Abstract A new and generic strategy to construct interwoven carbon nanotube (CNT) branches on various metal oxide nanostructure arrays (exemplified by $V_{2}O_{3}$ nanoflakes, $Co_{3}O_{4}$ nanowires, $Co_{3}O_{4}–CoTiO_{3}$ composite nanotubes, and ZnO microrods), in order to enhance their electrochemical performance, is demonstrated for the first time. In the second part, the $V_{2}O_{3}/CNTs$ core/branch composite arrays as the host for $Na^{+}$ storage are investigated in detail. This $V_{2}O_{3}/CNTs$ hybrid electrode achieves a reversible charge storage capacity of 612 mAh $g^{−1}$ at 0.1 A $g^{−1}$ and outstanding high-rate cycling stability (a capacity retention of 100% after 6000 cycles at 2 A $g^{−1},$ and 70% after 10 000 cycles at 10 A $g^{−1}).$ Kinetics analysis reveals that the $Na^{+}$ storage is a pseudocapacitive dominating process and the CNTs improve the levels of pseudocapacitive energy by providing a conductive network.
