The present invention relates to a lamination apparatus for a secondary battery, which thermally bonds an electrode assembly in which electrodes and separators are alternately stacked, the lamination apparatus comprising: a transfer member to transfer the electrode assembly; a support member to support each of top and bottom surfaces of the electrode assembly transferred by the transfer member; a heating member disposed outside the support member to heat the electrode assembly supported by the support member; and a moving member to move the heating member in a direction away from the electrode assembly.

An all-solid battery includes a multilayer structure that includes pairs of positive electrode layers and pairs of negative electrode layers, first solid electrolyte layers, second solid electrolyte layers, and third solid electrolyte layers, the pairs of positive electrode layers and the pairs of negative electrode layers being alternately stacked, each of the first solid electrolyte layers being interposed between each of the pairs of positive electrode layers, each of the second solid electrolyte layers being interposed between each of the pairs of negative electrode layers, each of the third solid electrolyte layers being interposed between the positive electrode layer and the negative electrode layer, wherein a thickness of the third solid electrolyte layer is different from at least one of a thickness of the first electrolyte layer and a thickness of the second electrolyte layer.

An all-solid-state battery manufacturing apparatus disclosed herein includes a transport apparatus, a press roller, and an adhesive provision apparatus. The transport apparatus transports an active material layer. The press roller has a foil attachment surface, which is a cylindrical surface to which the current collection foil is to be attached. The press roller rotates and moves the current collection foil attached to the foil attachment surface to the surface of the active material layer being transported by the transport apparatus and presses the current collection foil and the active material layer between the press roller and the transport apparatus. The adhesive provision apparatus is provided on a movement path of the current collection foil rotated and moved by the foil attachment surface of the press roller, and provides an adhesive to the current collection foil attached to the press roller.

The present disclosure provides a battery. The battery includes a separation structure having a resistance greater than a resistance threshold; a positive electrode of the battery and a negative electrode of the battery disposed on two sides of the separation structure; a liquid conductor configured to transport conductive ions between the positive electrode and the negative electrode; a storage structure configured to store supplementary material to release into the liquid conductor; and an enclosure configured to form an enclosed cavity to accommodate the separation structure, the positive electrode, the negative electrode, the liquid conductor, and the storage structure.

A method including providing, on a substrate, first and second stacks for an energy storage device with a groove therebetween is provided. The first and second stacks each, respectively, include a first electrode layer on the substrate, an electrolyte layer on the first electrode layer, and a second electrode layer on the electrolyte layer. A first material is deposited within the groove and a second material is deposited over the first stack, the first material and the second stack to electrically connect the second electrode layers of the first and second stacks, via the second material. The first material prevents the second material from contacting the first electrode layer of the first and second stacks and the electrolyte layer of the first and second stacks, to electrically insulate the first electrode layer of the first and second stacks and the electrolyte layer of the first and second stacks from the second material.
