Here, we have developed a failure mechanism map of ultrathin Zn metal anodes in practical large (49 cm<sup>2</sup>) pouch cells and divided it into three zones, i.e., polarization, short-circuiting, and transition between the two. The correlation between failure mode and depth of discharge was revealed. Moreover, to improve the durability of large Zn anodes, a molecular interfacial layer was designed to produce compact epitaxial growth of Zn. Consequently, practical Zn||I<sub>2</sub> pouch cells with modified Zn anodes had a high capacity (∼1,200 mAh) and cycling stability (∼600 cycles), which is the record-stable Ah-level full cell reported so far.

Here, we report a facile strategy to concomitantly induce (100)-oriented perovskite and improve buried interface by incorporating a bifunctional ligand 2-(methylthio) ethylamine hydrochloride (METEAM) into perovskite precursor solution. METEAM molecules preferentially adsorb on (100) facets of perovskite via strong interactions with perovskite lattice to induce oriented perovskite crystallization.

As-prepared perovskite films exhibit suitable energy level and high mobility for interfacial charge transfer, low trap state density, and long carrier lifetime.
