The rewritability of superconductivity is realized in iron‐based superconductors via lithium‐ion insertion and extraction. The superconductivity of FeSe is gradually suppressed with the insertion of lithium ions, and shows a resurgence after the lithium‐ion extraction. This discovery provides a novel way to exploit new applications of superconductivity and a model in searching for the mechanism of high‐ T c superconductivity.
