 A new type of cathode material has been developed by combining VOOH and V4 plus V2O5. It has a unique structure composed of nanoflakes and hollow spheres, and it can store zinc ions efficiently. The resulting cathode has a high specific capacity of 140 mAh per G, after 1000 cycles at 10A slash G, and a fast rate capability due to the presence of V4 plus. This research demonstrates the potential of manipulating valence states in order to create high performing cathodes for advanced batteries.
