  • Patent number: 10177368
    Abstract: An anode compartment for rechargeable lithium or sodium batteries, including: a solid electrolyte; a collector deposited on the solid electrolyte; and an active material made of lithium metal or sodium metal which has been grown between the solid electrolyte and the collector in order to form an electrode made of lithium metal or sodium metal with the collector, in which the collector is made of an amorphous alloy. A method for manufacturing such an anode compartment and a battery including said anode compartment is also presented.
    Type: Grant

  • Patent number: 9236642
    Abstract: The present invention relates to a precursor of a negative electrode compartment for rechargeable metal-air batteries, comprising a rigid casing (1), at least one solid electrolyte membrane (2), a protective covering (5), completely covering the inside face of the solid electrolyte membrane (2), a metallic current collector (3) applied against the inside face of the protective covering (5), preferably also a block (4) of elastic material applied against the current collector and essentially filling the entire internal space defined by the walls of the rigid casing and the solid electrolyte (2), and a flexible electronic conductor (6) passing in a sealed manner through one of the walls of the rigid casing. The present invention also relates to a negative electrode compartment having a rigid casing obtained from said precursor and to a battery containing such a negative electrode compartment.
