- Abstract
Among various cathode materials for lithium-ion batteries (LIBs), V2O5 stands out due to the unique layered structure, wide ion diffusion channels and higher theoretical specific capacity. However, the inherent low conductivity and poor structure stability of V2O5 lead to the inferior electrochemical properties. In this work, V2O5 nanofibers with high porosity were prepared via electrostatic spinning method combined with subsequent calcination. The obtained V2O5 nanofibers deliver a short ion diffusion path and provide a higher specific surface area. On the basis of the above advantages, the V2O5 nanofibers cathode exhibits impressive performance metrics: 311.6 mAh/g at 0.1 A/g and 223.0 mAh/g at 1 A/g with 99.0% capacity retention after 150 cycles. The above results reveal that the electrodes prepared using the electrostatic spinning technique combined with the heat treatment method display excellent electrochemical properties. Therefore, the V2O5 nanofiber electrode material has a broad application prospect.
