摘要： Disclosed is a cathode current collector for an electrical energy storage device and a method for manufacturing the same, which improves adhesion between a current collector and an electrode material and provide a high reaction surface area, thereby improving the performance of the electrical energy storage. In particular, a first alumina film is formed on the surface of an aluminum foil using an anodic oxidation process. Next, the first alumina film formed on a surface of the aluminum foil is removed through etching and a second alumina film is formed on the surface of the aluminum foil, from which the first alumina film is removed, using the anodic oxidation process again. Subsequently, a carbon layer is coated on a surface of the aluminum foil on which the second alumina film is formed.

摘要： An all-solid battery that stably maintains an interface between a solid electrolyte layer and a negative electrode long-term is provided. Specifically, the interface between the solid electrolyte layer and the negative electrode can be stably maintained long-term by using a lithium metal as the negative electrode material and disposing a sacrificial layer between the solid electrolyte layer and the negative electrode so that the negative electrode and the sacrificial layer can form an alloy.

摘要： The present invention relates to a cathode material for a lithium-air battery and a method of manufacturing a cathode using the same. The cathode material of the present invention includes a solvent component and thus includes an electrolyte in a small amount compared to a conventional cathode material, thereby reducing the weight of a cathode manufactured using the cathode material, ultimately increasing the energy density of a lithium-air battery including the cathode.
