Abstract

An intermediate layer ensuring good thermal dispersion and intimate interfacial contact between the lithium metal anode (LMA) and solid-state electrolyte (SSE) is essential for improving the interfacial stability and suppressing lithium dendrites, endowing solid-state lithium metal batteries with great potential for practical application. Herein, core–shell Cu@Ag nanowires (NWs) with good lithiophilic affinity and thermal conductivity are applied to stabilize the interface between LMA and garnet-type electrolyte. An intimate anodic interface can be achieved with an interfacial resistance of only 14.14 ohm cm 2 . The lifetime of Li|Li symmetric cells with the Cu@Ag NWs can be prolonged to 1000 h at 0.5 mA cm –2 . The Li|LiFePO 4 full cell delivers a long cycling lifetime over 350 cycles with 90% capacity retention at 1 C. Even with a high-voltage cathode LiNi 0.8 Co 0.1 Mn 0.1 O 2, the full cells can still be stably cycled over 240 cycles at 0.5 C, demonstrating the promising potential for practical application.
