The ever-presenting challenges of poor electrical conductivity, sluggish lithium-ion transmission, and unstable structure block the applications of high-energy V6O13 in practical lithium-ion batteries (LIBs). Herein, reduced graphene oxide-modified V6O13 (V6O13@rGO) nanostructure hybrids with high electrical conductivity and stable structure were in-situ manufactured using a facile hydrothermal route. The incorporation of rGO lamina into the V6O13 nanosheet could effectively optimize the structure of the nanocomposite, thereby remarkably improving its electron conductivity and structural stability. In parallel, the high pseudo-capacitance contribution ratio of the hybrid showed fast Li+ storage behavior, resulting in admirable rate capability (194.2 mAh g(-1) at 1000 mA g(-1)). Furthermore, under a large current density of 2000 mA g(-1), the hybrids exhibited a satisfying discharge capacity of 150.2 mAh g(-1) and a superior capacity retention of 76.6 % after 250 cycles. The performances of V6O13@rGO are much better than those in pure phase. Evidently, the V6O13@rGO two-dimensional nanosheet has a prospective value for next-generation LIBs cathode materials with satisfying rate and cyclability.
