Hydrothermal synthesis of sodium vanadate nanobelts as high-performance cathode materials for lithium batteries

Na0.76V6O15 nanobelts have been successfully synthesized via a facile hydrothermal reaction followed by annealing. For the first time, we evaluate the Na0.76V6O15 nanobelts as cathode for LIBs. Due to the unique layer-by-layer stacked nanobelts structure and good structural stability upon cycling, this material exhibits superior performances including high specific capacity, excellent cyclic stability and high-rate capability.159
