摘要： A lithium air battery comprising a plurality of unit cells which have different diameters, each unit cell comprises: electrodes including: a disc-shaped positive electrode having a first air flow path passing through the positive electrode in a vertical direction of the lithium air battery and one or more electrolyte flow paths on the positive electrode in a horizontal or vertical direction of the lithium air battery; and an negative electrode having a second air flow path passing through the negative electrode in the vertical direction to coincide with the first air flow path; and a separator disposed between the positive electrode and the negative electrode. The unit cells are stacked in the vertical direction within a stack cell tank such that a diffusion layer is disposed between the respective unit cells. A lowermost unit cell has the greatest diameter and diameters of the remaining unit cells, which are sequentially stacked on a lowermost unit cell, gradually decreases vertically in an upward direction so that the unit cells have a stepped structure.

摘要： Disclosed is an anodeless-type all-solid-state battery. The all-solid-state battery includes a plurality of recesses formed in an electrolyte layer and to be depressed from a surface of the electrolyte layer contacting an anode collector and thus serve as spaces for lithium to reversibly precipitate.

摘要： The present disclosure relates to a method of manufacturing a cathode composite for an all-solid-state battery and a method of manufacturing an all-solid-state battery including the same. In particular, the present disclosure relates to a method of manufacturing a cathode composite for an all-solid-state battery in which the cathode composite is manufactured by mixing a solid electrolyte, a conductive material and a cathode active material with a solvent, and then performing two-step vacuum drying, whereby interfacial resistance between the cathode active material, the solid electrolyte and the conductive material is reduced to thus increase ionic conductivity, thereby improving battery performance and capacity, and a method of manufacturing an all-solid-state battery including the same.
