\begin{document}$ T_{z}=-2 $\end{document} drip-line nucleus \begin{document}$ ^{22} $\end{document}Al is measured for the first time as \begin{document}$ 18103(10) $\end{document} keV using the newly-developed Bρ-defined isochronous mass spectrometry method at the cooler storage ring in Lanzhou. The new mass excess value allowed us to determine the excitation energies of the two low-lying \begin{document}$ 1^+ $\end{document} states in \begin{document}$ ^{22} $\end{document}Al with significantly reduced uncertainties of 51 keV. When compared to the analogue states in its mirror nucleus \begin{document}$ ^{22} $\end{document}F, the mirror energy differences of the two \begin{document}$ 1^+ $\end{document} states in the \begin{document}$ ^{22} $\end{document}Al-\begin{document}$ ^{22} $\end{document}F mirror pair are determined to be \begin{document}$ -625(51) $\end{document} keV and \begin{document}$ -330(51) $\end{document} keV. The excitation energies and mirror energy differences are used to test the state-of-the-art ab initio valence-space in-medium similarity renormalization group calculations with four sets of interactions derived from the chiral effective field theory. The mechanism leading to the large mirror energy differences is investigated and attributed to the occupation of the \begin{document}$ \pi s_{1/2} $\end{document} orbital."> Ground-state mass of <sup>22</sup>Al and test of state-of-the-art <i>ab initio</i> calculations -
