Vanadium-based oxides are one of the most promising cathode materials, but pure vanadium-based oxides have poor cycle performance and are prone to structural collapse. Hence, many cumbersome synthesis methods have been used to synthesize vanadium-based compounds. Here, we used a very simple one-step hydrothermal method to fabricate disordered V12O26/V2O5 composites with different microstructure, indicating that layered structure is beneficial to improve electrochemical performance of V12O26/V2O5 composites. After assembling the battery, the specific capacity is 374 mAh g(-1) at 0.5 A g(-1), and the capacity remains 211.5 mAh g(-1) after 2500 cycles at 5 A g(-1).
