Swagelok Three-Electrode Battery Test Cell

Overview

The Swagelok Three-Electrode Battery Test Cell is a compact, compression-sealed electrochemical cell designed to evaluate battery and electrode materials under controlled, laboratory-style conditions. A working and counter electrode are compressed in a Swagelok-type geometry, while a dedicated reference electrode port enables true three-electrode measurements (e.g., monitoring cathode potential independently from the full-cell voltage).

Principle of operation

This Swagelok-style architecture compresses the electrode stack within a robust, leak-resistant body. By integrating a reference electrode, researchers can track individual electrode potentials during cycling, diagnose rate limitations, and identify degradation pathways that are otherwise masked in conventional full-cell voltage measurements. This approach is widely recognised as a powerful route to faster, more targeted battery materials development.

Key features and specifications

• Cell material: PEEK (chemically resistant, lightweight, and suitable for many battery electrolytes).
• Electrode core diameter: 6 mm.
• Inner diameter of cell: 10 mm.
• Maximum volume: < 1 mL for electrolyte-efficient testing.
• Reference electrode options (choose one):

                - Ag/AgCl
                - Non-aqueous Ag/Ag+
                - Stainless rod

• Adjustable anode–cathode spacing to minimise distance and tune interfacial conditions.

• Electrode half-cell studies (kinetics, polarisation, impedance)
• Reference-controlled testing of battery materials and electrolytes
• Method development where small electrolyte volume and fast assembly are important
