It is primarily used for measuring the bulk ionic conductivity (perpendicular to the membrane plane) of solid electrolyte membranes such as proton-exchange membranes and ion-exchange membranes, and can also be employed for rapid measurement of the bulk resistivity or conductivity of conventional insulating or conductive thin films. The fixture is made mainly of stainless steel and PEEK, offering resistance to acids, alkalis, and high temperatures. Its electrode leads are positioned on the top of the fixture, enabling in-situ testing in electrolyte solutions (with the fixture placed inside a beaker) or under high-temperature, high-humidity conditions. During the clamping process, the metal electrodes move only vertically without rotating, thereby preventing damage to the membrane. Operation is straightforward: after cutting the membrane to size, place it into the fixture, tighten the knob to ensure proper contact—alternatively, a torque wrench can be used for precise pressure control—and then measure the membrane’s conductivity using the AC impedance spectroscopy (EIS) method.
Suitable for testing the cathode, anode, and separator performance of lithium, sodium, and potassium batteries; excellent sealing.
A specialized electrolytic cell compatible with synchrotron radiation facilities, integrating a three-electrode electrochemical system and an X-ray‑transmissive window, enables simultaneous CV and potentiostatic electrolysis while concurrently acquiring XRD, XAFS (XANES/EXAFS), and SAXS data, thereby enabling real-time, in situ monitoring of the catalyst’s crystalline phase, oxidation state, and coordination environment during electrocatalytic processes.
The EC-PEN electrochemical corrosion test pen is a sensor for conducting electrochemical corrosion tests under real‑world conditions. It enables on‑site electrochemical measurements, allowing users to obtain critical information about corrosion rates. Equipped with integrated electrodes and an electrolyte, the EC-PEN is both portable and easy to use. It can be brought into contact with test specimens of any shape or size, facilitating rapid assessment of localized corrosion. The device incorporates an electrolyte reservoir that immerses an Ag/AgCl reference electrode and a Pt wire counter electrode. During measurement, the EC-PEN’s tip—fitted with a porous membrane—is positioned at the target location on the component; the electrolyte then flows out of the tip, wetting the local surface. With minimal preparation, electrochemical corrosion testing of samples can be performed quickly. Thanks to its portability, straightforward sample preparation, and lack of stringent requirements for the test specimen, the EC-PEN opens up new possibilities for in‑situ, nondestructive corrosion monitoring. The EC-PEN is maintenance‑free and typically supports approximately 200 to 500 measurements, with a tip‑contact area of 1.5 mm².
