack.
This dry pouch cell with LFP cathode and Li-Cu composite anode (1.1 Ah, 14/15 layers) is supplied electrolyte-free for laboratory research where electrolyte composition and activation protocols must be controlled. The detailed electrode parameters (94% active LFP, 140 mAh/g specific capacity, 2.2 g/cc compaction density) enable systematic comparison, but the unfilled format requires appropriate dry-room or glovebox infrastructure for electrolyte filling and formation cycling.
Positive
- Electrolyte-Free Dry Format for Custom Activation: The cell is supplied without electrolyte, allowing researchers to control electrolyte composition, filling procedure, and formation protocol for investigative studies.
- Detailed Electrode Characterization Provided: The listing specifies cathode active material percentage (94%), specific capacity (140 mAh/g), compaction density (2.2 g/cc), and areal loading (10 mg/cm²), enabling direct comparison with alternative cell configurations.
Trade-offs
- Requires Electrolyte Filling and Formation Infrastructure: As a dry pouch cell, it must be filled with electrolyte and undergo formation cycling before electrochemical evaluation, demanding appropriate dry-room or glovebox facilities.
- Fixed Voltage Window Limits Application Range: The cell's stated voltage window of 2.5 V – 3.65 V is standard for LFP but restricts use in applications requiring higher upper cutoff or deeper discharge.
