摘要
A method for inspecting a constituent unit cell to be stacked in an all-solid secondary battery of the present disclosure includes (A) measuring an open-circuit voltage between the positive electrode and the negative electrode of a constituent unit cell before a short-circuiting step is performed, (B) temporarily short-circuiting the positive electrode and the negative electrode of the constituent unit cell, (C) measuring an open-circuit voltage between the positive electrode and the negative electrode of the constituent unit cell after a given time has elapsed since the end of step (B), and (D) judging the constituent unit cell to be unusable when the open-circuit voltage measured in step (C) is less than a threshold value. A method for manufacturing an all-solid secondary battery of the present disclosure includes stacking a plurality of constituent unit cells excluding constituent unit cells judged to be unusable by the above inspection method.
