Three-dimensional (3D) conductive frameworks have been studied extensively in lithium (Li) metal anodes for their good electronic conductivities and superior structural integrity. In this work, we demonstrated a carbon fiber cloth (CFC) framework coated with SnO2 nanoparticles through a hydrothermal process combined with a carbonization method, which served as a reliable host for pouring molten Li to produce a CFC@SnO2@Li composite anode with dendritic suppression and long-life cycling performances. XRD, TEM, HRTEM, XPS and different electrochemical characterizations were carried out. Compared with the routine bare Li||LiFePO4 cells, the CFC@SnO2@Li||LiFePO4 cells had a strong specific ability, excellent rate performance, and stability for a long time, which confirm its great potential as lithium metal anodes in practical battery applications.
