| Description | Carbon nanotube fiber (CNTF) is a highly conductive and porous platform to grow active materials of lithium-ion batteries (LIB). Here, we prepared $SnO_{2}$@CNTF based on sulfonic acid-functionalized CNTF to be used in LIB anodes without binder, conductive agent, and current collector. The $SnO_{2}$ nanoparticles were grown on the CNTF in an aqueous system without a hydrothermal method. The functionalized CNTF exhibited higher conductivity and effective water infiltration compared to the raw CNTF. Due to the enhanced water infiltration, the functionalized CNTF became $SnO_{2}$@CNTF with an ideal core–shell structure coated with a thin $SnO_{2}$ layer. The specific capacity and rate capability of $SnO_{2}$@-functionalized CNTF were superior to those of $SnO_{2}$@raw CNTF. Since the $SnO_{2}$@CNTF-based anode was free of a binder, conductive agent, and current collector, the specific capacity of the anode studied in this work was higher than that of conventional anodes. |
