  • Patent number: 11569526
    Abstract: Disclosed are an all-solid-state battery having high energy density and a method for manufacturing the same. One battery structure is pressed instead of pressing each cell unit, an amount of first or second electrode current collectors consumed is reduced, and insulating members are used, thereby simplifying a manufacturing process of the all-solid-state battery and allowing the all-solid-state battery to have high energy density and a stable structure.
    Type: Grant

  • Publication number: 20210159544
    Abstract: The present disclosure relates to an all-solid-state battery with improved lifetime and an operating method thereof. Specifically, the all-solid-state battery includes a laminate including a unit cell provided with an anode, a cathode, and a solid electrolyte layer interposed between the anode and the cathode, and an expansion layer positioned on at least one surface of the laminate, and expanded by at least any one change in voltage and temperature.

  • Publication number: 20200373624
    Abstract: In manufacturing an all-solid-state battery, a cell assembly is pressurized rather than pressurizing each cell unit, and the structure of the battery is simplified by using a reduced number of first electrode current collectors and second electrode current collectors. In particular, the all-solid-state battery includes: first units each including a first electrode current collector and a first electrode active material layer provided on each of opposite surfaces of the first electrode current collector; second units each including a second electrode current collector and a second electrode active material layer provided on each of opposite surfaces of the second electrode current collector; and a solid electrolyte layer disposed between a corresponding first unit and a corresponding second unit.

  • Patent number: 9825325
    Abstract: A rechargeable battery with improved safety and increased capacity of a cell including: an electrode assembly including a first electrode, a second electrode, and a separator between the first and second electrodes; a case comprising an opening configured to receive the electrode assembly; a cap assembly coupled to the sides of the opening of the case; and a lead tab connecting the first electrode to the cap assembly, wherein the first electrode includes a coating region where an active material is coated on both surfaces of a current collector, a first uncoated region where the active material is not coated on the current collector, and a second uncoated region where the active material is not coated on one surface of the current collector.
