Title:
Voltage of the electrochemistry cell based on the art of lithium provided with the internal reference electrode, its manufacturing method, and its anode and cathode, or the simultaneous monitoring method of impedance
Document Type and Number:
Japanese Patent JP5985486
Kind Code:
B2
Abstract:
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.
