  • Process for manufacturing an alkaline-based hybrid supercapacitor type battery, battery obtained by this process and process for recycling an anode material of an alkali-ion battery
    Patent number: 10249447
    Abstract: A process is provided for manufacturing an alkaline-based hybrid supercapacitor type battery, to an alkaline-based hybrid supercapacitor type battery, and to a process for recycling a negative electrode of an alkali-ion battery. The process for manufacturing the alkaline-based hybrid supercapacitor type battery comprises forming a negative electrode A from an electrode material B originating from a used alkali-ion battery having lost at least some of its initial capacity. Embodiments of the present disclosure are in particular applicable to the field of batteries.

  • Electrochemical supercapacitor device made from an electrolyte comprising, as a conductive salt, at least one salt made from an alkali element other than lithium
    Patent number: 9773620
    Abstract: The invention relates to a device of the hybrid supercapacitor type comprising at least one cell comprising: a porous positive electrode comprising activated carbon; a negative electrode comprising a carbonaceous material capable of inserting an alkaline element other than lithium, this carbonaceous material being different from the activated carbon used at the positive electrode; and a non-aqueous electrolyte comprising a salt selected from salts of an alkaline metal other than lithium.
