“…As a family of typical graphite-like layered materials, vanadium-based oxides have attracted research interest as alternative high-performing anode materials for lithium-ion batteries (LIBs). − Among various vanadium-based oxides, orthorhombic NaV 2 O 5 ( o -NaV 2 O 5 ) is believed to be a very promising candidate because of its stable crystal structure with large interlayer spacing (4.80 Å), excellent transport properties, and unique physical and electrochemical properties (a high theoretical specific capacity of 261.5 mAhg –1 for Li 2 NaV 2 O 5 ). − However, when applied to sodium-ion batteries, o -NaV 2 O 5 shows poor cycling performance . Meanwhile, o -NaV 2 O 5 employed as anode of LIBs has been little reported. , …”
