PROBLEM TO BE SOLVED: To provide a method for restoring all-solid battery's capacity by supplying lithium ions into an all-solid battery with its capacity decreased.SOLUTION: A method of the present invention is one for restoring a used all-solid battery arranged by laminating a positive electrode current collector layer, a positive electrode active material layer, a solid electrolyte layer, a negative electrode active material layer and a negative electrode current collector layer. The method comprises the step of performing a heat treatment on the all-solid battery in which at least one of the positive electrode active material layer, the solid electrolyte layer, and the negative electrode active material layer includes lithium iodide at a temperature in a range of 110-270°C.SELECTED DRAWING: Figure 1 |
