Abstract A novel approach is proposed to address the lithium dendrite penetration issue in solid‐state metal batteries based on garnet‐type electrolyte Li 6.4 La 3 Zr 1.4 Ta 0.6 O 12 (LLZTO). Se and Te nanofilms are deposited LLZTO using a chemical vapor deposition process subsequently reacted with molten situ form tightly‐bonded Li‐LLZTO interface, facilitating interfacial lithium‐ion conduction. Most importantly, constructed 2 Se/Li semiconductor interlayers p ‐type Schottky contact metal, impeding electron injection from electrolyte, resulting dramatical decrease leakage electronic current. Benefiting effective blocking of electrons facilitated conduction, Li|Se‐LLZTO‐Se|Li symmetric cell achieves high critical current density 2.3 mA cm −2 can be stably cycled for over 2000 h at 0.2 .
