The development of solid-state lithium metal batteries (SSLBs) faces challenges like high interfacial resistance, volume fluctuations, and lithium dendrite growth. This work employs a template method to in situ construct a three-dimensional (3D) metallic nanonetwork with mixed ionic/electronic conductivity (MIEC) on Ta-doped LLZTO solid electrolyte. This structure not only remains stably anchored at the LLZTO interface but also exhibits excellent electronic conductivity, enabling a more uniform electron distribution across the heterogeneous interface. Benefiting from this interfacial design, the lithium symmetric cells achieve a high critical current density (CCD) of 1.5 mA cm-2 and stable cycling for 3000 h at 0.5 mA cm-2 and maintain robust performance for more than 100 h at 1.0 mA cm-2. The assembled full cells exhibit exceptional electrochemical performance, and this method provides a paradigm for interfacial structural design in SSLBs.
