316 Stainless Steel Coin Cell Simulator with 25.4mm Outer Diameter and 13mm Inner Diameter for Li-Ion Battery Lab

This specialized test cell is designed for lithium-ion battery research applications. The cell consists of 5 components and is constructed from high-quality materials for reliable laboratory performance.

• Stainless steel sleeve: Outer diameter 25.4mm
• Teflon body: Inner diameter: 13mm
• Material: SS316 stainless steel
• Components: 5 parts

The cell is used in conjunction with an acrylic rack designed to maintain the cell in an upright position during testing. Two rack configurations are available:

• T5 Rack: Holds 5 cells | Dimensions: 500 × 70 × 90 mm
• T8 Rack: Holds 8 cells | Dimensions: 800 × 70 × 90 mm

The cell is placed vertically on the rack during measurement. For optimal performance:

• Add 5-10 drops of electrolyte to wet the electrode and separator
• Wrap cells with para-film after assembly in glove-box for better sealing
• Excess electrolyte will be retained in the cap
• Note: The gap between the steel rod and Teflon body is very small

Working Electrode Preparation: Combine active material (e.g., TiO2 NSHSs), conductive agent (carbon black, Super-P-Li), and polymer binder in 70:20:10 weight ratio. Mix thoroughly and apply to copper foil, then dry in vacuum oven.

Electrode Configuration: Use pure lithium metal as both counter electrode and reference electrode at room temperature.

Cell Assembly Sequence: Place working electrodes first, followed by separator, then lithium metal.

Separator Placement Technique: Stick lithium metal onto separator, wet with electrolyte to ensure adhesion, then place the assembly into the coin cell simulator.
