With the introduction of the "Anode-Free" concept in Li-metal batteries, various studies have been conducted to address the chronic issue of irreversible cycle performance caused by Li dendrite growth. To this end, here we synthesized a Zn-deposited carbon nanofiber (Zn-CNF) composite using thermal shock synthesis to employ as the Li-Metal battery anode. By incorporating Zn as an electrodeposition catalyst, we achieved a remarkably low Li nucleation overpotential, promoting homogeneous Li growth on the CNF substrate and limiting Li dendrite formation. This was confirmed through half-cell and symmetric cell plating-stripping tests and full-cell galvanostatic tests. Furthermore, morphological and chemical analyses, including Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM), were conducted to elucidate the structural and compositional properties of the synthesized materials
