Abstract (en)
[origin: WO2022002972A1] The invention relates to an electrochemical cell (1), comprising a positive electrode (11) and a negative electrode (12) disposed face to face in the cell body (10), and a stack of electrolytic layers (13, 14, 15) interposed between the positive electrode (11) and the negative electrode (12). The stack of electrolytic layers (13, 14, 15) comprises a first solid electrolyte layer (13) disposed at one end of the positive electrode (11), a second solid electrolyte layer (14) disposed at one end of the negative electrode (12), a layer of composite powder (15) interposed between the first (13) and the second layer (14), the layer of composite powder (15) comprising an electrolyte powder and a powder of electroactive material functioning as a reference electrode of the electrochemical cell.
