Abstract (en)

[origin: WO2021122606A1] The present invention relates to an electric electrochemical cell (10), characterized in that it comprises a casing (12) that comprises a vessel (14), the internal surface of which is at least partially covered by a layer (15) of copper so as to form a current collector for the negative electrode (60) and an upper cover (18), which houses a three-dimensional positive electrode (+) structure and which contains a solid electrolyte, and in that the three-dimensional positive electrode structure comprises a series of positive electrodes (50), each of which is a vertical bar (50).
