MANUFACTURING METHOD OF ALL SOLID STATE LITHIUM SECONDARY BATTERIES WITH EMBEDDED REFERENCE ELECTRODE IN SOLID ELECTROLYTE AND THE ITS THEREOF

摘要

The present invention relates to a manufacturing method of an all-solid lithium secondary battery with an embedded reference electrode and an all-solid lithium secondary battery for a reference electrode to be inserted and, more specifically to a manufacturing method of an all-solid lithium secondary battery with an embedded reference electrode, capable of grasping how much the entire cell voltage loss is affected by characteristic change (degradation) in a certain electrode/electrolyte interface, through grasping resistance change of each electrode/electrolyte; and to an all-solid lithium secondary battery for a reference electrode to be inserted. The present invention comprises the steps of: combining the anode on the upper side of a lower electrode rod while an upper mold having an upper electrode rod in the central part and a lower mold having the lower electrode rod in the central part are separated; combining a first solid electrolyte on the upper side of the anode while including a paste which connects and fixes an electric wire on the upper side as a reference electrode; exposing one end of the electric wire to the outside of the upper and lower molds and compressing the other end to be fixed on the paste; mounting a second solid electrolyte and the cathode on the upper part of the first solid electrolyte to cover the electric wire; compressing the second solid electrolyte and the cathode through the upper electrode rod in the upper part of the cathode; removing the upper and lower molds; and combining current collecting units with the anode and the cathode, respectively.
