- Abstract
Among the cathode materials for lithium-ion batteries (LIBs), vanadium oxides have received extensive attention from researchers due to their abundant reserves and high theoretical specific capacity. Nevertheless, its low electronic conductivity and poor structural stability lead to its poor electrochemical performance. Herein, the V2O5 layered nanofibers prepared by electrostatic spinning technique combined with annealing processes. When the calcination temperature was set to 450 °C, the obtained V2O5 layered nanofiber material (AM450-V2O5) had a uniformly dispersed morphology, which conferred more lithium ion insertion sites and thus accelerated lithium ion insertion/(de)insertion. Based on this, the AM450-V2O5 electrode exhibits a high initial discharge specific capacity (250.7 mAh/g at 0.1 A/g) and excellent cycling stability (82% cycle retention at 1 A/g after 150 cycles). These results indicate that the V2O5 layered nanofibers are highly promising as long-life, high-rate cathode materials for next-generation LIBs.
