A type of small electrode for basic studies on metal alloy powder materials for metal-hydride anodes has been proposed. The electrode holds a few milligrams of the active material and contains no inert binder material admixed to the active material. The electrode is prepared simply in a laboratory mechanical press. It was shown using cyclic voltammetry and electrochemical impedance spectroscopy that the electrode exhibits features of single-particle electrodes. Thus, it is suitable for a direct determination of performance parameters characteristic of the active particles without the need to resort to a complicated porous-electrode modeling.
