Rationally designed hollow precursor-derived Zn3V2O8 nanocages as a high-performance anode material for lithium-ion batteries

The Zn3V2O8 nanocages with excellent lithium storage performance was prepared from a rationally designed hollow precursor. The formation mechanism of the precursor and the lithium storage mechanism of the Zn3V2O8 nanocages were investigated in details, respectively.237
