Abstract
A measuring element is disclosed for an ion-sensitive solid-contact electrode for measuring ion activity in a measurement medium. An ion-sensitive solid-contact electrode having such a measuring element and an electrochemical sensor having such a solid-contact electrode are also disclosed. The measuring element can include an ion-sensitive layer arranged to contact a measurement medium when in operation, and conductive to lithium ions; and a single-phase electrically conductive layer, which includes metallic lithium or a lithium-(0)-alloy. A solid-state electrolyte layer can be arranged between the ion-sensitive layer and the electrically conductive layer.
