ANTI-SHORT-CIRCUIT SOLID-STATE BATTERY AND PREPARATION METHOD THEREFOR

Provided in the present invention is an anti-short-circuit solid-state battery. The battery comprises several battery cells, each of which is composed of a positive electrode sheet, an insulating ring, a solid-state electrolyte layer and a negative electrode sheet, wherein the positive electrode sheet comprises a positive current collector and a positive coating layer; the negative electrode sheet comprises a negative current collector and a negative coating layer; the length * width * height dimension of an inner ring of the insulating ring is the same as the length * width * height dimension of the positive coating layer; the insulating ring is arranged on the edge of the positive electrode sheet and around the positive electrode sheet, and completely encloses the positive coating layer; and the solid-state electrolyte layer is arranged between the side of the positive electrode sheet on which the positive coating layer is provided and the side of the negative electrode sheet on which the negative coating l
