Abstract
- A three-dimensional cross-linked Ni-V <subscript>2</subscript> O <subscript>5</subscript> nanomaterial with a particle size of 250-300 nm was successfully prepared in a 1-butyl-3-methylimidazole bromide ionic liquid (IL). The formation of this structure may follow the rule of dissolution-recrystallization and the ionic liquid, as both a dissolution and structure-directing agent, plays an important role in the formation of the material. After calcination of the precursor, the active material (Ni-V <subscript>2</subscript> O <subscript>5</subscript> -IL) was used as an anode for lithium-ion batteries. The designed anode exhibited excellent electrochemical performance with 765 mA h g <superscript>-1</superscript> at a current density of 0.3 A g <superscript>-1</superscript> after 300 cycles, which is much higher than that of a NiVO-W material prepared via a hydrothermal method (305 mA h g <superscript>-1</superscript> ). These results show the remarkable superiority of this novel electrode material synthesized in an ionic liquid.<br />Competing Interests: There are no conflicts to declare.<br /> (This journal is © The Royal Society of Chemistry.)
