Abstract
Disclosed are an all-solid battery and a method of manufacturing the same. The all-solid battery as disclosed herein may include current collectors having the same size for a cathode and an anode, the elongation areas of the cathode and the anode may be controlled due to the ductility of the current collectors during a pressing process. Thus, areas of the anode and the cathode may become different from each other upon the pressing, thus preventing a short-circuit fault from being formed at the edge portion thereof in the pressing process.
Claims6
A method of manufacturing an all-solid battery, comprising:
- forming a cathode layer and an anode layer wherein an area of the cathode layer and an area of the anode are same area;
- stacking the cathode layer and the anode layer;
- disposing an electrolyte layer between the cathode layer and the anode layer;
- pressing the cathode layer, the electrolyte layer and the anode layer, wherein, upon the pressing, the area of the cathode layer is different from the area of the anode layer;
- and
- adhering an auxiliary elongation member having an elongation percentage of at least about 130% of an elongation percentage of the anode layer to a first surface of the anode layer opposite to a second surface that is in contact with the electrolyte layer in order to increase the extent of elongation of the anode layer.
