Porous V 2 O 5 microspheres: a high-capacity cathode material for aqueous zinc-ion batteries

Porous V O microspheres are synthesized via spray-drying and employed as the cathode material for aqueous zinc-ion batteries (ZIBs). The obtained porous V O microspheres exhibit an ultrahigh reversible capacity and superior rate and cycling performances. In particular, a discharge capacity of 401 mA...

Summary:Porous V O microspheres are synthesized via spray-drying and employed as the cathode material for aqueous zinc-ion batteries (ZIBs). The obtained porous V O microspheres exhibit an ultrahigh reversible capacity and superior rate and cycling performances. In particular, a discharge capacity of 401 mA h g can be achieved at 100 mA g . The specific energy density reaches 286 W h kg , surpassing most reported V-based cathode materials. The super electrochemical performances demonstrate that the porous V O microsphere is a promising cathode material for aqueous ZIBs.
