  "textContent": "The present invention is directed to an electrochemical cell based on lithium technology, comprising the following components - a positive electrode containing a cathode material, - a separator made of an electrically insulating material, - a negative electrode containing an anode material, - a liquid and/or solid ion conductor material for transportation of lithium ions between the positive and the negative electrode, the said components being sealed within a casing, wherein the positive electrode and the negative electrode each comprise an electrically conducting structure extending through a wall of the casing for further electrical connection, characterized in that it further comprises: - a reference electrode which is electrically insulated from the positive and the negative electrodes, comprising at least one non-metallic lithium compound within the said casing, and an electrically conducting structure being in electrical contact with the said reference electrode, the electrically conducting structure extending through a wall of the casing for further electrical connection. The invention is further directed to a method for the preparation of this electrochemical cell, to a method for measuring the voltage or the impedance of a cathode and/or of an anode of such an electrochemical cell based on lithium technology, and to driving methods of said cell, decreasing aging phenomena and improving its life duration.",
