title: A honeycomb-layered Na3Ni2SbO6: a high-rate and cycle-stable cathode for sodium-ion batteries.
abstract: A honeycomb layered Na3Ni2SbO6 is synthesized as a cathode for sodium-ion batteries. This new host material exhibits a high capacity of 117 mA h g(-1), a remarkable cyclability with 70% capacity retention over 500 cycles at a 2C rate, and a superior rate capability with >75% capacity delivered even at a very high rate of 30 C (6000 mA g(-1)). These results open a new perspective to develop high-capacity and high-rate Na-ion batteries for widespread electric-energy-storage applications.
