Hydrophilic and Conductive Carbon Nanotube Fibers for High-Performance Lithium-Ion Batteries
Carbon nanotube fiber (CNTF) is a highly conductive and porous platform to grow active materials of lithium-ion batteries (LIB). Here, we prepared SnO<sub>2</sub>@CNTF based on sulfonic acid-functionalized CNTF to be used in LIB anodes without binder, conductive agent, and current collec...

| 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<sub>2</sub>@CNTF based on sulfonic acid-functionalized CNTF to be used in LIB anodes without binder, conductive agent, and current collector. The SnO<sub>2</sub> 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<sub>2</sub>@CNTF with an ideal core–shell structure coated with a thin SnO<sub>2</sub> layer. The specific capacity and rate capability of SnO<sub>2</sub>@-functionalized CNTF were superior to those of SnO<sub>2</sub>@raw CNTF. Since the SnO<sub>2</sub>@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. |
