S4R Sodium Electrode Forming Tool for Coin Cell Spacers
The S4R PTFE Sodium Electrode Forming Tool is designed to form sodium metal directly onto a spacer prior to coin-cell assembly. The tool is manufactured from PTFE and is available for nominal spacer diameters of Ø13 mm, Ø15.5 mm, and Ø15.8 mm.
The selected tool configuration must match the spacer diameter. Preparation and forming must be carried out under a dry inert atmosphere using clean and completely dry components. The tool acts solely as a forming aid and does not regulate or measure the force applied during use.
Due to the softness and tackiness of sodium metal, the formed electrode may adhere to the forming surface. Optional latex release discs are available to facilitate extraction. Their suitability should be assessed according to the laboratory’s contamination and material-compatibility requirements.
