Abstract: An electrode transferring apparatus of a battery cell includes: a transferring body configured to transfer at least one electrode of the battery cell; and an electrode gripper mounted to the transferring body to be vertically movable, the electrode gripper being configured to grip at least one electrode of the battery cell and having a rounded end in contact with the at least one electrode.

Abstract: Provided is a lithium metal secondary battery ensuring electrode-separator adhesive strength and a method for fabricating the same. The lithium metal secondary battery according to the present disclosure includes a negative electrode, a separator and a positive electrode, the negative electrode including a lithium metal foil as a negative electrode material, wherein a nano imprint pattern structure is formed on a lithium metal foil surface which is a surface of the negative electrode facing the separator, and the negative electrode and the separator are adhered to each other.

Abstract: A method for producing a lithium metal negative electrode structure including the steps of: (a) forming a lithium metal layer on a portion of one side or both sides of a current collector, wherein a non-coated portion of the current collector, on which a tab will be formed, is included on one side of the current collector, and wherein a stepped part is present between the non-coated portion of the current collector and the coated portion of the lithium metal layer; (b) coating and curing a photocurable material, or attaching an insulating tape, onto the stepped part between the non-coated portion of the current collector and the coated portion of the lithium metal layer; and (c) punching the result of step (b) into a unit electrode to produce the lithium metal negative electrode structure.

Abstract: Provided is a method for manufacturing an all-solid-state battery which allows a solid electrolyte layer and an electrode to be in sufficiently close in contact with each other without deformation of the electrode shape or damages upon the electrode. The method for manufacturing an all-solid-state battery includes applying slurry for a solid electrolyte layer to the surface of an electrode active material layer to form a patterned solid electrolyte layer, and carrying out pressurization to form a solid electrolyte layer.

Abstract: Disclosed is an apparatus for manufacturing an electrode or a solid electrolyte for an all-solid-state battery. The apparatus for manufacturing an electrode or a solid electrolyte for an all-solid-state battery includes a first roller member configured to press an electrode or a solid electrolyte for an all-solid-state battery, and a second roller member located to be spaced apart from the first roller member to press the electrode or the solid electrolyte for an all-solid-state battery. The first roller member and the second roller member are disposed at opposite locations based on the electrode or the solid electrolyte for an all-solid-state battery.
