Abstract
In this article, V2O5 with a novel nest-like hierarchical porous structure has been synthesized by a facile solvothermal method and investigated as cathode material for lithium-ion batteries. The nest-like V2O5 with a diameter of about 1.5 µm, was composed of interconnected nanosheets with a highly porous structure. Without other modification, the as-prepared V2O5 electrode exhibited superior capacity. An initial discharge capacity of 330 mAh gâ1 (at a current density of 100 mA gâ1) could be delivered and a stable discharge capacity of 240 mAh gâ1 after 50 cycles is maintained. The excellent performance was attributed to the hierarchical porous structure that could buffer against the local volume change and shorten the lithium-ions diffusion distance.
