Superior Sodium Metal Anodes Enabled by 3D Hierarchical Metallic Scaffolds with Enhanced Sodiophilicity.

ABSTRACT: Sodium-metal batteries (SMBs) are regarded as key for next-generation energy storage due to their high theoretical energy and potential cost effectiveness. However, Na-metal systems remain challenging by critical barriers, including severe Na dendrites growth and infinite huge volume change, which limit the feasibility of SMBs. Here, this work develops a 3D conductive scaffold consisting of vertical crystalline TiO₂ nanotube arrays embedded with ultrafine silver nanoparticles (denoted as Ag@TiO₂ NTAs) with ultrasonication-assisted in situ deposition method for high-performance SMBs. Significantly, the hierarchical hollow nanotubes with large surface area can reduce the current density to promote compact electrodeposition and guide the parallel growth of Na. Meanwhile,
