摘要： An electrochemical device includes an electrochemical cell, wherein the electrochemical cell including a first anode and a first electrolyte, and a supercapacitor, wherein the supercapacitor including a second anode and a second electrolyte. The electrochemical cell and the supercapacitor are arranged in series and a single cathode shared both by the electrochemical cell and by the supercapacitor, while the first anode and the second anode are connected directly to each other; the single cathode comprises a porous matrix, wherein an active substance belonging to the group of Chalcogens, or group 16, of the Periodic Table of the Elements is infused inside the porous matrix. The electrochemical device is configured to accumulate and deliver simultaneously high levels of both an energy higher than 500 Wh/kg and a power higher than 1,000 W/kg) making a current flow independently into the electrochemical cell or into the supercapacitor depending on energy needs.
